Abstract

This study explored the vulnerability of the ductus deferens due to mesh induced inflammation and shrinkage after hernia repair in the rodent model. Two commonly used types of hernioplastic implants (Proleneβ„’ and Vypro IIβ„’) were surgically wrapped around the ductus deferentes on both sides in 20 juvenile and 20 adult Sprague–Dawley rats. Twenty male rats underwent sham surgeries as controls. After 3 months, each male was mated with 2–3 adult females, which were subsequently sacrificed and oocytes or embryos were flushed and counted. Histochemical investigations of the implants and the ductus recovered surgically 4 weeks after implantation (one side) and after the fertility test (second side) were conducted. All groups exhibited 1–3 males with decreased or restricted fertility but there was no difference between groups. Histochemical analysis of the implants and the ductus recovered 4 weeks and 4 months after implantation revealed some sperm granulomes due to lesions of the spermatic cord caused by the implant in the Proleneβ„’ group. There was no inflammatory reaction in the mucosa or blockage of the spermatic cord visible. Both types of hernioplastic implants tested in this investigation do not give an indication of a negative influence on male fertility in juvenile or adult rats. Β© 2006 Wiley Periodicals, Inc.

The epididymal sperm gave higher rates, but ejaculated sperm were preferred because intra‐donor variation was lower than inter‐donor variation. A selected population of 14 ma

## Background: Feed restriction with its resultant body weight loss impacts the rodent estrous cycle; however, the manifestation of these changes in a regulatory study design has not been documented. this study reports the effects of feed restriction in the context of an fda regulatory submission.
