Sperm count is a measure of fertility. For sperm cells, conception is a race to fertilise an ovum and greater numbers put the odds on your side. These sperm cells are produced within the tiny tubes of the testes from germ cells, and sertoli cells foster their growth and development. But the story of sperm begins in the brain. The pituitary gland within the brain releases luteinizing hormone LH and follicle-stimulating hormone FSH to trigger sperm production in the testes.
The Catsper channel and its roles in male fertility: a systematic review
Effects of Panax ginseng, zearalenol, and estradiol on sperm function
Reproductive Biology and Endocrinology volume 15 , Article number: 65 Cite this article. Metrics details. All of these physiological events require calcium entry into sperm cells. Furthermore, the Catsper channel is regulated by some physiological stimulants, such as progesterone, cyclic nucleotides e. In addition, the Catsper channel may be a potential target for male infertility treatment or contraception. This review will focus on the structure, functions, regulation mechanisms and medicinal targets of the Catsper channel. Mature mammalian sperm execute many important physiological processes, such as sperm hyperactivation, chemotaxis towards the egg, capacitation and acrosome reaction, before even entering the female reproductive tract and contacting eggs for fertilization.

Panax ginseng exerts multiple activities in biological systems and is classified as an adaptogen. Zearalenol is a potent mycoestrogen that may be present in herbs and crops arising from contamination or endophytic association.
