We usually face puberty at the age of 12 or 13. It all starts with the production of progesterone from the ovaries. Also along with this testosterone is produced. This testosterone acts on the granulosa cells which help in the development of the female gamete. The presence of FSH ( Follicle Stimulating Hormone), increase the aromatase activity of these cells. The aromatase help in the biosynthesis of estrogen hormone. The testosterone in females is used for 2 purposes. One purpose is for production of estradiol for the development of bones , growth, breast development, increase in fat composition, growth of uterus, increase in the thickness of endometrium present in the walls of the vagina and widening of the pelvis region. The second purpose is responsibility for the changes in females like development of pubic hair, acne , odour etc. But also it is made sure that the testosterone is not produced in excess. With the increase in estradiol and other processes , maturation is reached at a point where the female starts to ovulate along with the production of leutenizing hormone. The growth hormone is also produced during this time period which is produced till the end of puberty which is marked by the complete development of the ends of the bone due to estradiol. Though we may face many menstrual problems , we have to take good care of ourselves at these times and do everything necessary for it. No change's in our body should be taken for granted as it defines who we are and our beauty.
