SCIENTISTS have discovered an innovative contraceptive pill that makes men infertile within hours.
The one-off tablet works so quickly it could be taken as a last-minute contraceptive just a few hours before sex.
The revolutionary new male pill returns a man’s fertility to normal just hours after use.
It contains chemicals which prevent the ejaculation of sperm without affecting the intensity of the orgasm.
Satisfaction is not affected and the absence of hormones means that a man’s fertility should return by the following day.
It is believed to be more convenient than other male contraceptives being developed, which alter hormone levels and must be used over the long term.
Experts say a male pill could transform family planning roles by allowing couples to share the responsibility of contraception a burden that usually falls to women.
The pill has been developed by researchers at Kings College, London, who hope the pill will be on the market within five years.
Researcher Dr Christopher Smith said the pill could also be used as a long-term contraceptive without harming a man’s fertility.
“If the man was taking the pill for months and decided to come off it, we would expect his fertility to return just as quickly as if he had taken it on a one-off basis,” he said.
The discovery has interested Australian researchers who are working on a male pill of their own. Experts at the ANZAC Research Institute are perfecting hormone injections that block sperm production in much the same way as the female pill stops ovulation.
Initial tests of more than 1500 men showed that by injecting synthetic testosterone, hormone signals between the brain and the testes shut down to ultimately switch off sperm production.
The UK pill was inspired by medications used to treat schizophrenia and high blood pressure that prevent ejaculation.
But these drugs also produce side effects such as dizziness and drowsiness. After isolating how the medication stops sperm production, the researchers set about creating the tablets without the side effects.
King’s College researchers have completed laboratory tests and hope to start human trials shortly.
