In-vitro fertilization (IVF) is an effective infertility treatment for women with endometriosis, but most women need to undergo several cycles of treatment to become pregnant. This case-control study was designed to assess how consistently women with ovarian endometriosis respond to ovarian stimulation in consecutive treatment cycles compared to women with tubal infertility. We compared outcome measures in 40 women with a history of surgically confirmed ovarian endometriosis and 80 women with tubal infertility, all of whom had at least three IVF treatment cycles. The groups were matched for age and early follicular follicle stimulating hormone (FSH) concentration at their first IVF cycle. Outcome measures included number of follicles, number of oocytes, peak oestradiol concentration and number of FSH ampoules required per follicle. Cumulative pregnancy and live birth rates were calculated in both groups. The ovarian endometriosis group had a significantly poorer ovarian response and required significantly more ampoules of FSH per cycle, a difference that became greater with each subsequent cycle. However, cumulative pregnancy (63.3 versus 62.6% by fifth cycle) and live birth (46.8 versus 50.9% by fifth cycle) rates were similar in both groups. In conclusion, despite decreased ovarian response to FSH, ovarian endometriosis does not decrease the chances of successful IVF treatment.
体外受精(IVF)是治疗子宫内膜异位症妇女不孕症的有效方法,但大多数妇女需要经过几个周期的治疗才能怀孕。这项病例对照研究旨在评估卵巢子宫内膜异位症妇女与输卵管性不孕妇女相比,在连续治疗周期中对卵巢刺激反应的一致性。我们比较了 40 名经手术确诊患有卵巢子宫内膜异位症的妇女和 80 名输卵管性不孕妇女的结果。两组患者的年龄和首次试管婴儿周期的早期
卵泡刺激素(FSH)浓度相匹配。结果指标包括卵泡数、卵母细胞数、
雌二醇峰值浓度和每个卵泡所需的促卵泡激素安瓿数。两组的累积妊娠率和活产率均已计算。卵巢子宫内膜异位症组的卵巢反应明显较差,每个周期所需的 FSH 安瓿数也明显较多,这种差异随着以后每个周期的增加而增大。不过,两组的累积妊娠率(第五个周期为 63.3% 对 62.6%)和活产率(第五个周期为 46.8% 对 50.9%)相似。总之,尽管卵巢对 FSH 的反应降低,但卵巢子宫内膜异位症并不会降低试管婴儿治疗的成功率。
