Objective: To investigate the impact of antithyroid antibody on pregnancy outcome following the in vitro fertilization and embryo transfer (IVF-ET).Methods: A total of 90 patients (156 cycles) positive for antithyroid antibody (ATA+ group) and 676 infertile women (1062 cycles) negative for antithyroid antibody (ATA- group) undergoing IVF/ICSI from August 2009 to August 2010 were retrospectively analyzed.Results: There was no significant difference in the days of ovarian stimulation, total gonadotropin dose, serum E2 level of HCG day and number of oocytes retrieved between the two groups. The fertilization rate, implantation rate and pregnancy rate following IVF-ET were significantly lower in women with antithyroid antibody than in control group (64.3% vs 74.6%, 17.8% vs 27.1% and 33.3% vs 46.7%, respectively), but the abortion rate was significantly higher in patients with antithyroid antibody (26.9% vs 11.8%).Conclusion: Patients with antithyroid antibody showed significantly lower fertilization rate, implantation rate and pregnancy rate and higher risk for abortion following IVF-ET when compared with those without antithyroid antibody. Thus, the presence of antithyroid antibody is detrimental for the pregnancy outcome following IVF-ET. 相似文献

To investigate the impact of anti-nuclear antibodies (ANAs) on the outcome of in vitro fertilization-embryo transfer (IVF-ET), 66 (96 cycles) infertile women positive for anti-nuclear antibodies (ANA+ group), and 233(285 cycles) infertile women negative for ANAs (ANA? group) were enrolled. The clinical characteristics and IVF outcome were compared between the two groups. In the ANA+ group, the proportion of MII oocytes and two-pronuclear zygotes (2PN), cleavage rate, number of available embryos and proportion of available embryos, number of high-quality embryos and proportion of high-quality embryos were significantly lower than those in the ANA? group. In addition, the pregnancy rate and implantation rate in patients positive for ANA was markedly lower than the ANA? patients (28.1% vs 46.4%, 15% vs 25.7%, respectively). Thus, our findings suggest that the presence of ANAs significantly interfere with the oocyte and embryo development, as well as reduce implantation and pregnancy rate in patients undergoing IVF treatment. 相似文献

PROBLEM: L-selectin ligand has displayed mediating adhesion at the maternal-fetal interface. Therefore, we investigated the impact of L-selectin ligand on establishing pregnancy in women undergoing in vitro fertilization and embryo transfer (IVF-ET). METHOD OF STUDY: Endometrium between cycle days LH +6 to +9 was obtained from 56 Chinese women referred for IVF and tested for L-selectin ligand by immunohistochemistry and Western blot. The standard gonadotropin-releasing hormone agonist long protocol was used for ovarian stimulation. RESULTS: L-selectin ligand was localized in the endometrial gland and luminal epithelial cells. Western blot analysis of endometrium identified four bands and levels of component 1, 2 and 4 were significantly higher in the pregnancy group than in the non-pregnancy group (P < 0.05). Clinical pregnancy and implantation rates were higher in patients with high level L-selectin ligand compared with those with low level (53.6%versus 25.0%, and 27.1%versus 12.1%, respectively, P < 0.05). CONCLUSION: The presence of higher level L-selectin ligand was associated with a better pregnancy outcome. 相似文献

BACKGROUND: Infertile women positive for thyroid antibodies suffer from a poor pregnancy/delivery outcome, although conflicting data have been published. Our objective was to investigate if levothyroxine (LT4) exerts any effect on pregnancy and/or delivery rates in thyroid peroxidase antibody (TPOAb)-positive (+) women undergoing assisted reproductive technologies. METHODS: Patients undergoing treatment were screened for TPOAb, thyroid-stimulating hormone (TSH) and free thyroxine (FT4). A total of 72 (15%) out of the 484 euthyroid women selected were TPOAb (+). These 72 patients were randomly divided into two groups: group A (n = 36) underwent LT4 treatment, group B (n = 36) placebo. Group C consisted of 412 women (85%) who were TPOAb negative (-). All patients received controlled ovarian stimulation. The endpoints of treatment were pregnancy rate, miscarriage rate and delivery rate. RESULTS: No differences in pregnancy rate were observed between the three groups. Miscarriage rate was higher in TPOAb (+) in comparison to TPOAb (-) [relative risk: 2.01 (95% CI = 1.13-3.56), P = 0.028]. CONCLUSIONS: The pregnancy rate is not affected either by presence of TPOAb or treatment with LT4. However, TPOAb (+) women show a poorer delivery rate compared to TPOAb (-). LT4 treatment in TPOAb (+) does not affect the delivery rate. 相似文献

PROBLEM: To investigate whether antithyroid antibodies (ATAs) affect the pregnancy outcome in euthyroid women undergoing in vitro fertilization-embryo transfer (IVF-ET). METHOD OF STUDY: Thyroid peroxidase antibody (TPOA) and thyroglobulin antibody (TGA) were measured by radioligand assay kits that were used as ATAs in 79 patients with tubal or unexplained infertility who were enrolled in an IVF-ET program. Women who were positive for antinuclear antibody, lupus anticoagulant, anticardiolipin antibody, and rheumatoid factor were excluded from our study. The study group comprised 28 (29.1%) euthyroid women who were positive for TPOAs, TGAs, or both. Fifty-one euthyroid women without ATAs served as control subjects. The results were analyzed with linear regression analysis, Student's f-test, Mann-Whitney U test, Kruskal-Wallis analysis of variance, χ2 test, and Fisher's exact test. RESULTS: There were no significant differences between the study group and the control group in patient characteristics such as age, infertility duration, and hormonal profile. There were also no significant differences between the two groups with respect to the number of retrieved oocytes, the fertilization rate, the number of embryos frozen, and the number of embryos transferred. There were no correlations between ATA (TPOA and TGA) titers and the fertilization rate. The clinical pregnancy rate per cycle was significantly lower in the study group, with 26.3% (10/38), compared with 39.3% (35/89) in the control group. The biochemical pregnancy rate per cycle and the miscarriage rate were significantly higher in the study group, 18.4% (7/38) and 40.0% (4/10), respectively, compared with 5.6% (5/89) and 11.4% (4/35), respectively, in the control group. In the study group, both TPOA and TGA titers were significantly higher in the biochemical pregnancy group than in the clinical pregnancy group or the nonpregnancy group. In 10 women with ATAs who achieved pregnancy after IVF-ET, both TPOA and TGA titers were significantly higher in the miscarriage group than in the ongoing pregnancy/delivery group. CONCLUSION: ATAs in euthyroid women with tubal or unexplained infertility have an association with a poor pregnancy outcome after IVF-ET treatment. 相似文献

PROBLEM: It has been shown that the presence of antinuclear antibody (ANA) might reduce pregnancy rates after in vitro fertilization-embryo transfer (IVF-ET). However, the mechanism of implantation failure by ANA has not yet been clarified. This study was performed to investigate the impact of ANA on pregnancy rates after IVF-ET, and the necessity of specific medication for infertile women who have ANA in their sera. METHOD OF STUDY: A total of 108 infertile women were treated by IVF-ET or intracytoplasmic sperm injection (ICSI)-ET. ANA was examined by an indirect fluorescent antibody procedure. Data from women under 40 years old were analyzed retrospectively. RESULTS: The implantation rates per embryo transferred in the first treatment cycles were 14.8% (eight of 54) and 32.4% (33 of 102), in women with and without ANA, respectively. There was a significant difference in the implantation rates between the two groups (P < 0.05). The pregnancy rates per ET in the first treatment cycles were 28% (seven of 25) and 54.2% (26 of 48), respectively. There was also a significant difference in the pregnancy rates between the two groups (P < 0.05). Afterwards, treatments with IVF-ET or ICSI-ET were repeatedly performed for unsuccessful patients, without any specific medication for ANA. The average ET cycles were 1.80 +/- 1.13 and 1.27 +/- 0.54, in women with and without ANA, respectively. The cumulative pregnancy rates per patient were 68% (17 of 25) and 55.6% (35 of 63), respectively. There was no significant difference in the overall pregnancy rates between the two groups. CONCLUSIONS: These findings suggest that ANA might have an impact on implantation failure in women treated by IVF-ET or ICSI-ET. ANA reduced the pregnancy rates in the first IVF-ET or ICSI-ET cycles but not the cumulative pregnancy rates without medication. This indicates that the mechanisms of implantation failure by ANA could be solved, and effective and safe medication should be developed for better implantation rates, especially in the first treatment cycle. 相似文献

BACKGROUND: Poor ovarian and endometrial responses to gonadotrophin stimulation in assisted reproduction techniques lead to decreased pregnancy rates. The aim of the present study was to test the hypothesis that low-dose aspirin started prior to controlled ovarian stimulation improves ovarian responsiveness, pregnancy rate (PR) and pregnancy outcome. METHODS: A total of 374 women who were to undergo IVF/ICSI were randomized to receive 100 mg of aspirin (n=186) or placebo (n=188) daily. Treatment was started on the first day of controlled ovarian stimulation. It was continued until menstruation or a negative pregnancy test. Pregnant women continued the medication until delivery. The main outcome measures were the number of oocytes, number and quality of embryos, the clinical PR and pregnancy outcome. RESULTS: The mean (+/-SD) number of oocytes (12.0+/-7.0 versus 12.7+/-7.2), the total mean number of embryos (5.82+/-4.35 versus 5.99+/-4.66), the mean number of top quality embryos (0.99+/-1.39 versus 1.18+/-1.51) and the number of embryos transferred (1.64+/-0.64 versus 1.63+/-0.71) did not differ in the aspirin and placebo groups. Between the aspirin and placebo group, there was no statistically significant difference in clinical PR per embryo transfer (25.3%, n=44 out of 174 versus 27.4%, n=48 out of 175) or clinical PR per cycle initiated (23.7% versus 25.5%). Birth rate per embryo transfer did not differ significantly between the aspirin (18.4%) and placebo (21.1%) groups. The incidence of poor responders [12 (6.5%) versus 13 (6.9%)] was similar in both groups. CONCLUSIONS: The present results indicate that low-dose aspirin treatment does not have any beneficial effect on ovarian responsiveness, PR and pregnancy outcome in unselected women undergoing IVF/ICSI. 相似文献

An oocyte donation programme was carried out in 122 patientsaged between 40 and 49 years for a total of 225 replacementcycles. Eggs were donated by 103 women undergoing assisted reproductiontechnologies in our infertility centre. Recipients were dividedinto different groups according to whether they were menopausal(group A) or cyclic and treated with short- (group B) or long-term(group C) gonadotrophin-releasing hormone analogues. In groupC, the ovarian suppression of the patients was prolonged withthe aim of producing a type of artificial menopause. Oocytedonors were aged between 21 and 35 years, and were equally distributedbetween the different groups. There were significant differencesin pregnancy and implantation rates according to ovarian status:30.8 and 16.1% respectively in group A, 30.6 and 17.7% respectivelyin group C versus 10.4 and 5.6% respectively in group B. Apartfrom improved pregnancy and implantation rates in cyclic womenaged >40 years after long-term down-regulation, these dataseem to demonstrate an important role for the endometrium inthe implantation process. 相似文献

BACKGROUND: GnRH agonist administration in the luteal phase was reported to beneficially affect the clinical outcome of intracytoplasmic sperm injection (ICSI) and embryo transfer (ET) cycles. This double blind, randomized, placebo controlled trial evaluates whether a single dose GnRH agonist administered 6 days after ICSI increases ongoing pregnancy rates following ET in cycles stimulated with the long GnRH agonist protocol. METHODS: Five hundred and seventy women undergoing ET following controlled ovarian stimulation with a long GnRH agonist protocol were included. In addition to routine luteal phase support with progesterone, women were randomized to receive a single 0.1 mg dose of triptorelin or placebo 6 days after ICSI. Randomization was done on the day of ET according to a computer generated randomization table. Ongoing pregnancy rate beyond 20th week of gestation was the primary outcome measure. The trial was powered to detect a 12% absolute increase from an assumed 38% ongoing pregnancy rate in the placebo group, with an alpha error level of 0.05 and a beta error level of 0.2. RESULTS: There were 89 (31.2%) ongoing pregnancies in the GnRH agonist group, and 84 (29.5%) in the control group (absolute difference +1.7%, 95% confidence interval -5.8% to +9.2%). Implantation, clinical pregnancy and multiple pregnancy rates were likewise similar in the GnRH agonist and placebo groups. CONCLUSIONS: Single 0.1 mg triptorelin administration 6 days after ICSI following ovarian stimulation with the long GnRH agonist protocol does not seem to result in an increase >or=12% in ongoing pregnancy rates. 相似文献

Ovarian volume measurements have been recently shown to be predictive of response to ovarian stimulation. Women with small ovarian volumes, i.e. <3 cm(3), have a higher incidence of cycle cancellation, together with a lower peak oestradiol concentration, lower number of retrieved oocytes, and lower pregnancy rates, compared with women with larger ovarian volumes. We prospectively investigated whether a higher dose, microdose flare gonadotrophin-releasing hormone (GnRH) agonist protocol, can improve IVF outcome in women with a small ovarian volume. Only the first IVF cycle was reviewed. In total, 109 women aged <40 years undergoing 109 cycles were prospectively evaluated. Women with an ovarian volume of < or =3 cm(3) noted on the day of luteal GnRH agonist administration had their stimulation regimen changed to a more aggressive microdose flare GnRH agonist protocol. In all, 30 women (27.5%) with an ovarian volume of <3 cm(3), and 79 women (72.5%) with an ovarian volume of >3 cm(3) were compared. Women with an ovarian volume of <3 cm(3) had a significantly higher incidence of unexplained infertility as their presenting aetiology, compared with women with a larger ovarian volume (33 and 8.6%, P = 0.0036). There was a significant negative correlation between age and ovarian volume, and between day 3 FSH concentration and ovarian volume. We also report a significant positive correlation between body mass index and ovarian volume. There was also a significant positive correlation between ovarian volume and the number of oocytes retrieved. Despite a trend towards higher day 3 FSH concentrations, a significantly longer duration of stimulation, higher gonadotrophin requirements, and lower oocyte yield, the implantation and pregnancy rates were comparable between the two groups. Women with a small ovarian volume noted at baseline ultrasound can have comparable implantation and pregnancy rates to those with larger ovarian volumes with the use of a higher dose gonadotrophin, microdose GnRH agonist stimulation. 相似文献

Variations in blood concentrations of antiphospholipid antibodies (APA) were investigated through the course of pregnancy in women who had a history of recurrent pregnancy loss, and were related to changes in pregnancy outcome. Serial measurements of APA were made in 16 women with antiphospholipid syndrome (APS) and 16 with negative APA tests pre-pregnancy. There was considerable intraindividual variation in test results through pregnancy. There was a significantly higher ratio of dilute Russell's viper venom time and IgG ACA titre in the first trimester compared with results pre-pregnancy in women with APS. Furthermore, transiently positive APA results were noted in the control group during pregnancy and some women with antiphospholipid syndrome tested negative for APA in mid- and late pregnancy. We have demonstrated clinically important variations in the results of tests for APA during pregnancy in women with APS. 相似文献

BACKGROUND: Oocyte donation provides us with an opportunity to study the clinical outcome of oocytes, retrieved from women undergoing coasting, in recipients in whom endometrial receptivity is unaltered by the coasting procedure. Thus, our aim was to describe oocyte donation outcome in donors undergoing coasting, the oocyte and embryo quality obtained from these cycles, and to determine the influence of coasting duration in the cycle outcome. METHODS: Matched-paired analysis included 15 oocyte donors with high response to ovarian stimulation and submitted to coasting and 15 oocyte donors with normal response to ovarian stimulation and not undergoing coasting. There were 38 oocyte recipients who shared oocytes from the donors under coasting and 37 from donors not undergoing coasting. RESULTS: Both groups of donors were comparable in terms of days and dose of ovarian stimulation, oocytes retrieved, metaphase II oocytes obtained, and in the appearance of ovarian hyperstimulation syndrome. Both groups of oocyte recipients were comparable in male-associated factor, pregnancy and implantation rates, as well as in embryo quality. Recipients from donors with coasting for >4 days had significantly lower implantation and pregnancy rates. CONCLUSIONS: the outcome of oocyte donation from donors undergoing coasting is not impaired, as good implantation and pregnancy rates are achieved. Embryo quality, according to our current standards, does not seem to be compromised by coasting itself. However, if coasting in oocyte donors is prolonged for >4 days there is a significant decrease in both implantation and pregnancy rates. 相似文献

The purpose of this study was to investigate the relationship between mid-luteal phase echo patterns and IVF-embryo transfer outcome in women who have demonstrated adequate endometrial development by the late proliferative phase. A prospective study was carried out of 86 patients undergoing IVF-embryo transfer and 86 patients undergoing frozen embryo transfer who all underwent sonographic monitoring of the endometrium 3 days after embryo transfer. The cycles were classified into two groups: those with the homogeneous hyperechogenic (HH) pattern and those without it. The women who had an HH pattern had higher clinical pregnancy (32.8 versus 10.7%, P < 0.05) and implantation rates in stimulated cycles (14.3 versus 4.1%, P < 0.05 respectively) than those that did not. There was no significant difference in the clinical pregnancy or implantation rates by echo pattern (18.2 and 8.1% for non-HH and 18. 7 and 8.0% for HH respectively) in frozen embryo transfer cycles. These data demonstrate that in embryo transfer cycles where ovarian stimulation was used, there were decreased pregnancy and implantation rates in cycles where the HH pattern was not observed 3 days after transfer. The failure of the endometrium to display this pattern may indicate some endometrial abnormality resulting in implantation defects. 相似文献

In-vitro fertilization outcome in women with hydrosalpinx 总被引:8,自引:13,他引:8

Recent studies have suggested that the presence of hydro-salpinxhas a negative effect on in-vitro fertilization (IVF) outcome,with markedly diminished implantation and pregnancy rates, andincreased early pregnancy loss. We evaluated the impact of hydrosalpinxon IVF outcome in a large population with tubal factor infertility:63 patients with hydrosalpinx and 60 without hydrosalpinx (nohydro-salpinx) underwent 103 and 89 IVF cycles respectively.Hydrosalpinx was diagnosed by hysterosalpingography and/or laparoscopyprior to IVF. Patients were further subdivided into those withor without elevated quantitative serum Chlamydia trachomatisIgG antibody (Ab) titres. All couples with elevated serum Abtitres (I: 16 or more) were treated with doxycycline (100 mgbid.) 10 days prior to the first IVF cycle. In all, 88 women(71.5%) had elevated C. trachomatis Ab: 47 women (74.6%) withhydrosalpinx had elevated titres, compared to 41 (683%) in theno hydrosalpinx group. There were no significant differencesin mean age, number of mature oocytes obtained, and number ofembryos transferred between the two groups. There was a trendfor a higher implantation rate and ongoing pregnancy rate inthe no hydrosalpinx group compared to the hydrosalpinx group(12.6 versus 9.8%, and 33.7 versus 24.8% respectively); however,this did not reach statistical significance. The incidence ofearly pregnancy loss was similar in the two groups. Two ectopicpregnancies were noted in the hydrosalpinx group compared tonone in the no hydrosalpinx group. As expected, the prevalenceof elevated titres of C. trachomatis IgG Ab in patients withtubal factor infertility presenting for assisted reproductivetreatment was high. In contrast to recently published reports,our study did not confirm a negative effect of hydrosalpinxon IVF outcome when antibiotic treatment was given prior toassisted reproductive treatment. Prospective multicentre studiesevaluating the effect of hydrosalpinx and its treatment on IVFoutcome are needed. 相似文献
