Green tea decrease sperm levels

Sperm cells are highly sensitive to reactive oxygen species ROS , which are produced during cellular oxidation. In normal cell biology, ROS levels increase with a decreasing antioxidant response, resulting in oxidative stress which threatens sperm biology. Oxidative stress has numerous effects, including increased apoptosis, reduced motion parameters, and reduced sperm integrity. In this regard, green tea polyphenols GrTPs have been reported to possess properties that may increase the quality of male and female gametes, mostly via the capability of catechins to reduce ROS production. GrTPs have antioxidant properties that improve major semen parameters, such as sperm concentration, motility, morphology, DNA damage, fertility rate, and gamete quality. These unique properties of green tea catechins could improve reproductive health and represent an important study area.

Antioxidants may help men with fertility problems, study reveals | Science | The Guardian

Introduction: Testicular tissue is part of the reproductive system that some mineral compounds such as cadmium chloride CdCl 2 destroy. Green tea Camellia sinensis extract can reduce the tissue damage caused by toxins due to its antioxidant properties. The aim of this study was to evaluate the effect of green tea extract on sperm quality in cadmium chloride toxicity. Materials and Methods: In the present study, male Wistar rats were allotted randomly into four groups, namely control group C , CdCl 2 1. CdCl 2 was injected intraperitoneally 1. At 13, 25 and 49 days after treatment, the rats were euthanized and the reproductive organs testes, epididymis were excised and used for sperm analysis and histo-morphometric examinations.

Green tea extract shows potential sperm benefits: Lab study

Couples who struggle to have a baby may be more likely to conceive if the man takes antioxidants, scientists say. The finding emerged from a major review of medical studies into the impact of antioxidant supplements on couples being treated at fertility clinics. A variety of antioxidants, including vitamin E, zinc and magnesium, appeared to improve couples' chances of conceiving if the fertility problem was known to lie with the man. The Cochrane Library, which conducts "gold standard" systematic reviews of research, focused on 34 medical trials involving 2, couples. Most of the men in the trials had either low sperm counts or sperm that were poor swimmers.

Recent studies suggest drinking several cups of green tea a day can not only improve your health but also increase fertility in both women and men. Green tea is the perfect drink of choice containing polyphenols and hypoxanthine rich anti-oxidants , the two main ingredients that can double the chances of conceiving by helping an egg to mature properly and preparing your body. Packed with antioxidants such as EGCG, green tea may boost fertility by reducing the formation of free radicals and preventing DNA damage to cells including sperm and eggs. Green tea also contains L-theanine which enhances metabolic rate to regulate weight, supports healthy insulin levels and reduces anxiety.
