Q: In case of hypo-oestrogenism, can an under-developed pelvis and long bones develop after treatment with hormones after the age of ossification?

A:No, after the centres close, you cannot grow, but I would protest about 157 cm being called short. 157 cm is average well nourished Indian woman's height. I am 158 cm, and definitely consider myself average height! However if you have been underoestrogenised (I wonder what is the basis for that statement), you need to make sure you take plenty of low fat milk, sun exposure of the skin, regular weight bearing exercise, and calcium and vitamin D supplements, else your bone density will soon become very low. The exercise will also help the PCOS and hirsutism by supplementing the effect of the drug, Diane.
