Yes, sometimes it takes time, like in Japan the birth control pill ..
"Campaigners here joke that it took the country 30 years to approve the contraceptive or birth control pill, but just six months to approve the Viagra pill for male impotence. Both became available in 1999, but the latter came first."
Well you have to take birth control constantly and a lot of very young women end up having it. You could easily wipe out a generation of fertile women if you didn’t do it correctly. On the flip side, old men (usually) that sometimes need to use a pill doesn’t seem all that dangerous.
