introduction: date palm gemmule has been used in traditional medicine to improve the semen quality and treat infertility. their components remedies those are rich of antioxidant and vitamins can influence spermatogenesis. the aim of this project was to evaluate the effects of date palm gommule water/alcoholic extract on reproductive tissues, sex hormone and sperm quality of rat. methods: sevent...

background: there is growing concern that occupational, environmental and lifestyle factors adversely affect male reproductive health. fumaria parviflora lam. is being used traditionally in persian folk medicine to cure various ailments and has been supposed to have fertility-enhancing properties. objective: a dose-response study was designed to assess effects of f. parviflora ethanolic leaves ...

Modern societal pressures and expectations over the past several decades have resulted in the tendency for couples to delay conception. While women experience a notable decrease in oocyte production in their late thirties, the effect of age on spermatogenesis is less well described. While there are no known limits to the age at which men can father children, the effects of advanced paternal age...

BACKGROUND AND AIMS There are anecdotal reports that men who wear (Scottish) kilts have better sperm quality and better fertility. But how much is true? Total sperm count and sperm concentration reflect semen quality and male reproductive potential. It has been proven that changes in the scrotal temperature affect spermatogenesis. We can at least affirm that clothing increases the scrotal tempe...

Mapping epigenetic modifications and identifying their roles in the regulation of spermatogenesis and embryogenesis are essential for gaining fundamental medical understandings and for clinical applications. More and more evidence has shown that specific epigenetic modifications are established during spermatogenesis, which will be transferred into oocyte via fertilisation, and play an importan...

Testicular cell apoptosis is associated with impaired spermatogenesis. It has been reported that Asiatic acid (AA) may suppress apoptosis. However, little is known about the effect of AA on high-fat diet (HFD)-induced impairment of spermatogenesis. The aim of the present study was to determine whether AA protects against HFD-induced impairment of spermatogenesis. Sprague-Dawley rats were random...

Several gene expressions are related to the success of spermatogenesis. Protamine plays an important role in sperm DNA packaging, spermatogenesis, and quality. This study aimed isolate RNA from spermatozoa determine expression profiles protamine 1 (PRM1) 2 (PRM2). Six Pasundan bulls aged 5-8 years with a body weight 380 kg-430 kg were used for this study. The classified into group A (70%-79%) B...
