When we talk about sub-fertile we're meaning that perhaps there is some sperm, but there's less of it or it's…

reader to the bizarre and coveted substance that catalyzed the rapid expansion of the whaling industry. Spermaceti is a waxy, oil-like substance produced in the spermaceti organ in the skull of the sperm whale. Originating from the spermaceti-organ, the fluid is located in the cranial cavity of the sperm whale and occupies a major part of the skull, holding up to 1,900 litres of spermaceti. Since the spermaceti organ, a fluid-filled sac, transforms after the death of the whale, scientists have…

exposure to a calcium ionphore alone was sufficient to overcome upstream hyperpolarization and PKA pathway defects in infertile mouse models that normally occur prior to a intracellular calcium increase in functional and sufficiently capacitated mouse sperm cells. Additionally, they examined Catsper knocked out mice to determine if a transient calcium increase in these mice was also sufficient to overcome capacitation and fertility defects discovered in early experiments by Ren, D et al. in…

situation after six months. Infertility may describe both a woman who is unable to conceive as well as a woman who is unable to carry a pregnancy to full term.

because it is a genetic disorder. Men with klinefelter syndrome have one Y and two X chromosomes (What causes male infertility?, n.d.). This affects men physically by causing the testicles to be peanut-sized. Klinefelter's syndrome like other affect sperm production and delivery (What causes male infertility?, n.d.). Diseases can also become obtained sexually. STDs like gonorrhea and chlamydia cause infertility by blocking the epididymis or tubes (What causes male infertility?, n.d.). Most…
