ABSTRACT

Hypogonadotropic hypogonadism (HH) is a rare disease in which medical treatment has a high success rate to achieve fertility. This study aimed to analyze the efficacy of hormone replacement therapy and determine predictive factors for successful spermatogenesis and spontaneous pregnancy in patients with idiopathic HH. A total of 112 patients with low testosterone (T), luteinizing hormone (LH) and follicle-stimulating hormone (FSH), and normal prolactin levels were diagnosed with HH and administered LH and FSH analogs as hormone replacement therapy. During treatment, 96 (85.7%) patients had sperm present in ejaculate samples. Among these patients, 72 were married and wanted a child. Of these 72 patients, 48 (66.7%) of couples had pregnancies from natural conception. After initiation of treatment, the mean time for the appearance of sperm in semen was 9.48 months. There were no significant differences between baseline FSH, T, and LH levels; however, older age, larger testicular size, and low rate of undescended testes were favorable factors for successful spermatogenesis. Larger testicular size and older age were also the main predictive factors for natural conception. We found that patients with undescended testes had a younger age, smaller testes, and lower T levels compared with patients exhibiting descended testes. The rate of sperm found in the ejaculate was not significantly decreased in patients with undescended compared with descended testis (73.7% vs 87.6%, P = 0.261). The medical approach for males with HH and azoospermia provides a successful treatment modality in regard to successful spermatogenesis and achievement of pregnancy.

ABSTRACT

Objective To analyse the clinical significance of LHRH exciting test in the differential diagnosis of constitutional delayed puberty (CDP) and hypogonadotropic hypogonadism (HH). Methods Eighty-one cases from 1982 to 1998 were investigated and followed up. They were all at genital stage Ⅰ. After injection of 100 ?g LHRH, the blood samples (3 ml) were taken at -15, 0, 15, 30, 45, 60, 90 and 120 min. The serum LH and FSH levels were determined by radioimmunoassay. Then they were followed up every 3-24 months. After they received LHRH exciting test, they were followed up until over 18 years old. According to their puberty development status, they were divided into 3 groups, normal group (n=34),CDP group (n=16) and HH group (n=31),andthemeanage,whenthey received LHRH exciting test, was (10.2?0.9, range 9-14) years, (16.0?1.0, range 14-18) years and (17.1?1.4, range 16-22) years respectively. Results There were no significant differences in serum LH baseline level and peak time in normal, CDP and HH groups, but the serum LH peak level, LH increment (peak LH level minus baseline LH level), LH increment ratio (peak level/baseline level of LH) and the area under LH curve (AUC LH ) of normal group were significantly higher than those of CDP group and HH group (all P
