The better option is vasalgel.
Which is why it will never get approval
The video above dives into some of the challenges in developing and administering experimental drugs that can be used as birth control options for men as the main ones available to men are condoms and vasectomies which isn’t a lot. From the video summary on youtube:
“Condoms and vasectomies remain pretty much the extent of birth control options for people who produce sperm, and both have problems. So why is almost all hormonal birth control aimed at those with ovaries? There have been some successes targeting the biological feedback process for hormones that regulate new sperm production, but progress is slow.”
What doesn’t get mentioned about the clinical trials is that some of the men were infertile for a few years after they stopped taking birth control and in one case, he was rendered permanently infertile. Some cases resulted in low sperm count as well.
