Effects of H(2)O(2) exposure on human sperm motility parameters, reactive oxygen species levels and nitric oxide levels.

abstract：:Sex hormones have been proposed as a possible risk factor for the development and growth of meningiomas. Hormonal therapy plays a fundamental role in the treatment of male-to-female transgenders and needs to be continued after sex reassignment surgery. Usually, this treatment leads to no adverse events; however, its i...
