Methotrexate is usually given orally once a week, although it may also be given by injection. The dosage is generally 5 to 15 milligrams per week. Methotrexate is well tolerated by most patients. It does not predispose a patient to develop malignancies. However, liver disease and lung reactions can occasionally occur with the use of methotrexate and it can be sun sensitizing. Dosage may need to be decreased if kidney disease is present. Blood counts should also be taken each month in patients receiving this drug and dosage modified if side effects are detected.

Levels of prostate-specific antigen (PSA) should be checked at 3, 6, and 12 months. If the patient is truly hypogonadal to begin with, expect a significant rise at the 3-month assessment. Thereafter, the usual criteria apply regarding the possible presence of an underlying malignancy (>4 ng/mL, or rate of increase > ng/mL/2 yr or >2 ng/mL overall). These criteria continue to be revised by our urology colleagues, tending to become more stringent with time. For example, a PSA rise of more than 1 ng/mL/year has been suggested as an early warning guide, and closer surveillance has been recommended, even at rates of to  ng/mL/year. 2 A digital rectal examination should be performed at 3 to 6 months and at 1 year after therapy is initiated. A urologic consultation should be obtained if indicated.

Seminara et al. (2003) studied 63 unrelated patients with normosmic idiopathic hypogonadotropic hypogonadism and 20 patients with anosmic hypogonadotropic hypogonadism. In 1 patient, a black man with idiopathic hypogonadotropic hypogonadism (HH8; 614837 ), they identified compound heterozygosity for a 991C-T transition in exon 5 of the GPR54 gene, causing replacement of an arginine at residue 331 with a premature stop codon (R331X), and a 1195T-A transversion in exon 5, which replaced the stop codon at residue 399 with an arginine (X399R; ). This nonstop mutation resulted in the continuation of the open reading frame to the poly(A) signal, with no intervening stop codon.

Female ovaries are two almond shaped glands on each side of the uterus. They have three main functions; (i) Containing immature ova (eggs), (ii) The secretion of oestrogen, and (ii) the secretion of progesterone. Ostrogen is secreted by the adrenal cortex as well as the ovaries, and is present in the blood of all females from puberty through to the menopause. oestrogen acts on the structure of the reproductive organs, especially during the menstrual cycle. This induces and maintains female secondary sexual characteristics. Progesterone works on the uterus to prepare it for the implantation of a fertilised ovum (egg). It causes the development of the breasts, and is essential for the complete development of the maternal proportion of the placenta.
