Males just weren't born with the hormones to make lactate (usually). However, they do have nipples because they can provide sexual pleasure and stimulation.
Not all male mammals have nipples. I believe mice, rats, and horses are examples of mammals where the males do not have nipples. In fact, the platypus is a mammal, but it has pores and no nipples. Why this is, I do not know. I am trying to find out, but the information seems to be hard to come by.
Males have nipples because all embryos start off with the same basic body plan, which includes the development of nipples before gender is determined.
Men's nipples can lactate, but not under normal circumstances. This is often associated with the use of human growth hormone and can even be an indicator of cancer.
Males have nipples from an evolutionary perspective because nipples develop in embryos before the sex of the individual is determined. In mammals, including humans, nipples are a common feature that develops in all embryos, regardless of their eventual sex. This is because nipples are essential for feeding newborns, and it is more efficient for evolution to maintain nipples in both males and females rather than developing a separate system for males.
Yes it can. All dogs have nipples, even the males.
Inverted nipples are common and normal in males and females.

Yes, male animals can have nipples. Nipples are present in both male and female mammals, although they may not serve a functional purpose in males.
No boys don't, only females do cause female Guinea Pigs feed milk to their young ***Answer 2*** Like human males, yes Guinea Pig males also have nipples. But the nipples are totally useless. I know this because I've had male and female guineas. Its the same with pigs, dogs, goats. People often think my piglet is a girl, but he has his 'parts' Same with my cute goat kid. Dont think male horses have nipples though
Humans have nipples because they develop in the womb before the sex of the baby is determined. Both males and females start with nipples, but only females use them for breastfeeding.
Male nipples are considered vestigial because they do not have a specific function in the human body. They develop in the womb before the sex of the fetus is determined, so both males and females have nipples, but they serve no biological purpose in males.
Yes hairy nipples are normal for Men... but for girls they usually dont grow hair around the nipples.
