Australian researchers are working on a new injectable male contraceptive in a world-first trial.
7News reports trials are underway at Melbourne's Epworth Hospital for the groundbreaking injectable male contraception that works as a temporary vasectomy.
It's reported a hydrogel is injected into the vas deferens, the tubes that carry sperm, to block the sperm from travelling to the testes - acting like a temporary vasectomy.
Once the hydrogel is injected, it dissolves after about two years and the procedure can then be repeated.
Four men aged between 30 and 45 have already undergone the 30-minute procedure, with 21 other men expected to have the hydrogel injected too.
7News reports researchers have seen high demand for the temporary contraceptive which could be available by the end of 2025.
Study principal investigator Professor Nathan Lawrentschuk told 7News the implant "could be a game-changer".
"The three-year study will investigate whether the hydrogel is successful as a non-permanent, long-lasting male contraceptive."
He added the men involved in the study will undergo regular health checks and provide semen samples for three years.
