Because the action under consideration is of a wholly different class than the others you mention.
For example, we regulate ivf, don't we? Why? Because the action undertaken has the ability to create new life.
The same is true of prostitution. The action undertaken is of a wholly different nature. Namely it can create people, which is different than any other labor.
Tolerating homosexual prostitution is actually more akin to your other analogies in that the action undertaken is not special. Although anal intercourse in general ought to be discouraged due to its deleterious health effects.
> For example, we regulate ivf, don't we? Why? Because the action undertaken has the ability to create new life. The same is true of prostitution.
No, we don't regulate it because it can create new life, we regulate it because it falls under healthcare for which doctors have a certain duty of care, and if IVF is done poorly it can cause all sorts of deleterious health effects for the mother and the implanted embryo. These considerations do not apply to prostitution since we have contraception and abortion.
Nonsense, we directly regulate even that which is not about health care. For example, most countries limit the amount of children a man can sire via sperm donation.

Whose burden falls solely on the women, and for which large portions of the population would object to the use of abortion as birth control. Even many pro-abortion people object to abortion's use as birth control, because they view abortion as justified murder, but murder nevertheless.
No, abortion is not murder because fetuses do not have personhood under the law. It's clear you don't really understand the legal precedents you're pontificating on so I don't really see this going anywhere.
