SPERMATOGENESIS AND FERTILIZATION IN ELDERLY MEN

Ok, Elvan

Old age leads to a series of changes both in male and female organisms and increasing male age is considered to affect spermatogenesis and fertilization as well. Recently, the upward shift in paternal age has accelerated research on the effects of advanced male age. Most studies maintain that semen parameters; in particular, sperm mobility, semen volume, and the number of sperms with normal morphology are adversely affected by the increase in male age, while sperm concentration remains unchanged. However, these age-dependent charges are at a moderate level and it is still uncertain whether thi ...Daha fazlası

Objective: The aim of this study was to enlighten both the testicular histology and the genetic aspects of the apoptotic process. Thus an experimental study was designed with a model of unilateral vasectomy. Methods: Twenty-two adult male rats were used and 4 main groups were formed. The first (A), the second (B), the third (C), and the fourth group (D) consisted of 4, 4, 4 and 10 rats respectively. Rats in group A had sham operation while rats in other groups (B, C, D) underwent left vasectomy operation including binding of ductus deferens with a 3/0 silk and cutting a minimum of 1 cm part wh ...Daha fazlası
