Progesterone levels on the hCG day and outcomes in vitro fertilization in women with polycystic ovary syndrome

Background

The purpose of this study was to determine the incidence of premature luteinization in patients with polycystic ovary syndrome and compared the main determinants of success in in-vitro fertilization in PCOS patients with and without premature luteinization.

Methods

Retrospective analysis of 180 PCOS women of Chinese Han origin with infertility who underwent controlled ovarian hyperstimulation (COH) with an exogenous gonadotropin/GnRH antagonist protocol. Hormone levels on the hCG day and IVF outcomes were assessed.

Results

The incidence of premature luteinization was 23.3 %. Compared with PCOS patients without premature luteinization, PCOS patients with premature luteinization(PL) had a higher number of oocytes retrieved (18.20 ± 6.6 vs 15.08 ± 7.3, p = 0.037) and a higher fertilization rate (72.9 ± 1.9 vs63.1 ± 2.3, p = 0.033), but clinical pregnancy rates were no statistical significance (53.3 vs 56.0, p = 0.836). Though the implantation rate was higher in no premature luteinization patients, but the difference was not statistically significant (37.7 vs 30.3, p = 0.115).

Conclusion

The PCOS patients with premature luteinization had a higher fertilization rate and high number of oocytes retrieved, and the similar implantation rate and clinical PRs as PCOS patients without premature luteinization.     

Pregnancy outcomes in in vitro fertilization cycles with serum estradiol drop prior to human chorionic gonadotropin.

OBJECTIVE: To study the effect of an unpredictable drop in serum estradiol prior to hCG administration on pregnancy outcomes in in vitro fertilization cycles. METHODS: 3653 consecutive IVF cycles from January 1, 1998 to December 31, 2000 at Brigham and Women's Hospital were reviewed, and 65 cycles in which oocyte retrieval (ER) was performed following a drop in serum estradiol (E(2)) not associated with intentional withdrawal of gonadotropins were identified. Daily gonadotropin dose was decreased at some time in 25 of these cycles, while the remaining 40 cycles did not have a reduction in gonadotropin dose. A retrospective case-control study of the respective live birth rates and pregnancy loss rates of patients with unpredictable E(2) drops in the 65 study cycles were compared to 65 age matched controls. RESULTS: Live birth rates (32% vs. 35%, p=0.72) and pregnancy loss rates (28% vs. 30%, p=0.76) were similar for all study and control groups respectively. There were no differences in live birth and pregnancy loss rates in cycles undergoing gonadotropin dose reduction (40% vs. 44%, p=0.78 and 29% vs. 39%, p=0.70) and cycles without gonadotropin dose reduction (28% vs. 30%, p=0.81 and 27% vs. 20%, p=0.72). CONCLUSIONS: In the absence of coasting, a drop in serum estradiol levels during GnRH-agonist downregulated controlled ovarian hyperstimulation for IVF prior to hCG is not associated with a decrease in live birth rates or pregnancy loss rates.     

Consequences of premature progesterone elevation on the outcome of in vitro fertilization: insights into a controversy

Objective: To investigate whether the consequences of premature P elevation on IVF-ET outcome are modulated by the quality of the ovarian response to controlled ovarian hyperstimulation (COH).Design: Retrospective analysis.Setting: Assisted Reproduction Unit, Clamart, France.Patient(s): One thousand twelve women undergoing 1,189 IVF-ET cycles.Intervention(s): Patients underwent COH with a time-released GnRH agonist and hMG. The ovarian response to COH was classified as strong (550 hMG ampules, peak E₂ levels > 2,500 pg/mL, and ≥10 mature oocytes; n = 340), weak (> 50 hMG ampules, peak E₂ levels ≤1,500 pg/mL, and ≤5 mature oocytes; n = 285), or intermediate (remaining cases; n = 564). The IVF-ET outcome in each group was analyzed according to whether or not plasma P levels exceeded 0.9 ng/mL.Main Outcome Measure(s): Pregnancy rates (PRs).Result(s): Clinical PRs were similar irrespective of low or high P levels in the strong (30% and 34%, respectively) and intermediate (31% and 30%, respectively) groups. However, in the weak group, P levels > 0.9 ng/mL were associated with lower PRs (3.2% and 23%, respectively).Conclusion(s): In the presence of an adequate response to COH, P levels > 0.9 ng/mL were not associated with lower PRs, indicating that good embryo quality may compensate for the adverse endometrial effects of P. Conversely, when the response to COH was weak, premature P elevation led to drastically reduced PRs.     

In vitro fertilization programmed for weekday-only oocyte harvest: Analysis of outcome based on actual retrieval day

Objective: Our aim was to assess the effect of the day of ovum retrieval on outcome in an IVF program scheduled for weekday-only ovum retrievals. Design: This was a retrospective study of patients who underwent transvaginal ultrasound-guided ovum retrieval (TVUS-OR) in an IVF program from August 10, 1992, to April 30, 1993. Setting: A university-based tertiary referral hospital center was the setting. Participants and Methods: All patients (n=501) who underwent TVUS-OR were divided into three groups: (1) patients who underwent TVUS-OR on Monday; (2) patients who underwent retrieval on Tuesday, Wednesday, or Thursday; and (3) patients who underwent retrieval on Friday. All patients were induced by the same controlled ovarian hyperstimulation protocol, which consisted of a GnRH analogue “flare-up” followed by parenteral menotropins, after a scheduled oral contraceptive-induced menses. Patients and cycle characteristics in the three groups were compared and clinical outcome was evaluated. Results: The similarity of patients and cycle characteristics confirmed the uniformity of the three groups. No difference was found in any of the clinical outcomes. However, in the first half of the program, we revealed a trend in which patients at high risk for ovarian hyperstimulation syndrome, requiring freezing all embryos and not allowing transfer during the treatment cycle, occurred more commonly in women whose retrieval occurred on Monday. This trend disappeared in the second half of the analysis. Conclusions: In an in vitro fertilization program in which ovum retrievals occurred only on weekdays, no significant difference in outcome was found in patients undergoing ovum retrieval on Monday or Friday versus midweek. In addition to significant savings by eliminating weekend retrievals, IVF outcome is not compromised.

Serum progesterone concentrations on the day after human chorionic gonadotropin administration and progesterone/oocyte ratios predict in vitro fertilization/embryo transfer outcome

Purpose In gonadotropin-releasing hormone analogue-pretreated in vitro fertilization-embryo transfer cycles, pregnancy rates are inversely related to serum progesterone levels on the day of administration of human chorionic gonadotropin. The relationship of the progesterone concentration on other days in the periovulatory period to pregnancy rates in such cycles is little studied. We therefore retrospectively analyzed the relationship between progesterone concentrations on the day after human chorionic gonadotropin and pregnancy in 114 cycles, 28 and 23 of which produced clinical and ongoing/delivered pregnancies, respectively. To assess the effect of the extent of follicular luteinization on success, we also studied the relationship between the progesterone concentration per oocyte retrieved and pregnancy for the day of and day after human chorionic gonadotropin.Results Progesterone concentrations on the day after human chorionic gonadotropin were inversely associated with clinical pregnancy by multiple logistic regression analysis (P<0.05). Progesterone/oocyte ratios were inversely associated with clinical pregnancy (P<0.05) and ongoing/delivered pregnancy (P<0.02) for both the day of and the day after human chorionic gonadotropin.Conclusion The study results extend the window of time during which elevated progesterone concentration is associated with poor outcome to at least 2 days. This finding is consistent with hypothetical mechanisms attributing the link between progesterone concentration and outcome to either endometrial or follicle/oocyte events. The association of lack of follicular luteinization (low progesterone per oocyte ratios) and favorable outcome suggests a predominant effect of progesterone on follicle/oocyte quality. Further studies are needed to clarify the mechanisms underlying the association between progesterone and in vitro fertilization-embryo transfer outcome.     

Elevated serum progesterone level on the day of human chorionic gonadotropin administration does not adversely affect implantation rates after intracytoplasmic sperm injection and embryo transfer

Objective: To evaluate the association between serum P levels on the day of hCG administration and the outcome of intracytoplasmic sperm injection (ICSI).

Design: Retrospective case study.

Setting: Assisted reproduction unit of a tertiary care private hospital.

Patient(s): Nine hundred eleven ICSI cycles that proceeded to ET were studied.

Intervention(s): The decision to administer hCG was based on serum E₂ levels and follicle size. Serum P was measured from frozen sera obtained on the day of hCG administration. Cycles were stratified according to serum P levels of <0.9 ng/mL (n = 298) or ≥0.9 ng/mL (n = 613). This cutoff level was selected because it yielded the highest sensitivity and specificity according to a receiver operator characteristic curve.

Main Outcome Measure(s): Implantation and clinical pregnancy rates.

Result(s): In cycles with high serum P levels, more oocytes were retrieved and more embryos were available for transfer. Clinical pregnancy rates per ET in the low and high P groups were 36.9% and 45.4%, respectively (P<.05). The implantation rate per embryo was similar in the two groups (14.9% and 16.4%, respectively, in cycles with P levels <0.9 vs ≥0.9 ng/mL). Abortion rates were 22.7 and 25.8%, respectively (P>.05).

Conclusion(s): Our data showed no adverse effect of high serum P levels on the day of hCG administration on implantation rates after ICSI and ET.     

Controlled ovarian hyperstimulation interventions in infertile women aged 40 years or older undergoing in vitro fertilization

Background

The success of in vitro fertilization (IVF) treatment depends on adequate follicle recruitment following controlled ovarian hyperstimulation (COH). Women aged 40 years or older have a reduced ovarian reserve and various treatment protocols have been proposed that aim to increase their ovarian response.

Objectives

To compare the effectiveness of different COH treatment interventions in women undergoing IVF aged 40 years or older.

Search strategy

MEDLINE, the Cochrane Library, and the Chinese Biomedical database were searched for randomized controlled trials (RCTs).

Selection criteria

Only RCTs comparing one type of COH intervention with another in women undergoing IVF aged 40 years or older were included.

Data collection and analysis

Two authors independently searched the abstracts, identified relevant papers, assessed inclusion and trial quality, and extracted the relevant data.

Main results

Four trials involving 4 different comparison groups were included in the review and enrolled a total of 611 randomized subjects.

Conclusion

There was insufficient evidence to support the routine use of any particular COH intervention to manage infertile women aged 40 years or older undergoing IVF. More robust data from good quality RCTs with relevant outcomes are needed.
