Urban men have become one of the most important and worst diseases that trouble them.There are many reasons for male infertility, and genetic factors are also one of the most influences.Male infertility experts will introduce you to several main genetic factors that cause male infertility in this article.
1. Clean Felt's syndrome (KLINEFELTER, congenital testicular dysplasia)
This disease is more common, accounting for about 1/500 among male newborns, and was first described by Drklinefelter in 1942, so it was 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. Turner syndrome
Most of the patient's chromosomal nucleus is still 46 and xy; only a few are chromosomal 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. Sexual reversal syndrome
The clinical manifestations of this disease are similar to the Clean Felt's syndrome. The appearance is male and has a male psychological state, but the testicles are small, and there is no pubic hair or pubic hair.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 movement abnormalities.The reason is that the cilia of these parts occurs.
5. Only support cell syndrome
The incidence 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.
Men's infertility caused by genetic factors is often difficult to treat. It is necessary to consult a physician to treat the disease as soon as possible to avoid missing the best opportunity for fertility.
