Eugenol Prevents Sodium Nitrate-induced Altered Antioxidant Status of Spermatozoa: An In Vitro Study
Abstract: Background: High level of nitrate (NO3) induces oxidative stress which affects the male and female reproductive system. In this regard, there is a great concern for the prevention of NO3-induced oxidative stress in the reproductive system by using herbal products. Eugenol is one such natural product found in clove extracted from cloves (Syzygium aromaticum) and is known for its antioxidant, anti-nociceptive, anti-inflammatory, and anti-apoptotic properties. Aim and Objectives: The present …

Chemotaxis: role in egg-sperm interaction and its evaluation
Abstract: Communication between spermatozoa and egg before contact by chemotaxis is prevalent throughout the animal kingdom. In most animal species, the prospects of the spermatozoa coming in contact with eggs are very slim in the absence of some guidance mechanism usually chemical in nature that has been acquired gradually. Such chemical guidance, sperm chemotaxis, is now recognized in many marine invertebrates, fish, amphibians, and a few mammals including humans. This suggests …

Toxicological Effect of Khat (Catha edulis) in Male Reproductive System
Abstract: In this project paper, databases such as Pubmed, Medline, Hinary and Google search, were systematically searched for literature on the different aspects of Catha edulis (Khat) to synthesize, review, and present various research publications on the toxicology to document the effect of khat consumption on the histology and function of male reproductive system. The euphoric effects have been demonstrated to arise from the main constituent, (-)-S cathinone. Detailed studies on …

¬¬¬Lycopene Protects Testes and Epididymal Sperm in BPA Exposed Adult Sprague-Dawley Rats
Abstract: Bisphenol A (BPA) is ubiquitous and persistent environmental contaminant. Previous studies proved that BPA disrupt hypothalamic–pituitary–gonadal axis and oxidative balance. Numerous studies have clearly been reported that oxidative stress leads to male infertility by affecting testes and spermatozoa. On the other hand, lycopene has beneficial role on testes and spermatozoa by reducing the oxidative stress. Therefore, this study was conducted to delineate the protective role of lycopene by acting against …

Significance of Artificial Insemination in Poultry
Abstract: AbstractArtificial insemination (AI) involves the deposition of semen into female reproductive tract manually. It starts from the collection of the semen from the male and its evaluation in terms of motility, viability and concentration followed by its deposition into female reproductive tract. Sexual maturity in both male and female bird occurs at 18 weeks of age. One ejaculate of a male can cover up 20 female birds by using AI. …

RsaI polymorphisms of ER-β and Idiopathic Male Infertility
Abstract: Purpose: Study on association between estrogen receptor gene polymorphism and male infertility has been interested, but highly specific genetic markers have been reported to be variable according to regions and nations. Herein we studied to figure out whether ERβ gene1082 G>A polymorphism could influence on sperm indices or not.Method: We dealt with 100 Korean patients with idiopathic male infertility diagnosed at our university hospital as a study group and 127 …

The Effect of Vitamin C on the Reproductive Functions of Paraquat Intoxicated Male Albino Rats (Rattus norvegicus)
Abstract: Paraquat (PQ) is a bipyridylium herbicide applied around trees in Orchids and between crop rows to control broad-leaved and grassy weeds. Its oxidation results in the formation of superoxides and supernitrite species which causes damage to cellular components. Studies have implicated PQ as one of the pesticides that contributes to the reduction in male reproductive functions in humans and animals during exposure. This study, therefore, determined the antioxidant effect vitamin …
