‘IUD for men’ shows ‘positive’ results on par with vasectomy in early trials
June 9, 2025
As vasectomy interest piques, a new contraceptive for men is showing promising results in early trials.
Billed as an “IUD for men,” ADAM, a first-of-its-kind water-soluble hydrogel, was found to significantly reduce sperm motility and concentration similar to that of a vasectomy — the difference being that the effects of the hydrogel are reversible.
“We are thrilled to share these positive results which we believe take us one step closer to transforming the contraceptive landscape,” Kevin Eisenfrats, the co-founder and CEO of medical device company Contraline, said in a statement obtained by The Post.
The preliminary data, released on Thursday, “suggests that it is possible to achieve similar levels of efficacy as long-acting female contraceptives like IUDs,” or intrauterine devices, which are more than 99% effective he added.
“Ultimately, I’d like to make ADAM become a ‘no brainer’ for men when it comes to considering their options for contraception,” Eisenfrats said.
