Many antimalarial remedies are known for reproductive toxicity in male. Also, several plants to have antifertility action both sexes. The aim of this study is evaluate the effect ethanol extract Senna occidentalis (L.) Link Leguminosae leaf (EESO) on male parameters such as sperm count, motility, morphology and histology testes Wistar rats by employing standard procedures. (50% ethanol) was ora...

background: about 90% of the world�s contraceptive users are women. this gender-based usage has occurred due to the emphasis of family planning programs and contraception research. condom, vasectomy and withdrawal are the only male contraception devices available with less assurance for men. for new male contraceptive to have an impact, they must be acceptable to both men and women, as well as ...

Hamster spermatozoa were isolated from the caput, corpus and cauda epididymidis. They were observed in culture medium at 37 degrees C with a phase-contrast microscope and their motility recorded cinematographically. About 20 p. 100 of the caput epididymidis spermatozoa were motile and moved in a confined space with no forward progression. 30 p. 100 of the corpus epididymidis spermatozoa were mo...

background: a bulk of contraceptives on the market is women-oriented today. the aim of this study was to investigate the effect of a medicinal herb, acacia nilotica on various parameters of male fertility using a rat model. methods: male wistar rats (n=40) were randomly divided in to two groups. one group received acacia nilotica, while the other acted as controls. ten animals from each group w...

Concentrations of mono- and divalent cations in the testis, three different regions of the epididymis and the vas deferens of lizard, M. carinata were determined. The concentrations of Na+, K+ and Ca2+ increased gradually from testis to vas deferens. However, no significant variation in the levels of Mg2+ was observed between testis and anterior epididymis, and between posterior epididymis and ...

AIM To investigate the effect of epidermal growth factor (EGF) on the sperm content and motility of the varicocelized rats. METHODS Forty-eight male Wistar rats were randomly divided into five groups. Experimental varicocele was induced by partial ligation of the left renal vein in the varicocele, the varicocele repair, the varicocele with EGF and the varicocele repair with EGF groups, wherea...

Binder of SPerm (BSP) proteins are a family of proteins expressed exclusively in the male reproductive tract (seminal vesicles or epididymis) of several mammalian species. They are known to promote capacitation, a sperm maturation step essential for fertilization. Our recent studies have shown that in human, the Binder of SPerm Homolog 1 (BSPH1) is expressed solely in epididymal tissues. The go...

The process of gametogenesis in the male occurs within the seminiferous tubules of the testes, resulting in the production of sperm. Many factors like Drugs, chemotherapy and toxins can generate harmful effect on spermatogenesis and affect sperm normal production. Gentamycin is a synthetic antibacterial agent belonging to the family of amino glycoside. Antioxidants scavengers of free radicals c...

background: ubiquitin, an 8.5 kda peptide that marks other proteins for proteasomal degradation, tags defective sperm dur­ing epididymal passage. thus, sperm ubiquitination is a universal marker for sperm defects and can be used as a sperm func­tion test. the objective of the present study was to examine the relationships between sperm ubiquiti­nation and clinical se­men parameters, using simpl...

The effect of aqueous leaf extract of Azadirachta indica (Neem) on reproduction was studied on male albino rats. The study was divided into three groups of six animals each. The first group (I) received distilled water serve as control. The second and third groups (II and III) of animals were administered the aqueous leaf extract daily at 250mg/kg body wt., and 350mg/kg body wt., respectively f...
