Male Contraception

On male side reproductive gametes are the sperm cells. Those are produced inside the testicles. This process is called spermatogenesis; it has a duration of 75 days (approximatively 2 months and a half). The very fact is that testes are located outside the human body, in the scrotum, so they are maintained at a temperature of 34.4°C, lower than human body one (37.4°C). This condition is the essential to have spermatogenesis run ininterruptedly and to have continuous production of millions of sperm cells. When testicles temperature rises and is maintained for a long period (several days) at a higher temperature than human body one, spermatogenesis is turned on hold, and sperm cells production stops. If temperature is maintained higher for a longer period (4 to 6 weeks), numeration of sperm cells decrease from tens of million down to zero.

SpermaStop® is a heating pad conceived to be easy-to-use and go with. Once inserted in the special U-MAN Underwear® boxers scrotal pocket, SpermaStop® provides the scrotum with a soft warmth so testicles temperature rises by few degrees with no damageable effects (see temperature spreadsheet ).

SpermaStop® pad is very light and is not noticeable when worn on. It is linked to a thermoregulator located on U-MAN Underwear® boxers side so one can adjust temperature within a predefined temperature range.
By an application from just 2 hours a day SpermaStop® leads men to natural contraception state (no more sperm cells in semen = azoospermia) in few weeks (4 to 6 weeks). From there the sperm cells concentration level must be checked through a spermogram test in order to validate contraception state and to be free of usage of any other contraception means.

SpermaStop® is to be worn every day for about 2 hours time; however when contraception state is reached a lack of wearing SpermaStop® up to 3 or 4 days will not impact the male contraception. Indeed, from contraception state a man will have to wait 75 days (which is an entire spermatogenesis cycle) to recover his full fertilizing power. But as a matter a fact man who wants to ensure his contraception state must wear SpermaStop® on a regular daily basis. In case of multiple omissions it is suitable to establish sperm cells contraception level from 6 weeks after first omission. Meanwhile the man is still contracepted.

World Health Organization reports the following common data when it comes to man fertilization :
- Normal sperm cells concentration in men semen is range between 50 to 150 million.
- A natural fertilization may occur when sperm cells number is greater than 20 million.
- Infertility threshold for men is set to 15 million sperm cells.
- Male contraceptive threshold is set at 2.4 million.

SpermaStop® will bring you far more lower to this threshold, down to zero to ensure your contraception. SpermaStop® states a sperm cells numeration smaller than 1 million as requirement for your contraception.
At any time male may decide to recover full fertility in few months by quitting SpermaStop® application.

SpermaStop® is easy to wear through U-MAN Underwear® boxers . It’s simple, natural, efficient and reversible.

SpermaStop® fits all men. Be responsible. Just go for it !
