There are many reasons for causing men in daily life, including oligozoospermia. However, there are many reasons for oligozoospermia. Patient friends should go to learn about it. Next, let's listen to the detailed explanation of experts from Beijing Jianguo Hospital.
What causes oligozoospermia
1. When varicocele occurs, the local temperature of the testis increases, and vasoactive substances increase, thereby affecting the spermatogenic function of the testis. However, the degree of varicocele is not proportional to sperm quality.
2. Cryptorchidism is one of the important factors affecting semen quality. About 60% of patients with unilateral cryptorchidism are infertile, so if sperm density is low and cryptorchidism exists, early treatment is necessary.
3. Chronic infection of the accessory reproductive glands can affect various laboratory indicators in semen.
4. Studies on autoimmune reproductive immunology have found that male autoimmune diseases can affect fertility, while antisperm antibodies can affect sperm production and transportation.
5. Normal spermatogenesis in men with endocrine abnormalities depends on the normal functioning of the hypothalamus pituitary gonad axis. Any link disorder can affect spermatogenesis, and other diseases such as thyroid and adrenal diseases can also affect the function of the gonads leading to oligospermia.
6. Chromosome abnormalities Chromosome aberrations have a serious impact on sperm density, motility, and morphology.
7. Other conditions such as excessive scrotal temperature, radiation damage, chemical drugs, and drug effects can all cause oligospermia.
Symptoms of oligospermia:
Symptoms of oligospermia: 1. Based on medical history and physical examination, it can be preliminarily determined whether there is cryptorchidism (9%) and varicocele (24%).
Symptoms of oligospermia 2. According to its specific symptoms and laboratory results, the possibility of urinary and reproductive tract infections can be determined. Frequent urination, urgency, pain in urination, and burning sensation in the urethra are its symptoms. Pyuria and pyogenic sperm are special symptoms.
Symptoms of oligospermia 3. Physical examination can reveal purulent secretions outside the urethral orifice, with local tenderness. Laboratory examination: increased pus cells in urine; Urine culture was positive for bacteria; Prostate fluid examination showed white blood cells greater than 10/HP. An immune test determines the presence of autoimmune disease. Karyotype analysis can determine whether there are chromosome abnormalities. (Ma Xueyi, an expert from Beijing Jianguo Hospital)
