[49] [28] High dosages of testosterone that result in supraphysiological levels of testosterone (> 50 ng/dL) significantly increase sexual desire in women, with levels of testosterone of 80 to 150 ng/dL "slightly" increasing sexual desire. [49] [28] Further higher dosages of testosterone may result in greater effects on sexual desire in women.

The volume of the semen sample (must be more than 1.5 ml), approximate number of total sperm cells, sperm motility/forward progression, and % of sperm with normal morphology are measured. It is possible to have hyperspermia (high volume more than 6 ml) or Hypospermia (low volume less than 0.5 ml).
Poor diet can otherwise lead to oxidative stress, which causes sperm damage, leading to lower testicular volume and lower sperm quality. Ensuring enough vitamin and mineral intake might also be recommended, since omega-3 fatty acids, antioxidant vitamins, zinc, and selenium might help reduce the damage by oxidative stress and reduce inflammation.
Semen can be tested for sperm count, sperm motility, sperm morphology, pH, volume, fructose content, and acrosome activity. Checks are also made to identify undescended testicles and retrograde ejaculation, along with medical history, such as cancer treatment, radiation, drug use, etc.
