The Olympics' current transgender policy doesn't require a man go through any "treatments and procedures" to compete in women's events under the current "transgender policy." A male athlete is eligible to compete in women's Olympics under the following two conditions:

2.1. The athlete has declared that her gender identity is female. The declaration cannot be changed, for sporting purposes, for a minimum of four years.

2.2. The athlete must demonstrate that her total testosterone level in serum has been below 10 nmol/L for at least 12 months prior to her first competition (with the requirement for any longer period to be based on a confidential case-by-case evaluation, considering whether or not 12 months is a sufficient length of time to minimize any advantage in women’s competition).

Note that declaration about gender identity doesn't have to be legally-binding one. Nor does it have to be backed up by official ID documents like passport. A man's "female gender identity" also need be declared "for sporting purposes" only.

Plus, he has to intend to keep it, or say he plans to keep it, for only four years - years that don't have to be consecutive, nor do they have to coincide with, occur around the time as, the male athlete is competing in women's Olympics. A man could say he had a "female gender identity" for several years when he was a little boy so that time should count toward the four years total, or he intends to declare a female identity when he's 60 to 64, so that should do the trick. There's not going to be any verification or even an attempt to verify - it's all on the honor system, so who could tell if he's being truthful or bullshitting?

Note also that there's no requirement that the male athlete be taking estrogen or any T suppressants. The 10 nmol/L limit for testosterone is within what World Athletics considers the normal male range - 7.7-29.0 nmol/L - so it would be easy for a lot of guys to meet that condition without taking any drugs. Many guys have T of that level naturally.
