At this point in time the level of the hormone higher than the average norm in 1,5-2,5 times. Knowing the current levels of FSH in the body, specialists can determine the cause of hormone deficiency.

LH is responsible for what

Luteinizing hormone is produced by the pituitary gland with follicle-stimulating. It is responsible for the stimulation of testosterone synthesis and estrogen.

The normal FSH is increased in 2-2,5 times, however this phenomenon is quite natural. After a few days there comes the second, luteal phase of the menstrual cycle. The concentration of follicle-stimulating hormone decreases to normal. At this time, with the same intensity increases contents of LH in blood.

Each of these parameters is taken into account when planning a pregnancy, but much more important is the ratio between them. To a full of puberty hormones LH and FSH in the blood is the same. Upon completion of the formation of the reproductive system LH, the female grows a half to two times. The allowable ratio of these hormones acquires a value of 1.5-2 to 1.
