In many civilized parts of the world, a female employee getting pregnant will mean disruption during the pregnancy to accommodate doctor's visits and health issues, and then months of paid leave PLUS having to pay to backfill their position with a temp, plus the costs of recruiting and ramping up said temp.
That's a huge hit for an early stage startup to take.
There are regular doctor's visits during pregnancy, yes, but that's a few hours a month. Surely even the smallest startups can absorb that kind of "disruption".

I work for a small startup - fewer than 20 employees - and two of our team members are married. They had a baby and were both out for month (the mom took more time after that), and everything continued to function just fine because we'd planned for it. And if we needed them, they were just an email or text away.
Finally, parents can be some of the most efficient workers on a team, and are great candidates for startups. They are experienced in time management and balancing multiple tasks and stakeholders.

That's all I have to say on this matter. I will not be posting further.
