A recent study in the Journal of Human Reproduction, June 2012, showed that wearing tight fitting underwear is associated with a lower motile sperm concentration - A. C. Povey et al. This study also showed no correlation between sperm quality and obesity, smoking, or drinking, which is an unfortunate message to give dad's to be, as there is absolutely no doubt that the health of the father plays a role in the health of the off-spring, long term.

Daily ejaculation (or more!) is important when trying to optimize sperm. A Spanish study published in the November 2011 edition of Fertility & Sterility (the bible of reproductive health peer reviewed medical publications) states: "Overall, if oxidative stress in the epididymis increases SDF (sperm DNA fragmentation), then the more prolonged the storage time in epididymis the higher will be the increase in SDF. Thus, reducing the storage time should help to prevent the extratesticular increase in SDF." Translation, ejaculate more often.

Testosterone is a sex hormone in men required to be able to produce sperm. It is produced primarily in the testis and is especially abundant in young men. As we age, testosterone levels naturally decline. Statistically, at the age of 50, the decline becomes more rapid and gives way to male menopause (andropause).

Peritoneal fluid is a liquid that is made in the abdominal cavity to lubricate the surface of the tissue that lines the abdominal wall and pelvic cavity and covers most of the organs in the abdomen. This abdominal fluid in women with Endometriosis contains various biochemicals with a host of anti-fertility effects. Prostaglandins, cytokines, autoantibodies, reactive oxygen radicals, over-expression of nerve growth factors, vascular endothelial growth factors, angiogenic factors and more can all lead to;
