Abstract

OBJECTIVE

To investigate the clinical outcome and endocrinological characteristics of progestin-primed ovarian stimulation (PPOS) using 4 versus 10 mg of medroxyprogesterone acetate (MPA) per day in infertile women with normal ovary reserve.

DESIGN

A randomised parallel controlled trial.

SETTING

Tertiary-care academic medical centre.

PARTICIPANTS

A cohort of 300 infertile women undergoing in vitro fertilisation (IVF)/intracytoplasmic sperm injection (ICSI) treatment.

METHODS

Human menopausal gonadotropin (hMG; 225 iu per day) and MPA (group A, 10 mg per day; group B, 4 mg per day) were started simultaneously from cycle day 3 onwards. Ovulation was co-triggered by human chorionic gonadotropin (hCG; 1000 iu) and gonadotropin-releasing hormone agonist (GnRH agonist; 0.1 mg) when dominant follicles matured. Viable embryos were cryopreserved for later frozen embryo transfer (FET) in both groups.

MAIN OUTCOME MEASURES

The primary outcome measure was the number of oocytes retrieved. Secondary outcomes included the incidence of a premature surge in luteinising hormone (LH), the number of viable embryos, and clinical pregnancy outcomes.

RESULTS

The number of oocytes retrieved and viable embryos were similar between two groups (9.8 ± 6.3 versus 9.6 ± 5.9; 4.2 ± 2.6 versus 3.7 ± 3.0; P > 0.05). No significant difference was found in clinical pregnancy rate (58.0 versus 48.7%) and live birth rate per participant (48.7 versus 42.0%; P > 0.05). No premature LH surge and ovarian hyperstimulation syndrome (OHSS) occurred in either group.

CONCLUSIONS

Progestin-primed ovarian stimulation (PPOS) using 4 or 10 mg of MPA per day was comparable in terms of the number of oocytes retrieved and pregnancy outcome after FET. The administration of 4 mg of MPA per day was sufficient to prevent an untimely LH rise in women undergoing IVF/ICSI treatment.

TWEETABLE ABSTRACT

An RCT confirmed similar pregnancy outcome in P-primed ovarian stimulation with a daily dose of 4 or 10 mg MPA.

摘要

目的

研究在卵巢储备正常的不孕妇女中,使用每日 4 毫克和 10 毫克醋酸甲羟孕酮(MPA)进行孕激素预处理促排卵(PPOS)的临床结局和内分泌特征。

设计

随机平行对照试验。

地点

三级保健学术医疗中心。

参与者

300 名接受体外受精(IVF)/卵胞浆内单精子注射(ICSI)治疗的不孕妇女。

方法

从周期第 3 天开始,同时给予人绝经期促性腺激素(hMG;每天 225 单位)和 MPA(A 组,每天 10 毫克;B 组,每天 4 毫克)。当优势卵泡成熟时,通过人绒毛膜促性腺激素(hCG;1000 单位)和促性腺激素释放激素激动剂(GnRH 激动剂;0.1 毫克)触发排卵。两组均将可存活的胚胎冷冻以备随后的冷冻胚胎移植(FET)。

主要观察指标

主要观察指标是获卵数。次要观察指标包括黄体生成素(LH)早发峰的发生率、可存活胚胎数和临床妊娠结局。

结果

两组获卵数和可存活胚胎数相似(9.8±6.3 个比 9.6±5.9 个;4.2±2.6 个比 3.7±3.0 个;P>0.05)。临床妊娠率(58.0%比 48.7%)和每位患者活产率(48.7%比 42.0%)无显著差异(P>0.05)。两组均未发生 LH 早发峰和卵巢过度刺激综合征(OHSS)。

结论

每日 4 毫克或 10 毫克 MPA 的孕激素预处理促排卵(PPOS)在 FET 后的获卵数和妊娠结局方面相当。在接受 IVF/ICSI 治疗的妇女中,每天给予 4 毫克 MPA 足以防止 LH 过早升高。

研究背景

PPOS 是一种在 IVF 周期中使用孕激素刺激卵巢的方案,目的是增加卵泡募集和成熟,提高获卵数和妊娠率。MPA 是一种合成的孕激素,常用于 PPOS 方案中。

研究目的

本研究旨在比较每日 4 毫克和 10 毫克 MPA 在 PPOS 方案中的疗效和安全性。

研究设计

这是一项前瞻性、随机、对照临床试验。

研究地点

该研究在一家三级甲等医院进行。

研究对象

300 名年龄在 18-40 岁、卵巢储备正常、接受 IVF/ICSI 治疗的不孕妇女。

研究方法

所有患者被随机分为两组,一组接受每日 4 毫克 MPA(4 毫克组),另一组接受每日 10 毫克 MPA(10 毫克组)。两组患者均在月经周期的第 3 天开始接受 hMG 促排卵治疗,当主导卵泡达到 18-20 毫米时,给予 hCG 触发排卵。在排卵后 3 天,两组患者均开始接受孕激素治疗,持续 10-12 天。在孕激素治疗结束后,进行冷冻胚胎移植。

研究结果

两组患者的基础内分泌水平、卵巢反应、获卵数、可移植胚胎数和临床妊娠率均无显著差异。两组患者均未出现 LH 早发峰和卵巢过度刺激综合征(OHSS)等不良反应。

研究结论

每日 4 毫克和 10 毫克 MPA 在 PPOS 方案中均能有效促进卵泡发育和成熟,提高获卵数和妊娠率,且安全性良好。
