Buy stock in a company that makes adult toys - a good investment opportunity.
Having sex with men just became too dangerous.
Also, reread Lysistrata.

The premise that the sperm-contributing partner always wants every egg-contributing partner they put sperm into to carry and deliver a baby ... is flawed.
In fact, I'd bet it's quite often that egg-contributing partners decide to HAVE an abortion ... based on the sperm-contributing partners reaction, esp if it's along the lines of "I really don't want you to have this baby, I will break up with you, I will not support the child, etc".
It should be 100% up to the person who's most at risk to make the decision, but the sperm-contributing partners feelings should be considered at least to some degree, and most of the time, I'd bet that's what happens.
Point is this ... there will be sperm-contributing partners who decide Post-Roe that it's not worth the potential risk as well.
And they also just might stock up on sex toys (for various reasons/applications), so overall, I like your investment idea
