Male Baldness Info

I am very much obese and have all the horrible side effects of PCOS: the excess facial/body hair, some male pattern baldness, darkened skin on the back of my neck, underarms, inner thighs, acne, etc. I also have what is known as Metabolic Syndrome. If I was to become a healthy weight for my age (27), would this cure or drastically reduce the effects of my PCOS or am I doomed to suffer with this condition for the rest of my life?

i have read that by weightlifting , it raises testosterone levels which in turn speeds up male pattern baldness. if you weighttlift for 45 minutes the testosterone in your body gets raised 25%.
so with this in mind, if i weight lift for only 20 minutes, will this raise my testosterone levels enough to speed up male pattern baldness
thanx in advance
