Gelatin condom for women in 3-5 years, page 1

The gel is liquid as long as it is in contact with the acidity that is normal in a vagina, but will turn solid when it encounters semen, which is slightly alkaline. Any particles wider than 50 nanometres – including sperm, HIV and other viruses such as the herpes virus and the papilloma virus, which causes cervical cancer – are trapped, so the gel could double up as both a protectant and a contraceptive.

That's amazing! You would think there would be more developments in a product niche nearly everyone buys into at some point, but nothing much seems to change. You have your birth control pill, male and female condom, female implant or depot shot... that's about it besides surgery in terms of effective methods of contraception. And if you aren't thinking ahead, only standard condoms and diaphragms are releasable.

Finally contraception is moving out of the 20th century, personally I'm excited to see how this turns out.
