Abstract
Intramuscular administration of 250 mg testosterone oenanthate per week over a period of 21 weeks treatment rapidly and sustainedly suppressed serum LH as well as FSH levels in seven normal males, while serum testosterone rose by a factor of approximately two. These together with other data provide increasing evidence for a feedback control of FSH secretion by gonadal steroids in the male in addition to the already described but as yet undefined tubular testicular factor. Intramuskuläre Injektion von 250 mg Testosteronönanthat je Woche über 21 Wochen fürhrte zu einem raschen und anhaltenden Absinken der Serum-FSH- und -LH-Spiegel bei sieben männlichen Normalpersonen, während die Serum-Testosteronspiegel um etwa einen Faktor 2 anstiegen. Diese und frühere Ergebnisse verweisen auf eine zweifache Feedback-Hemmung der FSH-Sekretion beim Mann durch Gonadensteroide sowie einen bis heute nicht näher charakterisierten tubulären Hodenfaktor.Keywords
