The male contraceptive injection is here but there are side effects

And they're the same ones women have been suffering from for years.

A male contraceptive injection has been created by researchers that can suppress the sperm count in testicles, but the production has been put on hold after participants suffered severe side effects.

More than 250 men between the ages of 18 and 45 took part in the research, and had all been in monogamous relationships with female partners between the ages of 18 and 38 for at least one year.

The participants received testosterone/progestin injections every eight weeks and over the course of the study only four pregnancies occurred.

Yet despite the effective results, a safety review committee decided to stop the study early after the participants frequently experienced mood swings, depression, muscle pain and acne.

Of course, women have been suffering from these side effects (and more) since the pill was first introduced in the 1960s. Though recent research has shown there are some contraceptive pill benefits, so it’s not all bad.

In an interview with Chicago TribuneDr. Mario Festin of the World Health Organisation said: ‘We have to continue searching for or investigating the right drugs, and their combinations, with the highest efficacy and safety, and acceptability with the least side effects.’

‘Giving testosterone alone will suppress sperm production,’ he explained. ‘However, the additional administration of another hormone, usually a progestin, helps increase the suppression of sperm production to lower levels in more numbers of men.’

‘The safety committee felt that the number of side effects, particularly the mood changes, were too many,’ Dr. Festin addded. ‘The study had already proven that the drug combination could already produce the desired effect of lower sperm counts, and the unfavourable side effects may outweigh any further findings.’

When asked, more than 75% of the men that took part in the research said they would be willing to use the male contraceptive injection in the future, despite these side effects.

No further development is in the pipe lines for the development of this contraceptive jab. Though we still have the possibility of the male pill.
