| Popis: | An assessment of the effectiveness of synthetic luteinizing hormone-releasing hormone (LH-RH) in the treatment of idiopathic normogonadotropic oligoasthenospermia was made in 21 subjects selected on the basis of at least three previous sperm counts; a history of long-standing infertility; normal urinary gonadotropin excretion; normal serum levels of luteinizing hormone, follicle-stimulating hormone, and testosterone; and lack of any evidence of other clinical, endocrine, vascular, infectious, and/or urologic involvement. On testicular biopsy, 14 patients showed hypospermatogenesis or arrest up to the spermatid stage (group 1), while the remaining 7 had more severe spermatogenetic disorders (group 2). Libido and/or potency were previously unaltered in all subjects. Five patients in group 1 and five patients in group 2 received intramuscular injection of 100 to 500 mug of LH-RH daily for no less than 60 days (long-term treatment); the remainder received the drug for 30-day periods, with 30-day intervals (short-term treatment). Qualitative and quantitative assessment of the results during and after treatment showed frank improvement in spermatozoal concentration, vitality, and motility in group 1 patients, particularly in those undergoing long-term treatment (three of five patients under these conditions were able to impregnate their wives). The long-term regimen also resulted in predomantly qualitative improvements in group 2 (one of five patients impregnated his wife). The short-term regimen was less effective. Improvements under either regimen usually occurred at the end of, or after, treatment. Six of seven patients in group 1 who were followed for a long period retained values above preliminary values for 90 to 150 days after the drug was discontinued. Increased libido and potency were spontaneously reported by 15 patients, 20 to 30 days after the start of administration of synthetic LH-RH. |
