Prolactin PROmotes LACTation i.e. it makes breasts produce milk.
A woman's breasts will continue to secrete milk as long as the woman continues to breast feed.
The breasts of a female primate's body contain the mammary glands, which secrete milk used to feed infants. Both men and women develop breasts from the same embryological tissues. However, at puberty, female sex hormones, mainly estrogen, promote breast development which does not occur in men. As a result, women's' breasts become far more prominent than those of men.
No, not unless she has also just given birth.
Yes. One characteristic unique to mammals is mammary glands. They are glands that secrete milk.
Age has nothing to do with when a female produces breast milk, and the only time a female has milk in her breasts is after giving birth. The first breast secretion after delivering is not milk, but a substance called "Colostrum", which is thought to have more of the vital nutrients and immune boosters than the breast milk itself has. The breasts will produce the colostrum for about a day, then they will begin producing milk. They will continue to produce milk for as long as the mother nurses, but when she stops nursing, the breasts stop producing milk.
, they just arent big at all. So must of the time their puppies die because the there is no milk.
The breasts are the upper part of the chest. The mammary glands give milk. Chickens have breasts and they don't give milk. Many sea mammals have nipples to give milk, but, they don't have breasts.
No it does not. But making milk yourself (lactation) does make your breasts bigger.
Yes there are chances of milk leaking when the breasts are fondled.
When you're pregnant, the milk isn't in your breasts yet. It's not until after you actually give birth that you get milk in your breasts. It follows colostrom, which is a natural antibiotic.
If a woman produce milk without being pregnant there is usually something wrong wiht the hormone levels and she needs to see a doctor.
