Progesterone Breast Growth . Men and women both have mammary glands so what's the difference well we saw that they'd have the ducts and the differences in size but the big difference is that when do mammary glands develop they typically develop during puberty so before puberty they they're pretty much identical in boys and girls before they develop they undergo puberty so they have the basic structure of undeveloped mammary gland but it's the changes in puberty that caused the development of mammary glands now what happens is that you have an increase in pro estrogens and progestogens in p when you start off the menstrual cycle and um and a girl has her first menarche her first menstrual cycle that's when you start to have that cyclical waves of estrogens and progesterone but what happens in male puberty is that you have increased levels of androgens you do have some estrogens and aromatase as well but this is things like you'll get increased high levels of andr...
Nipple discharge
Nipple discharge is usually harmless and does not signify anything seriously wrong. In fact, most women can squeeze some discharge out of their nipples, especially if they have had children in the past. This may be whitish or may be yellow-green or almost black.
On the other hand, nipple discharge can be a symptom of breast cancer, particularly if it is bloodstained. Therefore, you should definitely discuss any nipple discharge with your doctor. If you are a man, you should see your doctor straight away, because the usual cause is a tumour and you will need treatment.
What your doctor will do. Your doctor will check your medication, because some drugs can cause (non-bloody) nipple discharge. The most common culprits are:
- cimetidine (for stomach problems)
- oral contraceptives
- some antidepressants and other drugs for psychological problems
- domperidone (for nausea).
Your doctor will ask whether there is any possibility that you could be pregnant. Some women have nipple discharge very early in pregnancy. Your doctor will then examine your whole breast thoroughly (not just the nipple), to make sure you have no lumps.
Even if you have not noticed any blood, your doctor may ask you to try to squeeze a few drops out, and will test it for microscopic blood.
Each nipple has about 15–20 tiny pores on it. These pores are the openings of ducts that connect with the glandular tissue in the breast. You and your doctor should try to work out whether the discharge is coming from just one pore, or from several.
- The cause is very, very unlikely to be breast cancer if the discharge is coming from several pores, it does not contain any blood and you are under 50 years of age.
- If the discharge is bloodstained, or it is emerging from just one pore, your doctor will refer you to a hospital clinic for tests (such as ultrasound, mammography and looking at the discharge under the microscope) to make sure that breast cancer is not responsible.
- If the discharge is milky and coming from both breasts, your doctor can do a blood test to check for an imbalance of the hormone prolactin.
If all the tests are normal, you can stop worrying, but the discharge may st
ill bother you (perhaps soiling your clothes). A possible cause is some inflammation (mastitis) around the ducts. This is linked with smoking, and may improve if you stop smoking and avoid squeezing. A course of antibiotics may help.
It is possible to have an operation to close or remove the ducts that the discharge is coming from. This operation may not be a good idea for anyone who plans to become pregnant afterwards – depending on the number of ducts involved, it might make breastfeeding difficult and the breast might become congested.
