D ) Loss of body fat
Hey, what do you think of these sex hormones are made of......either LH, FSH or estrogen.
They are bunch of cholesterol fats. They all possess basic rim of cholesterol skeleton common to all these sex hormones.
Without greasy fat, no sex hormones....
Simple as that....
Exercise induced amenorrhea presents generally in a young patient who prior to the onset of amenorrhea has had multiple metabolic and physiologic events that have inhibited the normal pulsality of LH and FSH secretion. These events are most likely subtle and do not manifest themselves until these insults are repeated and chronic and eventually menses stop. Subtle buffers that protect the reproductive system are affected: the most obvious is adequate weight or, as suggested by recent work, adequate body fat and leptin levels. The patients with exercise or weight loss related amenorrhea invariably are below or near so-called "ideal weight" and generally have low body fat and body mass index. They may have lost significant weight while exercising and may have obsessive eating problems including low fat and avoidance of red meat and all desserts. The diagnosis can be pinpointed in the competitive athlete with low gonadotropins, particularly low LH, normal prolactin, a negative pregnancy test, and no signs of androgenization such as acne, hair growth, or history of menarchial onset of irregular menses associated with signs of androgen excess. The typical patient with this problem will resist changing her behavior, particularly gaining weight or decreasing her exercise load. This is particularly true of the ballet dancer or competitive athlete. However, a change in eating habits, exercise patterns, and an increase in weight is the most effective method of reversing the problem.
