Correction lang sa TS. Both guys and gals have testosterone and estrogen hormones. Men have higher testosterone hormones than women while they have higher estrogen hormones than men.
Here's my advice:
My girlfriend is using diane pills (birth control pills) for health purposes coz of her menstruation that occurs twice a month, but not often. Her doctor adviced her to use pills para ma.correct ang iyang menstruation. My GOD! her breast grew significantly. Looks damn solid and yummy. Hehehehehehe! She's a nurse by the way so I trust when she said it was because of the pills.
Another factor pud sa pills kay you can control your menstrual period whenever you want them to come. You'll get less body hair too, same with my gf. This is because the pills supplements you with extra estrogen which makes you more woman.
Overall, pills are AWESOME!!
Important Note:
My gf said that some pills(katong mga baratuhon) can cause cervical cancer. Diane pills is proven safe. And also, ang diane dili makapatambok dili pareha sa mga baratuhon nga pills. It cost about 500+ if my memory serves me right.
