In male contraceptive trials, approximately half of normal men become azoospermic on high dosages of testosterone enanthate (TE), whereas the other half of men become severely oligozoospermic. To determine whether sperm function is reduced in men with severe oligozoospermia induced by TE, we studied
This study was undertaken to assess the fertilizing capacity (sperm function) of residual spermatozoa produced by groups of men (n = 7) rendered oligozoospermic by treatment with weekly intramuscular injection of 50 or 100 mg testosterone enanthate (TE). The treatment was continued for 6 months and
In normal men, chronic testosterone (T) administration results in negative feedback suppression of gonadotropin and sperm production. However, azoospermia is achieved in only 50-70% of men treated with high dosages of T. Furthermore, the relative sensitivity of LH and FSH secretion to chronic
