To investigate the IVF outcome for patients with endometriosis.
Design
Meta-analysis.
Setting
Academic research center.
PATIENT(S): A MEDLINE search and review of the literature were performed. Patients were classified by level of endometriosis, and controls were classified according to the indication for IVF.
INTERVENTION(S): Bivariate analysis and multivariate logistic regression was used to estimate overall effect and control for confounding.
MAIN OUTCOME MEASURE(S): Pregnancy rates, fertilization rate, implantation rates, and numbers of oocytes retrieved.
RESULT(S): Twenty-two published studies were included in the overall analysis. The chance of achieving pregnancy was significantly lower for endometriosis patients (odds ratio, 0.56; 95% confidence interval, 0.44-0.70) when compared with tubal factor controls. Multivariate analysis also demonstrated a decrease in fertilization and implantation rates, and a significant decrease in the number of oocytes retrieved for endometriosis patients. Pregnancy rates for women with severe endometriosis were significantly lower than for women with mild disease (odds ratio, 0.60; 95% confidence interval, 0.42-0.87).
CONCLUSION(S): Patients with endometriosis-associated infertility undergoing IVF respond with significantly decreased levels of all markers of reproductive process, resulting in a pregnancy rate that is almost one half that of women with other indications for IVF. These data suggest that the effect of endometriosis is not exclusively on the receptivity of the endometrium but also on the development of the oocyte and embryo.

Endometriosis is a common finding among women with infertility, and women who are diagnosed with endometriosis are almost twice as likely to experience infertility. Mechanisms by which endometriosis causes infertility remain poorly understood. In this review, we evaluate the current literature on the impact of endometriosis on oocyte and embryo quality. The presence of endometriosis evidently reduces ovarian reserve, oocyte quality, and embryo quality; however, this does not appear to translate to a clear clinical impact. Analysis of data from large assisted reproduction technology registries has shown that women with endometriosis have a lower oocyte yield but no reduction in reproductive outcomes. There is a need for future studies in the form of well-designed randomized controlled trials to further evaluate the role of surgical and medical treatment options in women with endometriosis undergoing assisted conception.
To analyze IVF outcomes in patients with a history of one or more elevations in basal FSH who have a normal basal FSH at the start of their IVF cycle, compared with the general IVF population.
Retrospective clinical study.
University hospital. PATIENT(S): General IVF patient population. INTERVENTION(S): Patients received standard IVF gonadotropin protocols, oocyte retrieval, and embryo transfer. MAIN OUTCOME MEASURE(S): Oocyte yield, fertilization, implantation, clinical pregnancy, and cancellation rate. RESULT(S): Oocyte yields were lower in patients with a history of elevated basal FSH, for all age groups, and showed an age-dependent decline in all patients. Over the age of 40 years, both implantation and clinical pregnancy rates were lower in these patients, with no significant difference observed in patients under the age of 40 years. No pregnancies were observed in patients with a history of three or more elevated FSH levels, regardless of age. CONCLUSION(S): A history of elevated basal FSH levels in patients under the age of 40 years predicts a lower oocyte yield in IVF cycles with normal basal FSH levels but does not translate to either lower pregnancy or implantation rates. Patients aged >40 years with prior elevations in basal FSH levels have both compromised ovarian response and compromised embryo quality relative to those with normal FSH levels, as illustrated by lower oocyte yield, higher cancellation rates, and lower implantation and pregnancy rates.

To investigate differences in immature oocyte maturation, fertilization, and pregnancy rates among women with unstimulated normal ovaries, polycystic ovaries (PCOs), or PCOS. Prospective observational study. University fertility clinic. PATIENT(S): One hundred forty-four women undergoing 180 in vitro oocyte maturation treatment cycles. INTERVENTION(S): Transvaginal immature oocyte recovery from unstimulated ovaries 36 hours after hCG priming. In vitro oocyte maturation and fertilization. Fresh embryo transfer. MAIN OUTCOME MEASURE(S): Immature oocytes collected, metaphase II oocytes, and embryos produced. Implantation and pregnancy rates. RESULT(S): The overall oocyte maturation and fertilization rates attained were 80.3% (1,222 of 1,522) and 76.5% (935 of 1,222), respectively. Significantly fewer immature oocytes were retrieved from normal ovaries (5.1 +/- 3.7) compared with the PCO (10.0 +/- 5.1) or PCOS (11.3 +/- 9.0) groups. Fertilization and cleavage rates were comparable among the three groups. The implantation, pregnancy, and live birth rates per transfer for normal ovaries were 1.5%, 4.0%, and 2.0%, respectively; for PCOs 8.9%, 23.1%, 17.3%, respectively; and for women with PCOS 9.6%, 29.9%, and 14.9%, respectively. CONCLUSION(S): Immature oocytes retrieved from normal ovaries, PCOs, or women with PCOS, when using hCG priming before oocyte retrieval, have a similarly high maturation, fertilization, and cleavage potential. In vitro maturation is a useful treatment option, particularly for women with PCOs.
To evaluate the influence of female age on clomiphene citrate (CC) with IUI therapy and to compare the efficacy of this therapy between patients with ovulatory and anovulatory infertility. A university fertility clinic. Six hundred sixty-four CC with IUI cycles from 290 women aged 22 to 48 years. Cumulative and clinical pregnancy rates (PRs). Both cumulative and clinical PRs declined substantially in women > 35 years when compared with those < or = 35 years. In addition, no difference in these parameters was noted between patients with ovulatory and anovulatory infertility diagnoses. The vast majority of pregnancies occurred within the first four treatment cycles, irrespective of age or ovulatory versus anovulatory infertility diagnoses. The age-related decline in clinical PR is most rapid beginning at the age of 35 years. For any given age group, CC with IUI therapy has similar cumulative and clinical PRs for both ovulatory and anovulatory infertility diagnoses. This therapy usually should not extend beyond four cycles. Couples should be counseled about the dramatic fall in PRs occurring beyond the age of 35 years.
