Background: Oligoasthenospermia (OAS) is a condition characterized by low sperm count associated with low sperm motility. Medical treatment is not known in allopathic system for treatment of oligoasthenospermia. Homeopathic medicine is effective in more than 95% patients. Oxidative stress and decreased antioxidant levels have been projected as a potential factors involved in the pathophysiology...

Participation rates in epidemiologic studies on semen quality are generally very low, raising concerns as to the potential for selection bias. Since hormones both initiate and maintain spermatogenesis, they may serve as surrogates of semen quality in epidemiologic studies. For this reason, in the present study, we explored the influence and predictive ability of reproductive and thyroid hormone...

BACKGROUND Pregnancy rates with cooled equine semen can be unsatisfactory and show great variation. Information about first cycle pregnancy rates and pregnancy rates per cycle are often lacking from publicly available records. This retrospective cohort study was performed to evaluate the fertility of the Norwegian Coldblooded trotter. The aim of the study was to compare the breeding results aft...

This simulation study investigated the farm-level economic benefits of a genetic improvement scheme using artificial insemination (AI) with fresh ram semen in dairy sheep of the Chios breed in Greece. Data were collected from 67 farms associated with the Chios Sheep Breeders' Cooperative 'Macedonia', describing the percentage of ewes that would be artificially inseminated in the flock, pregnanc...

Introduction Primary breeders are currently faced with the same problem plaguing most animal industries, rising production costs. Labor, feed and energy costs are forcing primary breeders to consider more economical ways of maintaining gene pools. One way to reduce such costs is with the use of frozen semen. With frozen semen available from superior sires, primary breeders will have the tool to...
