Quote from Cecil:
“In other words, nipples are just one of those sexually neutral pieces of equipment, like arms or brains, that humans get regardless of sex.”
Nipples are as sexually neutral as the uterus. The uterus is for having babies, the nipples are for nursing babies. And a non-functioning nipple is hardly “equipment.”
Quote from Cecil:
“One interesting consequence of the developmental set-up just described is that during the very early stages of fetal life, before the sex hormones have had a chance to do their stuff, all humans are basically bisexual.”
Other sources have said that before sex hormones have had a chance to do there stuff that the embryo isn’t bisexual but"following a female template."
Quote from Cecil:
“Trouble is, male nipples are hardly vestigial. They’re full-sized and fully equipped with blood vessels, nerves, and all the usual appurtenances of functioning organs.”

Mens nipples do not function. They may have helped breast feed in the past, but that definitely doesn’t go on now.
I think this is a good definition of what vestigial is. It doesn’t matter if it has nerves or blood vessels. Our wisdom teeth are thought to be vestigial since our jaws are thought to have grown to small over time to accommodate them. But they still have all the usually things that our other teeth have.
The pinky toe has been said to be vestigial too since we don’t climb trees anymore. Sure it has nerves and blood vessels but we don’t need them to walk. And as anyone can see, land animals that aren’t climbing trees tend to have four toes, not five. And in places where people don’t wear shoes a lot of the time they are missing there pinky toes. So not only do they not help our mobility but they can cause trouble. You’ll also notice on a dog and alike that there fifth digit has moved up there leg, it’s slowely disappearing because it has no use. But the vestigial dew claw still has blood vessels, nerves, skin, hair, etc…
