Antiapoptotic effects of dehydroepiandrosterone on testicular torsion/detorsion in rats.

abstract：:Progressive Motility Sustaining Factor (PMSF) was isolated from human epididymides. PMSF could significantly improve progressive motility of oligozoospermic as well as asthenozoospermic semen. PMSF was found to increase cyclic AMP accumulation by the human spermatozoa indicating its possible mode of action. ...

abstract：:In mammals, pituitary control of spermatogenesis varies with age. In the rat, before puberty FSH is highly active whereas LH is not; after puberty it seems that LH alone is able to support spermatogenesis. The mode of action of hormones is discussed.
