Improvement of spontaneous pregnancy rate after stopping gonadotropin therapy for anovulatory infertility.

In a prospective study, 140 patients with infertility because of ovulatory factors (group A) were followed up for 6 months after failure to achieve pregnancy using human menopausal gonadotropin (hMG) therapy. They included cases of oligomenorrhea, polycystic ovarian disease (PCOD), and hypogonadotropic amenorrhea. They were treated with hMG alone or in combination with clomiphene citrate or gonadotropin-releasing hormone agonist analog.

Dummy embryo transfer: a technique that minimizes the problems of embryo transfer and improves the pregnancy rate in human in vitro fertilization.

Three hundred thirty-five patients selected for in vitro fertilization (IVF) were randomly divided into two groups. Group A (n = 167) was subjected to dummy embryo transfer (ET) before the start of IVF treatment to choose the most suitable catheter for each patient. Group B (n = 168) started their IVF treatment without dummy ET.

Ultrasonically guided vaginal aspiration of ascites in the treatment of severe ovarian hyperstimulation syndrome.

This study included 11 cases of severe OHSS that were treated by transvaginal aspiration of the ascitic fluid guided by ultrasound. Immediate improvement of the symptoms and general condition as well as a significantly shorter hospital stay was noticed when compared with the control group. It is a safe and simple procedure that does not require anesthesia.

Transvaginal ultrasonic needle guided aspiration of pelvic inflammatory cystic masses before ovulation induction for in vitro fertilization.

Transvaginal aspiration of pelvic cystic inflammatory masses guided by a real time ultrasound vaginal transducer is described. The technique was successfully used in 32 patients to aspirate these masses before ovulation induction for in vitro fertilization (IVF). It is a safe and simple procedure that resulted in significantly higher ovarian response to stimulation for IVF, easier ultrasonic follow-up of the follicles, significant increase in the average number of oocytes per pick-up, and significant increase in the number of embryos per transfer when compared with the control group.
