| pubmed-article:2214463 | pubmed:abstractText | This study was designed to evaluate the functional changes of Sertoli cells following the administration of clomiphene citrate for male infertility. Sperm count and seminal transferrin level were measured before and after the treatment in 22 cases of oligozoospermia (sperm count: less than 20 X 10(6)/ml) and 14 cases of subnormal sperm count group (sperm count: 20-30 X 10(6)/ml). Clomiphene citrate was administered per os for more than 3 months consecutively in a dose of 25 mg/day. Seminal transferrin concentration increased more than 1.5 times compared with pre-treatment level in 6 cases (16.7%). Among these patients, sperm count markedly increased (20 X 10(6)/ml or more than the pre-treatment level) in 3 cases (50%) and slightly increased (10 X 10(6)/ml or more than pre-treatment) in 1 case (16.7%). In 30 cases, in which seminal transferrin level did not increase, sperm count markedly increased in 6 cases (20%) and slightly increased in 6 cases (20%). Thus, sperm count was improved more frequently in the cases in which seminal transferrin level remained elevated than the cases with no elevation of serum transferrin level. Serum FSH level of patients whose seminal transferrin level remained elevated after the treatment was significantly higher than that of patients with no elevation of serum transferrin level (mean +/- SD = 32.8 +/- 18.0 mIU/ml v.s. 14.4 +/- 11.7 mIU/ml, respectively). These data suggested that the activation of Sertoli cells may contribute to the increase of sperm count following the administration of clomiphene citrate and the elevated seminal transferrin secretion may be related to the increase of serum FSH level following this treatment. | lld:pubmed |
