BACKGROUND: This study was undertaken in order to compare pregnancy outcome after IVF and ICSI in unexplained and endometriosis-associated infertility using tubal factor infertility as controls. METHODS: This was a retrospective cohort study of early IVF/ICSI pregnancies verified by serum hCG measurement, comparing the subsequent outcome in unexplained (n = 274) and minimal endometriosis-associated (n = 212) with tubal factor (n = 540) infertility as controls. From January 1990 to December 2002, 1026 conception cycles after treatment with IVF or ICSI complied with the inclusion criteria. RESULTS: Live birth rate, twin birth rate after transfer of two embryos and abortion rate prior to 6 weeks of gestation were superior for the unexplained (78.8, 23.5 and 11.7%) compared to endometriosis-associated (66.0, 15.0 and 19.3%) and tubal factor (66.7, 18.1 and 18.0%) infertility groups (P < 0.05). Compared to the endometriosis-associated, the unexplained infertility group attained a higher pregnancy rate after the first treatment cycle (P < 0.05). CONCLUSIONS: The overall better outcome for the unexplained infertility group with respect to live birth rate, twin birth rate and early abortion rate compared to the minimal peritoneal endometriosis-associated and tubal factor infertility groups might be a guide to select diagnostic groups for single embryo transfer and be useful in patient counselling. 相似文献

BACKGROUND: A comparison of the effectiveness of different gonadotrophin preparations in intrauterine insemination (IUI) cycles for patients with unexplained infertility was performed. METHODS: Two hundred and forty-one patients were prospectively randomized using computer-generated random numbers into three groups: 81 in the Follitropin alpha (Group I), 80 in the urinary FSH (uFSH) (Group II) and 80 in the hMG (Group III). The primary outcome was clinical pregnancy rate with duration of stimulation, total gonadotrophin dose, number of dominant follicles, clinical pregnancy rate, multiple pregnancy, miscarriage rate and ovarian hyperstimulation syndrome (OHSS) rate being secondary outcomes. RESULTS: Clinical pregnancy rate was significantly higher in the rFSH group (25.9% in Follitropin alpha, 13.8% in uFSH and 12.5% in HMG groups; P = 0.04). There was no significant difference in terms of duration of stimulation, but mean FSH dose consumed per cycle was significantly lower in the recombinant FSH (rFSH) group compared with others (825 IU in Follitropin alpha, 1107 IU in uFSH and 1197 IU in HMG groups; P = 0.001). The number of follicles > or =16 mm diameter was significantly higher in the rFSH group compared with the uFSH and HMG groups (2.6 in Follitropin alpha, 1.3 in uFSH and 1.4 in HMG groups; P = 0.001). CONCLUSION: rFSH may result in a better outcome in IUI cycles for unexplained infertility. 相似文献

BACKGROUND: Recently, concern has risen about poor obstetrical and neonatal outcome of singletons after IVF/ICSI. Because the population of patients receiving single-embryo transfer (SET) resulting in singleton pregnancies is different from the one that would have become pregnant (with a singleton) before SET was introduced, we wanted to investigate whether the outcome of singleton pregnancies after SET differed from spontaneously conceived singletons. METHODS: The obstetrical and early neonatal outcome of all pregnancies originating from SET after IVF/ICSI procedures between 1 January 1998 and 31 December 2003, was prospectively collected and analyzed. RESULTS: Data from 251 singleton pregnancies and births after SET were analyzed and compared to data from 59,535 spontaneously conceived singletons retrieved from the Centre for Perinatal Epidemiology. The mean birthweight of the singletons after SET was 3322 g (+/-538 SD) versus 3330 g (+/-531 SD) for the spontaneously conceived singletons (P = 0.82). The mean gestational age was 38.7 weeks (+/-1.9 SD) for SET and 38.9 weeks (+/-1.8 SD) for spontaneously conceived singletons (P = 0.06). The proportion of very preterm birth (<32 weeks) was 0.8% in each group, and the proportion of preterm birth (<37 weeks) was 10.0% for SET singletons and 6.24% for spontaneous singletons (P = 0.03). However, mean birthweight of very preterm, preterm and term SET singleton babies was similar to the mean birthweight in every category of gestational age in the spontaneous conceived control group. Stillbirth was 0.4% for both populations (P = 0.99). CONCLUSIONS: Good prognosis patients, in whom SET is applied, do not only have a higher chance of conception but do not have an unfavourable outcome of their singleton baby when compared to spontaneous singletons. 相似文献

BACKGROUND: Single embryo transfer (SET) pregnancies practically lack vanishing twins and may be associated with improved neonatal outcome. Our objective was to compare the obstetric and neonatal outcome of SET singletons with the outcome of singletons following double embryo transfer (DET) and spontaneous conception. METHODS: A 7-year (1997-2003) cohort of fresh SET (n = 269) and DET (n = 230, including 25 vanishing twins) cycles resulting in singleton birth at Helsinki University Central Hospital, Finland, was linked to the Finnish Medical Birth Register and the obstetric and neonatal outcome data compared with that from 15 037 spontaneously conceived singleton pregnancies. RESULTS: The obstetric and neonatal outcome of the SET group was comparable to that in the DET group. Compared with the comparison cohort, gestational hypertension (P = 0.005), placenta praevia (P < 0.001), preterm contractions (P = 0.01) and maternal hospitalization (P < 0.001) was more typical of women in the SET group. After adjusting for age, parity and socio-economic status the SET pregnancies showed increased risks of Caesarean section [odds ratio (OR) 1.54 with 95% confidence interval (CI) 1.18-2.00], preterm birth (OR 2.85; 95% CI 1.96-4.16) and low birthweight (OR 2.01; 95% CI 1.19-3.99) compared with the comparison cohort. CONCLUSIONS: Our results indicate that subject- and infertility-related mechanisms other than the number of transferred embryos influence the neonatal outcome of singleton IVF pregnancies. 相似文献

Multifetal reduction of triplets to twins: a prospective comparison of pregnancy outcome 总被引:5,自引:0,他引:5
Boulot P Vignal J Vergnes C Dechaud H Faure JM Hedon B 《Human reproduction (Oxford, England)》2000,15(7):1619-1623
The aim of this study was to compare the outcome of triplets managed expectantly or by multifetal reduction to twins to assess the potential benefit of fetal reduction. The study design was prospective, comparative and monocentric and the study was conducted in a teaching hospital. Out of 148 women with triplets mostly obtained after infertility treatment, 83 were expectantly managed while 65 chose reduction to obtain twins. Main outcome measures were fetal loss before 24 weeks, premature deliveries before 28, 32 and 34 weeks, rate of low birthweight infants and neonatal and perinatal mortality rates. The fetal loss rate before 24 weeks did not differ between the ongoing group and the reduced group (6 versus 5.4%). Reducing triplets was associated with a significantly lower incidence of the following: prematurity before 28, 32 and 34 weeks (P < 0.001), low birthweight infants whose weights were under the third centile (P < 0.002) and infants whose weights were less than 1000, 1500 and 2000 g (P < 0.001). Neonatal (although apparently lower in the reduced group) and perinatal mortality did not significantly differ. Our results indicate that reduction of triplets to twins is effective to improve preterm birth and fetal growth. 相似文献

Live birth rates after transfer of equal number of blastocysts or cleavage-stage embryos in IVF. A systematic review and meta-analysis 总被引:2,自引:0,他引:2
Papanikolaou EG Kolibianakis EM Tournaye H Venetis CA Fatemi H Tarlatzis B Devroey P 《Human reproduction (Oxford, England)》2008,23(1):91-99
BACKGROUND: Both cleavage-stage and blastocyst-stage embryo transfer policies have advantages and drawbacks. The number of embryos transferred, however, is a crucial parameter that needs to be considered before attempting any comparison. METHODS: An extensive literature search yielded initially 282 studies from which 8 randomized controlled trials met the inclusion criteria: (i) truly randomized design (ii) policy to transfer equal number of embryos in both the cleavage-stage and the blastocyst-stage groups and (iii) published as full text in a peer-review journal. Primary outcome was the live birth rate and secondary outcomes were clinical pregnancy rate, multiple pregnancy rate, cancellation rate and cryopreservation rate. RESULTS: A total of 1654 patients were reviewed. Live birth rate per randomized patient was significantly higher (n = 6 studies) in patients who had a blastocyst-stage transfer as compared to patients with cleavage-stage embryo transfer [odds ratio (OR): 1.39, 95% confidence interval (CI): 1.10-1.76; P = 0.005]. Clinical pregnancy rate (OR: 1.27, 95% CI: 1.03-1.55; P = 0.02) and cancellation rate per patient randomized (OR: 2.21, 95% CI: 1.47-3.32; P = 0.0001) were significantly higher in patients with a blastocyst-stage embryo transfer as compared to patients in whom a cleavage-stage embryo transfer was performed. The cryopreservation rate was significantly higher in the cleavage-stage group (OR: 0.28, 95% CI: 0.14-0.55; P = 0.0002). CONCLUSIONS: The best available evidence suggests that the probability of live birth after fresh IVF is significantly higher after blastocyst-stage embryo transfer as compared to cleavage-stage embryo transfer when equal number of embryos are transferred in the two groups compared. 相似文献

Effect of developmental stage of embryo at freezing on pregnancy outcome of frozen-thawed embryo transfer 总被引:6,自引:0,他引:6

BACKGROUND: The study aim was to investigate the impact of the developmental stage of embryos on pregnancy outcome of frozen embryo transfer (FET). METHODS: The survival rates of embryos after thawing and pregnancy outcome following FET were compared retrospectively between three cryopreservation strategies utilizing either zygote, day 2 or day 3 embryo freezing. RESULTS: A total of 4006 embryos was analysed in 1657 thaw cycles. The highest (P < 0.0001) survival rate (all cells survived) was observed for zygotes (86.5%), followed by day 2 (61.7%) and day 3 (43.1%) embryos. FET was performed in 1586 (95.7%) of all thaw cycles, resulting in overall clinical pregnancy and implantation rates of 20.7 and 14.2% respectively. The delivery rate per transfer was 16.5%, and live birth rate per transferred embryo 11%. There were no significant differences in clinical pregnancy, implantation, delivery and birth rates between frozen zygote, day 2 and 3 embryo transfers. However, an elevated miscarriage rate was observed in the day 3 group (45%) compared with zygotes (21.3%; P = 0.049) and day 2 embryos (18.3%; P = 0.004). The overall efficacy of FET (birth rate per thawed embryo) was 7.3%. The efficacy was lower in day 3 group (4.2%) than in the zygote (7.1%; P = 0.082) and day 2 (7.6%; P = 0.027) groups. CONCLUSIONS: The developmental stage of embryos at freezing has a profound effect on their post-thaw survival, but seems to have little effect on rates of clinical pregnancy, implantation, delivery and birth after FET. The elevated miscarriage rate for day 3 frozen embryo transfers may be caused by damage during freeze-thaw procedures. The low survival rate and elevated miscarriage rate were both responsible for a reduced overall efficacy for day 3 FET when compared with zygotes and day 2 embryos. 相似文献

BACKGROUND: Increased maternal and fetal risks have been reported in pregnancies following unexplained infertility. Our aims were to examine the obstetric and perinatal outcome of singleton pregnancies in couples with unexplained infertility and explore the impact of fertility treatment. METHODS: Women with unexplained infertility were identified from the Aberdeen Fertility Clinic Database. Their unit numbers were matched against the Aberdeen Maternity and Neonatal Databank (AMND) in order to extract obstetric records of those women with subsequent pregnancy outcomes. The general obstetric population served as a control group. RESULTS: Women with unexplained infertility were older [30.8 versus 27.9 years, 95% confidence interval (CI) for difference = +2.4 to +3.4] and more likely to be primiparous (59 versus 40%, 95% CI = +1.3 to +1.9). After adjusting for age and parity they had a higher incidence of pre-eclampsia, abruptio placentae, preterm labour, emergency Caesarean section and induction of labour in comparison with the general population (P < 0.05). Perinatal outcome did not differ between women with unexplained infertility and those of the general population. The multiple pregnancy rate was 5.4% higher following fertility treatment than in women who conceived spontaneously (95% CI = +2.8 to +9.7). CONCLUSIONS: Women with unexplained infertility are at higher risk of obstetric complications which persist even after adjusting for age, parity and fertility treatment. The reasons are however unclear and merit further study. 相似文献

This study reports the obstetric outcome of pregnancies obtained after the transfer of cryopreserved or fresh embryos where the initial procedure was standard in-vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). Pregnancies obtained after frozen IVF (n = 245) or frozen ICSI (n = 177) were compared with a control group of pregnancies after fresh embryo transfer in standard IVF (n = 245) and ICSI (n = 177) cycles were selected as controls. The controls were matched according to maternal age, parity and date of embryo transfer. In the standard IVF group, the biochemical pregnancy rates in the cryopreserved and fresh groups were 18.8 and 9.8% respectively (P < 0.01). In the ICSI group, the biochemical pregnancy rates in the cryopreserved and fresh groups were 16.4 and 6.8% respectively (P < 0.01). The miscarriage rates were comparable between the cryopreserved and fresh groups. However, in the frozen ICSI group the miscarriage rate (26.0%) was significantly higher than in the frozen conventional IVF group (13.1%) (P = 0.001). The frequencies of preterm deliveries, infants with very low birthweight and intrauterine deaths were similar in the groups. The low birthweight rates in the frozen IVF (16.1%) and ICSI (12.1%) groups were significantly lower than those in the fresh IVF (32.2%) and ICSI (32.7%) groups (P < 0.001). The major malformation rates in the frozen IVF (2.4%) and ICSI (2.9%) groups were not different from the major malformation rates in the fresh IVF (4.5%) and ICSI (2.4%) groups. In conclusion, the cryopreservation process had no negative impact on the outcome of pregnancies over 20 weeks of gestation. Long-term follow-up studies are needed in order to prove the safety of the freezing-thawing process. 相似文献

BACKGROUND: This study was done to test the hypothesis that intrauterine insemination (IUI) using a soft-tip catheter results in a higher live birth rate than IUI using a hard-tip catheter. METHODS: Five hundred and forty patients were randomized into those inseminated with a soft-tip catheter (group 1, n = 267) and those inseminated with a hard-tip catheter (group 2, n = 269). Four patients were excluded. Main outcome measures included pregnancy rate and live birth rate per cycle. RESULTS: Both groups were similar with regard to female age, duration of infertility, ovarian stimulation and sperm quality. No significant differences were observed between group 1 and group 2 regarding clinical pregnancy rate per cycle (20 versus 19%), live birth rate per cycle (15 versus 14%), multiple live birth rate per cycle (4 versus 6%) and multiple live birth per total of live births (5 versus 8%, overall 6%), respectively. CONCLUSION: Our hypothesis that IUI using a soft tip catheter results in a higher live birth rate per cycle than IUI using a hard-tip catheter was not confirmed in this study. Multiple live birth rate after treatment with low-dose gonadotrophins and IUI can be kept low (6%). 相似文献

This retrospective study compares in-vitro fertilization and embryo transfer (IVF-ET), gamete intra-Fallopian (GIFT) and zygote intra-Fallopian transfer (ZIFT) for the treatment of male infertility in 266 couples (n = 318 cycles). The IVF-ET technique revealed a total pregnancy rate of 14.1% per cycle and 29.1% per transfer. The conception rate with GIFT was 17.8%; an abortion rate of 50% was noted. The ZIFT procedure scored a 20.9% total pregnancy rate per cycle and 33.3% per transfer. The cumulative take home baby rates per couple for IVF-ET, GIFT and ZIFT were 13.5, 7.0 and 20.0%, respectively. 相似文献

BACKGROUND: Triplet pregnancies are associated with a high risk of miscarriage and early preterm birth. It is uncertain if the outcome is improved by embryo reduction (ER). METHODS: We examined trichorionic triplet pregnancies with three live fetuses at 10-14 weeks of gestation that were managed expectantly or by ER. The two groups were compared for the rates of miscarriage, defined as pregnancy loss before 24 weeks, and preterm delivery prior to 32 weeks. In addition, systematic searches were performed to identify studies comparing outcomes in expectant management versus ER in triplet pregnancies. RESULTS: We combined data from 365 pregnancies managed in our centre with those of five previous studies. In total there were 893 pregnancies. In the ER group (n=482) compared to the expectantly managed group (n=411), the rate of miscarriage was higher [8.1 versus 4.4%; relative risk (RR)=1.83, 95% confidence interval (CI)=1.08-3.16, P=0.036] and the rate of early preterm delivery was lower (10.4 versus 26.7%, RR=0.37, 95% CI=0.27-0.51, P<0.0001). It was calculated that seven (95% CI=5-9) reductions needed to be performed to prevent one early preterm delivery, while the number of reductions that would cause one miscarriage was 26 (95% CI=14-193). CONCLUSIONS: In trichorionic triplets, ER to twins is associated with an increase in the risk of subsequent miscarriage and decrease in risk of early preterm birth. 相似文献

To evaluate the efficacy of gamete intra-Fallopian transfer (GIFT) the
Kaplan-Meier life table method was used to analyse a patient cohort treated
with GIFT between 1991 and 1994. In a tertiary referral centre for
reproductive medicine, 1628 women with a median age of 33 years and various
causes of infertility were included to calculate cumulative pregnancy and
live birth rates. Age and cause of infertility were main factor variables
and the study was based on a total of 2941 consecutive GIFT cycles, leading
to a first clinical pregnancy, and 3052 cycles, leading to a first live
birth. The cumulative pregnancy and live birth rates were 49.6 and 38.8%
respectively, after three initiated cycles and 64.1 and 52.0% respectively,
after five initiated cycles. The multiple pregnancy rate was 22.6%. The
implantation rate of 13.1% after GIFT demonstrates that the developing
embryo benefits from a period of exposure within the environment of the
Fallopian tube. The present results indicate that approximately 50% of
couples will have at least one live baby after five initiated GIFT cycles.
Advancing age was a major negative prognostic factor for the cumulative
live birth rate because of higher cancellation rates, lower implantation
rates and higher pregnancy failure rates.

BACKGROUND: We analysed the difference in maternal, neonatal and total costs after single (SET) versus double day 3 embryo transfer (DET). METHODS: We performed a two-centre prospective study of women in their first IVF/ICSI cycle choosing between SET or DET. Infertility treatment data were gathered from a database; maternal and neonatal outcome data from a case report form (CRF); health economic data from medical acts registered in the CRF for the outpatient part and from hospital bills. SET was performed in 206/367 (56.1%) and DET in 161/367 (43.9%) women. RESULTS: In all, 367 transfers yielded 186 positive pregnancy tests, 148 ongoing pregnancies and 136 live deliveries (50.7, 40.3 and 37.1% per embryo transfer) of which 15 (11.0%) were twins. Live birth rate was 37.4% for SET, 36.6% for DET. Intention-to-treat analysis showed differences for: duration of pregnancy (SET: 39.0 +/- 1.4 versus DET: 38.3 +/- 2.2 weeks; P = 0.055), percentage prematurity (8.5 versus 23.8%; P = 0.033), percentage of neonates hospitalized (5.7 versus 17.9%; P = 0.121) and duration of neonatal hospitalization (6.3 +/- 2.2 versus 10.3 +/- 10.1 days; P = 0.01). Total cost after DET was higher (SET: 4700 +/- 3239 versus DET: 8613 +/- 10 105; P = 0.105), due to significantly higher neonatal costs (451 +/- 957 versus 3453 +/- 8154; P < 0.001) and not to differences in maternal costs (4250 +/- 2882 versus 5160 +/- 4106; P = 0.152). CONCLUSIONS: This prospective health economic study shows that transfer of a single top quality embryo is equally effective as, but substantially cheaper than, double embryo transfer in women <38 years of age in their first IVF/ICSI cycle. 相似文献

The present study compares 465 singleton live deliveries fromin-vitro fertilization/gamete intra-Fallopian transfer (IVF/GIFT)pregnancies with a large control population to evaluate theincidence of pre-term delivery and small for gestational age(SGA) or very small for gestation age (VSGA) babies resultingfrom IVF/GIFT pregnancies. Overall the incidence of SGA or VSGAfrom an IVF/GIFT pregnancy is higher than from the normal obstetricpopulation (SGA odds ratio 1.76, 95% confidence interval (CI):1.382.25 and VSGA odds ratio 1.61, 95% CI: 1.052.46)particularly among primiparous women (SGA odds ratio 1.99, 95%CI: 1.253.16 and VSGA odds ratio 1.97, 95% CI: 1.492.62).After stratifying by the cause of infertility, only women withunexplained infertility had a significantly higher proportionof SGA/VSGA babies. There was a significantly higher incidenceof pre-term deliveries among the young primiparae (odds ratio5.02, 95% CI: 3.098.13). Thus the excess risk of deliveringa SGA/VSGA baby and pre-term delivery from an IVF/GIFT pregnancyseems to be largely confined to women with unexplained infertilityand young primiparae. 相似文献

Fifty-seven patients who underwent hysteroscopic septum resection between
January 1991 and December 1996 were studied; nine patients presented with
recurrent abortions, 46 with infertility (26 primary and 20 secondary), one
with dysmenorrhoea and one with an asymptomatic complete septum. Their
reproductive history included 78 pregnancies: 69 (88.4%) abortions, two
(2.6%) ectopics, two (2.6%) preterm deliveries and five (6.4%) term
deliveries. In patients with infertility, the incidence of unexplained
infertility was 19.6% and the incidence of endometriosis was 26.1%. After
hysteroscopic septum resection, 42 patients were interested in pregnancy.
All patients with recurrent abortions conceived spontaneously. Twenty-one
(63.6%) infertile patients achieved a pregnancy, 13 (61.9%) of them after
treatment with various assisted reproduction techniques. The reproductive
outcome after septum resection yielded 44 pregnancies, including three sets
of twins and one set of triplets reduced to twins: 11 (25%) abortions, one
(2.3%) ectopic pregnancy, two (4.5%) preterm deliveries (both twins), 28
(63.7%) term deliveries and two (4.5%) as-yet ongoing pregnancies. It seems
that the hysteroscopic treatment of uterine septum has a beneficial effect
on pregnancy outcome. A septate uterus does not seem to be an infertility
factor. The achievement of pregnancy is normal in patients with recurrent
abortions, while the chances of conception in patients with infertility
seem to be similar to those for the general infertile population.

Intrauterine insemination treatment in subfertility: an analysis of factors affecting outcome 总被引:4,自引:0,他引:4

A total of 811 intrauterine insemination (IUI) cycles in which clomiphene citrate/human menopausal gonadotrophin (HMG) was used for ovarian stimulation were analysed retrospectively to identify prognostic factors regarding treatment outcome. The overall pregnancy rate was 12.6% per cycle, the multiple pregnancy rate 13.7%, and the miscarriage rate 23.5%. Logistic regression analysis revealed five predictive variables as regards pregnancy: number of the treatment cycle (P = 0.009), duration of infertility (P = 0.017), age (P = 0.028), number of follicles (P = 0.031) and infertility aetiology (P = 0.045). The odds ratios for age < 40 years, unexplained infertility aetiology (versus endometriosis) and duration of infertility < or = 6 years were 3.24, 2.79 and 2.33, respectively. A multifollicular ovarian response to clomiphene citrate/HMG resulted in better treatment success than a monofollicular response, and 97% of the pregnancies were obtained in the first four treatment cycles. The results indicate that clomiphene citrate/HMG/IUI is a useful and cost-effective treatment option in women < 40 years of age with infertility duration < or = 6 years, who do not suffer from endometriosis. 相似文献

The purpose of this study was to compare, in infertile patients, the efficacy of laparoscopic myomectomy versus abdominal myomectomy, in restoring fertility and to evaluate the obstetric outcomes. Between January 1993 and January 1998, 131 patients of reproductive age, with anamnesis of infertility, underwent myomectomy because of the presence of at least one large myoma (diameter greater than or = 5 cm). Patients were randomly selected for treatment by laparotomy (n = 65) or laparoscopy (n = 66). The two groups were homogeneous for number, size and position of large myomata. Significant differences were found in the post-operative outcome: febrile morbidity (> 38 degrees C) was more frequent in the abdominal than in the laparoscopic group (26.2 versus 12.1%; P < 0.05). Laparotomy caused a more pronounced haemoglobin drop (2.17 +/- 1.57 versus 1.33 +/- 1.23; P < 0.001); three patients received a blood transfusion after laparotomy and none after laparoscopy. The post-operative hospital stay was shorter in the laparoscopic group (142.80 +/- 34.60 versus 75.61 +/- 37.09 h; P < 0.001). No significant differences were found between the two groups as concerns pregnancy rate (55.9% after laparotomy, 53.6% after laparoscopy), abortion rate (12.1 versus 20%), preterm delivery (7.4 versus 5%) and the use of Caesarean section (77.8 versus 65%). No case of uterine rupture during pregnancy or labour was observed. 相似文献
