Impotence secondary to postpuberal hypogonadism.

Area of Science:

• Endocrinology
• Reproductive Medicine
• Andrology

Background:

• Secondary impotence coeundi presents a diagnostic challenge.
• Normal pubertal development and prior fertility contrast with current erectile dysfunction.
• Hormonal imbalances, specifically follicle-stimulating hormone (FSH) and luteinizing hormone (LH) deficits, were suspected.

Purpose of the Study:

• To investigate the hormonal basis of secondary impotence in patients with normal pubertal development.
• To evaluate the efficacy of gonadotropin therapy in restoring sexual potency.

Main Methods:

• Studied four male patients presenting with secondary impotence.
• Assessed basal levels of FSH, LH, testosterone, ACTH, TSH, and performed metopirone test and PBI.
• Administered human chorionic gonadotropin (HCG) and gonadotropin-releasing hormone (Gn-RH) stimulation tests.
• Analyzed spermiograms for semen parameters.

Main Results:

• Consistent basal deficits in FSH, LH, and testosterone were observed.
• HCG stimulation yielded positive results, while Gn-RH stimulation did not alter basal levels.
• Spermiograms revealed oligoasthenozoospermia.
• Sexual potency was rapidly restored following HCG treatment.

Conclusions:

• The findings suggest a selective, idiopathic hypothalamic or pituitary deficit of FSH and LH with postpubertal onset.
• HCG therapy is an effective treatment for restoring sexual potency in such cases.
• Further research into the etiology of idiopathic hypogonadotropic hypogonadism is warranted.
