ON THE WAY
For those who aren't convinced a vasectomy is
right for them, a new male contraceptive jab
more effective than the Pill has been found to
prevent pregnancy for up to two years.
This injection, which blocks sperm from
leaving the body, is a breakthrough in the search
for a male equivalent of the Pill.
A World Health Organization investigation,
published in 2016, found that a male hormonal
contraceptive jab was as effective as the female Pill.
However, scientists are still working to overcome
the unwanted side-effects that are linked to
hormone-altering gels, pills and injections. These
include depression, acne and a soaring libido.
This product, called Vasalgel, is designed to
be reversible and had a 100% success rate in
monkeys. It works by injecting gel into the vas
deferens - the tube that transports sperm from
the testicles to the urethra - to block it.
Chair of the British Fertility Society Professor
Adam Balen said: 'This is a very interesting
technique that achieves a reversible "vasectomy"
by blocking the passage of sperm with a
substance that later can be flushed out.
'This has the potential for great promise as
a male contraceptive. It is essential to know
that the reversibility remains, though,
irrespective of the duration of use.'
Clinical trials are due to start this year.
HOPE FOR A
There is also hope that a male pill could be a
possibility in the future, after a new study on
mice found that certain proteins could block
sperm from being ejaculated.
In the study, male mice were bred to have
two genes that were 'turned off ', preventing the
production of two proteins that are associated
with sperm ejaculation.
The researchers found the technique had a
100% contraceptive success rate, and that there
were no negative effects on the sexual behaviour
of the mice or their sperm function.
Even though men produce around 300 million
sperm each time they ejaculate, this new
technique is very promising. The challenge for
researchers now is to find a drug capable of
disrupting the effects of these proteins that is also
safe and causes no, or minimal, side effects.
