Purpose: Intrauterine human chorionic gonadotropin (hCG) infusion at the time of embryo transfer (ET) has resulted in controversial results. We evaluated the effects of intrauterine infusion of a small volume of hCG at the time of ET in fresh and frozen-thawed cycles.

Methods: Infertile women scheduled for ET with either fresh or frozen-thawed cycles were enrolled and randomized into two groups (n = 100 each): an hCG group, who received 500 IU of hCG in 10 µL culture medium infused into the uterine cavity using a soft catheter 4 min before ET; and a control group, who received 10 µL of culture medium alone by the same technique.

Background/aims: Follicle-stimulating hormone (FSH) priming has been studied in in vitro matured oocytes for oocyte maturation rate, embryo quality, and pregnancy rate with discouraging results. This study aimed to initiate FSH stimulation later, i.e.

The pathogenesis of endometriosis remains poorly understood at least in part because early stages of the disease process are difficult to investigate. Previous studies have proposed a three-dimensional fibrin matrix culture model to study human endometriosis. We examined the ultrastructural features of the endometriosis in this model and assessed the effect of a progestin on endometrial outgrowth and apoptosis in this culture system.

The activated androgen receptor (AR) in decidualizing human endometrial stromal cells (HESCs) regulates genes involved in cytoskeletal organization, cell motility, and cell cycle progression. Androgens also enhance the secretion of prolactin, a widely used marker of decidualized HESCs. The purpose of the present study was to investigate the direct effects of androgens on the ultrastructural changes associated with decidual transformation of HESCs.

Objectives: To evaluate the efficacy and level of satisfaction from mefenamic acid and hyoscine when used for pain relief during saline infusion sonohysterography.

Study Design: In this double blind randomized controlled trial, 141 nulliparous women were allocated to receive 500 mg of mefenamic acid, 10mg of hyoscine or a placebo, which was packed in the same outer capsule. Saline infusion sonohysterography (SIS) was performed 30 min later by one operator.

Objective: To determine the effect of 200 μg of intravenous nitroglycerin in the release of retained placenta by controlled cord traction.

Methods: In this randomized controlled study, 40 women with a placenta retained for 30 minutes received intravenously 200 μg of nitroglycerin or a normal saline solution before umbilical cord traction was initiated. The rates of successful removal of the retained placenta in the study (n=20) and control (n=20) groups were compared, as were blood pressure, pulse rate, blood loss, and adverse effects.
