The objectives were to: 1) determine if im treatments of Lutalyse expedited the training of sexually inexperienced boars for semen collection and increased spermatozoal output, and 2) determine the effects of dietary L-carnitine supplementation on boar libido, semen quality, sperm production, and maintenance of sperm motility during liquid storage. Experiment 1 utilized lean-type, terminal-line...

Oxymycterus rufus is a wild rodent that inhabits one of the world hotspots known as the Atlantic Rain Forest in Brazil. Due to the lack of reproductive data regarding such species, the present study aimed to describe O. rufus spermatogenic process through morphometrical and stereological analyses. To do so, testicular fragments of five sexually mature males were routinely processed for light an...

BACKGROUND Reverse pharmacology for drug development has been highly productive and cost-effective in recent past as it is based on the documented therapeutic effects of plants in ancient texts. Afrodet Plus(®) is formulated for the treatment of male infertility, which contains ancient herbo-minerals. Its efficacy and safety are validated through this animal study in reverse pharmacology mode. ...

Background: Diabetes mellitus as a chronic disease can cause fertility problems in male human population. In fact, it exerts sever damages in testicular tissue and subsequently reduces total number of normal sperms and semen volume. Therefore, this study is designed to evaluate the protective effect of Equisetum arvense extract on sperm quality, DNA damage and maturation in diabetic male mice. ...

Background: Diabetes mellitus, a condition of chronic hyperglycemia, represents one of the greatest concerns to modern global health. Diabetes is a serious metabolic disorders with numerous complications. It is well known that, elevation of blood glucose levels leads to structural and functional changes in various target tissues and organs. The objective of the present study was to verify if th...

Background: Prolonged alcohol abuse in men can cause testosterone deficiency and shrinkage of the testicles (testicular atrophy). This can lead to impotence, sterility and ‘feminisation’. When alcohol is broken down in the body, it may also interfere with normal sperm structure and movement. This study was designed to determine the effects of administration of alcohol on sperm quality, sperm ma...

Human sperm count studies, historic dietary iodination, and an animal model where neonatal goitrogen administration causes unprecedented testis enlargement, together suggest an hypothesis relevant to the postulated fall in human sperm counts. We present the hypothesis with a supporting study extending the model to include iodine deficiency. In a one-generation rat reproduction study, dams were ...

The non-hormonal contraceptive, named RISUG (an acronym for Reversible Inhibition of Sperm under Guidance) has expected to provide a valuable addition to the current options of male contraception. The present study was conducted to determine the reproductive functional success, safety of vas occlusion by RISUG, and its reversal by dimethylsulphoxide (DMSO), followed by multigenerational (F1-F3)...

OBJECTIVE To examine the relationship between sperm reactive oxygen species (ROS) production and sperm morphology in a group of infertile men and healthy fertile donors. DESIGN A prospective clinical study. SETTING Male infertility clinic, Glickman Urological Institute, The Cleveland Clinic Foundation, Cleveland, Ohio, and the Reproductive Medicine Unit, Liverpool Women's Hospital, United K...
