Facioscapulohumeral muscular dystrophy (FSH), also known as Landouzy-Dejerine disease, which begins in late childhood to early adulthood and affects both men and women, causing weakness in the muscles of the face, shoulders, and upper arms.
In girls, the increase in LH and FSH hormones in the bloodstream stimulates the ovaries and adrenal glands to produce even more hormones that affect development and maturity.
The increased amount of FSH and LH cause hyalinization and fibrosis, the growth of excess fibrous tissue, in the seminiferous tubules, where the sperm are normally located.
Hypogonadotropic hypogonadism (HH) occurs when the body does not produce enough of two important hormones, luteinizing hormone (LH) and follicle stimulating hormone (FSH).
Tests may be done that check estrogen levels (women) and testosterone levels (men) as well as FSH levels and LH levels, the pituitary hormones that stimulate the gonads.
