Comparison of different starting gonadotropin doses (50, 75 and 100 IU daily) for ovulation induction combined with intrauterine insemination.

Purpose: To prevent multiple pregnancies the goal of ovulation induction by gonadotropins is to achieve only mono-follicular development. The most important issue is therefore to determine the starting dose. The aim of this study is to compare three different starting doses of follitropin beta to assess the lowest effective dose.

[Comparison of human chorionic gonadotropin (Pregnyl 10 000 IU i.m.) versus GnRH agonist (triptorelin 0,2 mg s.c.) for final oocytes maturation in the same egg donors--clinical and embryological characteristics].

Objective: To compare clinical and embryological characteristics in donor cycles triggered for final oocytes maturation with Pregnyl 10 000 IU i.m. versus triptorelin 0.

[Clinical effects of recombinant versus urinary gonadotropins in ovulation induction].

Objective: To present an overview of trials and discussion focused on the clinical characteristics of recombinant gonadotropins compared with urinary ones in ovulation induction.

Subject: Review article.

Setting: Sanatorium Pronatal, Prague.

[Single embryo transfer does not compromise the pregnancy rate in patients with good IVF/ICSI prognosis].

Objective: Twin pregnancy is perceived as a suboptimal result of an IVF/ICSI cycle. The most effective way to reduce the number of twins in IVF/ICSI program is a single embryo transfer. The aim of our study was to compare the efficiency of elective single embryo transfer (eSET) and double embryo transfer (DET) in the couples with a very good prognosis of IVF/ICSI.

[Ovarian hypertimulation syndrome: a review].

Objective: Discuss prevalence, risk factors, pathophysiology, symptoms, complications and therapy of OHSS.

Design: A review article.

Setting: Department of Obstetrics and Gynaecology, 1st Faculty of Medicine and General faculty Hospital, Charles University, Prague.
