Invasive Male Contraception Techniques May Destroy Fertility Potential


With grave consequences for both humans and wildlife, scientific research from around the world has already established that a host of common man-made chemicals is feminizing males of every class of vertebrate animals, from fish to mammals, including people. New methods of man-made contraception such as ultrasound blasters and male injections are adding fuel to this fire further degrading the potential of human fertility.

The Testicle Ultrasound Blaster

Scientists have discovered that ultrasound could work as a form of contraception for men. They claim a one-of blast of ultrasound energy waves to the testes would halt sperm production for up to six months, according to research by the University of North Carolina.

Dr James Tsuruta, a scientist involved in the research, says: ‘This could provide men with up to six months of reliable, low-cost, non-hormonal contraception from a single round of treatment.’

Research has been done on rats, but human trials may start next year. Concerns have been raised as to whether it will affect a man’s fertility long term.

"The type of ultrasonic waves that will used here are a form of mechanical energy that may disrupt sperm production indefninitely," said Dr. Norman Kelly who runs his own fertility clinic on the outskirts of Berkshire, England. "No long-term testing will likely take place to examine the consquences, and consequently such a technology may likely cause permanent damage to the testes."

The Male Pill

British researchers are developing a male pill that prevents sperm from being released on ejaculation.

The pill uses compounds found in blood pressure and anti-psychotic medications used in the Sixties, which produced the side-effect of ‘dry ejaculation’.

They paralyse certain muscles in the male reproductive system, causing a temporary block of the release of semen while having no adverse effects on libido, sexual performance or sensation — so the man still has an orgasm, but produces no fluid.

Professor John Guillebaud, emeritus professor of family planning and reproductive health at University College London, says: ‘This method has the potential to be a “pre-coital” pill, possibly working at full efficacy in about two to four hours after it is swallowed.’

"The side effects of the compounds being used to cause 'dry ejaculations' are known, and they certainly would not be desirable for healthy young men seeking to prevent unwanted pregnancies," stated Dr. Kelly.

Male Injection


A testosterone injection given to men once a month could soon be a new form of male contraception equal to the female Pill or condoms.

The jab, given in the buttocks, works by reducing two regulatory brain chemicals — follicle-stimulating hormone and luteinizing hormone — which in turn temporarily block sperm production.

Trials in China found only one man in 100 fathered a child while on the injections. If condoms are used correctly, they are 98 per cent effective.

"Luteinizing hormone is responsible for the production of testosterone in the testes and disruptions in its release at the pituitary gland may dramatically affect a mans ability to produce testosterone and achieve or maintain an erection," added Dr. Kelly. Common side-effects would include mood swings and a lower sex drive.

Although many of the contraceptive techniques above are still in their preliminary stages of development, many fertility specialists are not only questioning the "when" but are also beginning to question "why?"

If the potential to harm future fertility and libido is there, why even bring such concepts to the market place?
