In recent years, foreign scientists found that some male infertility patients, taking antibiotics, accidentally restored normal fertility. After further research, initially revealed the mystery, the original men’s infertility is one of the important causes of infection, about 40% of which is infected with mycoplasma caused. Mycoplasma is between bacteria and viruses, can live independently of the microorganisms, it can be inanimate artificial media growth and reproduction, the formation of small colonies. Mycoplasma has been shown to be pathogenic to humans in the form of Mycoplasma pneumoniae, Mycoplasma hominis and Mycoplasma solani. Among them, Mycoplasma solani is mainly parasitized in the human genitourinary tract, resulting in the following diseases: 1, sexually transmitted diseases: foreign research data show that mycoplasma infection of the genitourinary tract is a new independent sexually transmitted diseases, accounting for a large proportion of nongonococcal urethritis, second only to chlamydia infection and accounted for the second place, and is on the rise. Domestic survey in Beijing, Nanjing, Anhui and other places show that there is mycoplasma venereal disease in China, in the male non-gonococcal urethritis, its positive rate of 30%-60%, in the cervical secretions of female sexually promiscuous people, its positive rate of 50%-80%. 2.Inflammation of female reproductive tract: Mycoplasma can lead to vaginitis, pelvic inflammatory disease, adnexitis and so on. In the secretions of patients with cervicitis, its positive rate is 40%-80%. 3, intrauterine infection: the parasitic female lower genital tract of Mycoplasma hyopneumoniae upstream to the endometrium, leading to infection invasion of the amniotic sac, infection of the fetus, causing endometritis, chorionic villous amnionitis or preterm labor, stillbirth, low birth weight and perinatal diseases. Separation of Mycoplasma lupus urealyticum from the placenta or amniotic fluid often indicates that the pregnant woman is suffering from chorioamnionitis, umbilical cord infection and perinatal diseases, which often leads to shortened gestation period, fetal growth arrest and low birth weight babies. 4, neonatal infection: Mycoplasma urealyticum infects newborns in the birth canal and can cause congenital pneumonia and neonatal meningitis. 5, male infertility: from some infertile men’s semen, can be separated from the Mycoplasma hyopneumoniae, through the electron microscope examination found that the semen of the infected person, the spermatozoa are countless spherical mycoplasma and fibers of the rough intertwined material covered, sperm tail is coiled around the knot together, so as to make the speed and ability of its activities greatly reduced. It has been observed that mycoplasma can affect the forward swimming ability of the spermatozoa by invading their tails. Due to the significant reduction in sperm activity, making it difficult for sperm to pass through the vagina, cervical celiac disease, fallopian tubes and other layers of the tube card barrier, and can not meet and combine with the egg in time, resulting in infertility. In addition, the female reproductive tract carries Mycoplasma lupus urealyticum, may also have an impact on sperm penetration ability. Beijing, Nanjing, Anhui and other places of investigation, infertile couples semen and cervical secretion of mycoplasma detection rate of up to 60% -80%. 6, urinary tract stones: Mycoplasma urealyticum has urease enzyme, which can decompose urea and induce phosphate stones. Surgical removal of stones, 30% can be separated from Mycoplasma urealyticum. Animal studies have shown that injection of Mycoplasma urealyticum into the urinary system can cause stones in the corresponding areas. Infertility caused by Mycoplasma lysureum infection, after taking antimicrobials, can effectively kill the mycoplasma, thus improving sperm motility and significantly increasing the pregnancy rate within one year.
