Pregnancy outcome of assisted reproductive technology cycle in patients with hypogonadotropic hypogonadism.

CONTEXT: Ovulation induction in patients with hypogonadotropic hypogonadism (HH) is a challenge to the treating physician. The threshold for ovarian response in HH may differ substantially from that of normal patients. To reach that threshold levels of follicle stimulating hormone, in a step-up protocol longer duration of stimulation is required in some cases so as to prevent multiple pregnancy and to eliminate the risk of ovarian hyperstimulation syndrome.

AIM: To evaluate the duration of stimulation, quality of oocytes, and embryo, and the pregnancy outcome in the assisted reproductive technology (ART) cycles in patients with HH.

MATERIALS AND METHODS: Over the period of 4 years, we had 14 patients with HH in whom 21 cycles of ovulation induction were done. Of these 7 patients underwent oocyte retrieval and intracytoplasmic sperm injection (ICSI). We present a retrospective study of these 7 patients who underwent ART to evaluate the duration of stimulation, quality of oocytes and embryo, and the pregnancy outcome.

RESULTS: In the study group on ovulation induction with gonadotropins, only one patient had the duration of stimulation of the standard 12 days, the remaining 6 patients took ≥12 days to respond to stimulation (maxium being 54 days). Mean ET in these patients was 8.9 mm. Six patients had >70% good quality MII oocytes. One patient responded poorly and had only 2 good quality MII oocytes (50%). After ICSI procedure, resultant embryos were of grade 1 and 2 in all the patients irrespective of the duration of stimulation. Fertilization rate in these patients was 85% (except in one 50% fertilization rate), and the cumulative pregnancy rate was 68.6%.

CONCLUSION: In the patients with HH the quality of oocytes and embryos, and the pregnancy rate is not affected even if the duration of stimulation is prolonged.
