Common genetic diseases that can cause male infertility are:
(1) The Clean Felter syndrome (KLINEFELTER, congenital testicular dysplasia) This disease is more common, accounting for about 1/500 among male newborns.The first year is described, so this is named.This disease is usually asymptomatic in childhood, and symptoms occur during adolescence. The typical clinical manifestations are: the limbs grow too long, the muscle development is poor, common female breasts, the facial and body hair is sparse, the testosteria is small and hard.Fiberization and glass -like degeneration, severe disorders or stopping in the process of raw essence, high FSH and LH in the blood, low -sex gonad function, mostly accompanied by dull intelligence.This is caused by abnormal sex chromosomes and cannot be cured.
(2) The chromosome nucleus of Patients in Turner syndrome are still 46 and XY; only a few are chromosomal chromosomes.The clinical manifestation is short body, low neck, low ears, shield chest, urgent test disorders, low levels ofrogens in serum, and most of them lose their fertility.
(3) The clinical manifestation of the sexual reversal syndrome is similar to that of the Klein Felt syndrome. The appearance is male, with a male psychological state, but the testicles are small, and there is no pubic hair or a pussy.The chromosome nucleus is 46, xy.
(4) Cillar stagnation syndrome This disease is mostly a family history of close relatives. The clinical manifestations are internal organs (such as: right heart), bronchial expansion and chronic sinusitis, and sperm tail cilia exercise abnormalities.The reason is that the cilia of these parts occurs.
(5) Only supporting the incidence of cell syndrome of this disease is about 3%.There is no congenital abnormal manifestation in the shape, but there is no sperm cells in the testicles, no sperm, and serum FSH elevated, but testosterone levels are normal.
