A successful pregnancy after intracytoplasmic sperm injection and embryo transfer in a patient with endometrial cancer who was treated conservatively

OBJECTIVE: To describe a patient with polycystic ovary syndrome (PCOS) conceiving with intracytoplasmic sperm injection (ICSI) and embryo transfer after conservative treatment of early stage endometrial cancer. DESIGN: Case report. SETTING: Tertiary center for assisted reproductive technologies.A 32-year-old woman with PCOS, primary infertility of 4 years duration, and grade 1 endometrioid endometrial cancer. INTERVENTION(S): Assessment of myometrial invasion and extrauterine spread with magnetic resonance imaging (MRI) and explorative laparotomy. High-dose progestin treatment and ICSI and embryo transfer. MAIN OUTCOME MEASURE(S): Successful take-home baby and no residual endometrial cancer. RESULT(S): A healthy normal female infant with a birth weight of 1740 g was born by cesarean section at 30 weeks' gestation. No residual cancer was detected at the follow-up curettage performed 2 months after the delivery. CONCLUSION(S): Conservative uterus-preserving treatment may be considered in patients with early stage endometrial cancer. Assisted reproductive technologies may be used in such patients for immediate achievement of pregnancy.     

Serum progesterone concentration and live birth rate in frozen–thawed embryo transfers with hormonally prepared endometrium

Research question

Is serum progesterone measurement on the day of embryo transfer associated with outcome of frozen–thawed embryo transfer (FET) in cycles using hormonal replacement therapy (HRT) for endometrium preparation?

CONCLUSION(S): Conservative management of International Federation of Gynecology and Obstetrics grade I adenocarcinoma of the endometrium allows preservation of childbearing.     

Establishment of criteria for elective single embryo transfer at day 2 or day 3 by analyzing cases with successful implantation of all embryos transferred

AIM: Elective transfer of two good-quality embryos has been used to avoid triplet or high-order multiple pregnancies. However, the rate of twin pregnancies has remained fairly unchanged. In the present study, criteria for elective single embryo transfer (eSET) at day 2 or day 3 were established by analyzing cases with successful implantation of all embryos transferred. METHODS: A total of 685 fresh or frozen-thawed embryo transfers following in vitro fertilization/intracytoplasmic sperm injection between April 2002 and March 2006 were performed. Only embryo transfers at day 2 or day 3, but not at blastocyst stage, were included. Successful implantation of all embryos transferred was obtained in 17 pregnancy cycles. RESULTS: Thirty-one gestational sacs with fetal heartbeats were obtained by a total of 31 embryo transfers in 17 infertile women. The average age was 32.6 years (23-38), and 14 (82.3%) of the 17 women were <36 years old. Fifteen (88.2%) of the 17 pregnancies were established at the first attempt of assisted reproductive technology (ART). Of the 17 women, eight (47.1%) women were multigravida and four (23.5%) women were multipara. The indications for ART or insemination methods did not seem to be related to the pregnancy results. Twenty-nine (93.5%) of 31 embryos implanted were considered good-quality embryos. Of the 17 fresh embryos transferred at day 2, 15 were at the 4-cell stage and two were at the 5-cell stage. Of the 11 fresh embryos transferred at day 3, one was at the 6-cell stage, two were at the 7-cell stage and eight were at the 8-cell stage. CONCLUSION: The criteria for eSET at day 2 or day 3 were established as follows: <36 years of age, a first treatment cycle and more than two good-quality embryos developed at least to the 4-cell stage at day 2, or 6-cell stage at day 3. Additionally, the past history of pregnancy or delivery should be considered, as patients positive for such history might have better implantation ability. eSET can be highly recommended to avoid twin pregnancies in subjects with the established criteria.     

Clinical evaluation of frozen/thawed embryo transfer following transport of oocytes and embryos

Background and Aims  We evaluated the efficacy of the transport oocyte/embryo frozen/thawed embryo transfer method, in which oocytes or embryos were transported from satellite clinics to the main assisted reproductive technology (ART) center, and surplus embryos were placed in cryopreservation. Methods  We evaluated 41 cycles in 34 patients in the transport oocyte group (TO group). In the TO group the oocytes were collected at the satellite clinics, transported to the main ART center and underwentin vitro fertilization or intracytoplasmic sperm injection. Surplus embryos were used for frozen/thawed embryo transfer. We also evaluated 17 cycles in 10 patients in the transport embryo group (TE group), where surplus embryos were transported to the main ART center and used for frozen/thawed embryo transfer; and 189 cycles in 134 patients in the center group (C group), where surplus embryos collected at the same time at the main ART center were used for frozen/thawed embryo transfer. Oocytes were transported from satellite clinics in HEPES buffered human tubal fluid (HTF) culture medium, and embryos in 30% synthetic serum substitute + HEPES buffered HTF, using a portable incubator we devised. Results  The proportions of undamaged embryos after freeze/ thawing were 47% for the C group, 46% for the TO group, and 46% for the TE group. The numbers of embryos transferred were 2.0 ± 0.7 for the C group, 2.0 ± 0.6 for the TO group, and 2.2 ± 0.4 for the TE group. The rate of embryo transfer was 63% for the C group, 68% for the TO group, and 76% for the TE group. Pregnancy rates per patient were 16% for the C group, 24% for the TO group, and 40% for the TE group. The embryo survival rates (number of embryos with ≥50% viable blastomeres/total number of embryos) were 55% for the C group, 60% for the TO group, and 54% for the TE group. No significant differences were seen between the C group and either the TO or TE groups in any of these parameters. Conclusions  Favorable results were achieved with the transport oocyte/embryo frozen/thawed embryo transfer method, and it is suitable for widespread clinical application.

Effect of single embryo transfer on the risk of preterm birth associated with in vitro fertilization

Purpose

To determine whether elective single embryo transfer (eSET) reduces the risk of preterm delivery associated with in vitro fertilization (IVF).

Methods

This is an observational study of 3125 eSET cycles performed from 2008 to 2009 and reported to the Society for Assisted Reproductive Technology (SART) database. Preterm delivery rates were compared to the overall preterm delivery rate among all patients undergoing IVF over the same time period.

Results

The 3125 eSET cycles resulted in 1507 live births (live birth rate 48.2 %) Among these deliveries were 27 twins (1.8 %) and one set of triplets (0.07 %). The overall preterm delivery rate (20–37 weeks gestation) following eSET was 17.6 % (269/1527). This is significantly greater than the preterm birth rate for all patients undergoing IVF over the same time period (12 %, P < 0.001).

Conclusions

Elective single embryo transfer does not reduce the risk of preterm delivery associated with in vitro fertilization (IVF).     

Clinical study on embryo transfer after human in vitro fertilization

One hundred forty-six embryo transfers were carried out in the In Vitro Fertilization (IVF) Clinic at St. Pierre Hospital, Brussels, between November 1983 and February 1985. In each of these cases a series of characteristics of the replacement procedure was systematically rates indicated that (i) no significant differences appeared among three different operators, (ii) the absence or occurrence of cervical bleeding and subjective evaluation of the procedure were related to the chances of establishing a pregnancy, and (iii) the duration of replacement had no influence on the outcome of trials. A prospeative randomized study of 100 replacements showed that (i) no better pregnancy rate was obtained by placing patients in the knee-to-chest rather than the dorsal position and (ii) the addition of a rigid external sleeve to the catheter did not provide any advantage. A simplified method of replacement is thus advocated.     

Effectiveness of high‐dose transvaginal progesterone supplementation for women who are undergoing a frozen‐thawed embryo transfer

Purpose

To evaluate the effectiveness of high‐dose progesterone supplementation for women who are undergoing a frozen‐thawed embryo transfer (FET).

Methods

Among the 2010 FET cycles that were included in the present study, 1188 were 1200 mg/d of vaginal progesterone, while 822 were 900 mg/d. The dose of progesterone that was used was decided by the treatment period and additional progesterone supplementation was used when the serum progesterone levels were <9 ng/mL on luteal day 5.

Results

The clinical pregnancy rate was higher in the 1200 mg group than in the 900 mg group. The mean serum progesterone level on luteal day 5 in the 1200 mg and 900 mg groups was 12.6 ng/mL and 13.4 ng/mL, respectively. The rate of additional progesterone supplementation was higher in the 1200 mg group. A logistic regression analysis identified a younger age (≤37 years) and the use of 1200 mg progesterone as independent predictive factors for the clinical pregnancy outcome. The analysis of the infant outcomes revealed no significant difference in the distribution of birth ages and weights.

Conclusion

High‐dose transvaginal progesterone of 1200 mg/d as luteal support contributed to good pregnancy outcomes.     

Endometrial thickness significantly affects clinical pregnancy and live birth rates in frozen-thawed embryo transfer cycles

In order to explore the relationship between endometrial thickness on the day of embryo transfer and pregnancy outcomes in frozen-thawed embryo transfer (FET) cycles, we retrospectively analyzed data from 2997 patients undergoing their first FET cycles from January 2010 to December 2012. All patients were divided into three groups (Group A, ≤8?mm; Group B, 9–13?mm; Group C, ≥14?mm) according to the endometrial thickness on embryo transfer day. Compared with patients in the other two groups, patients with thin endometrial thickness in Group A had significantly lower clinical pregnancy rate (33.4%, 41.3% and 45.4%, p?p?p?p?相似文献
