In men, low testosterone levels in the body can be supplemented by hormone replacement with testosterone. Testosterone replacement therapy can be prescribed as an intramuscular injection usually given on a biweekly basis; as a patch or gel placed on the skin, or as putty that is applied to the gums of the mouth. Each of the treatments has its risks and benefits. The decision as to which form of testosterone to use depends upon the clinical situation. Discussions between the patient and health care professional often helps decide which medication to use.
In the United States there are currently no preparations that are FDA approved for testosterone replacement for women.
Great article, well written and god conclusions of collected data.
How ever I am still curious if creating a “shortage” of sperm and decrease of testosterone by cycles of repeated ejaculations during a short period of time, maybe during the course of hours followed by “rest-days” if that over time would provoke the body to produce more Testosterone and sperm in a response to “progressive overload”.
Since this is the way the body handles a lot other things that challenges it´s system with everything from resistance-training, “repeated skin-abrasion”, bacteria and even some toxins.
While testosterone is typically seen as a "male" hormone, it's also present (albeit in much smaller amounts) in women. However, between 4-7% of American women produce too much testosterone in their ovaries, which usually leads to a condition called polycystic ovary syndrome.  Too much testosterone in women can lead to infertility due to lack of ovulation, as well as some embarrassing symptoms like acne, a deepening voice and facial hair growth. Reducing testosterone levels in women is often accomplished with medication, although dietary change can make a positive impact also.
