You are focusing solely on "young women".

The thread is about a teenage girl scheduled to have a cosmetic bilateral mastectomy, so yeah the focus is on young female people.

Vasectomies on young men are a non-issue for you?

Verypeak mentioned sterilization of young women. You then made the leap that she was referring to tubal ligation, which you further jumped to link and equate to vasectomy.

Whilst on the surface these might appear to be analogous procedures, in fact they are not. The only reason a male might want to have vasectomy is to make it impossible to impregnate a female person. Males don't have vasectomies as a way to relieve recurrent or chronic pelvic pain, to deal with recurrent blood loss that has made them anemic, or to stave off a physical condition/experience that might kill them.

By contrast, girls or women might want or need a tubal ligation (or other method of sterilization) to prevent excruciating pain and regular extreme blood loss from heavy periods and ovulation AND to prevent becoming impregnated by a male person, which can lead to situations where the female person's survival is put at risk and her future life options become much narrowed.

Many males have fainted, vomited and experienced extreme anxiety when their female partners were in labor and giving birth. But no male has ever died from labor or childbirth, suffered severe tearing to the genitals or damage to the pelvic nerves, needed to have their vulvas or bellies split open, required a blood transfusion, or suffered a life-threatening infection from/after giving birth.

Similarly, many males have gained weight and gotten moody and broody when their female partners have gone through pregnancies. But as far as I know, as a result of pregnancy no males have experienced physically-caused nausea or vomiting (aka the misnomered "morning sickness"), allergies or hives, high blood pressure, piles, reflux/indigestion, excessive fatigue or insomnia, liver pain and other forms of physical discomfort, pre-eclampsia, gestational diabetes, etc. Nor do males experience the extreme hormonal fluctuations and states that can wreak havoc on women's mental health during pregnancy and in the months/years after giving birth. And after birth, males don't have to deal with issues like engorged breasts, mastitis or urinary incontinence, either.

The experience and consequences of impregnating for males and becoming impregnated for females are so vastly different that they are not even comparable. So you are right: drawing a parallel between vasectomies and procedures on women that can leave us sterile is a bad analogy.
