1. The incubation period of mycoplasma infection is 1-3 weeks. Typical acute symptoms are similar to other nongonococcal reproductive and urinary system infections, which are manifested as urethral tingling, urgency, frequent urination and dysuria, especially when urine is concentrated. The urethral orifice is slightly red and swollen, and the secretion is thin and less, which is serous or purulent. You need to squeeze the urethra hard to see the secretion overflow. Often there is a small amount of mucus secretion at the urethral orifice or only the scab membrane is closed, or the crotch is unclean.

2. In the subacute stage, prostate infection often occurs. When patients are undergoing levator ani surgery, they often have perineal swelling pain, back pain, discomfort on both sides of the inner thighs or tingling pain diverging from the perineum to the inner thighs.

3. Female patients are more likely to see genital inflammation spreading around the cervix. Most of them have no obvious symptoms, and a few severe patients have a feeling of vaginal distension. When infection spreads to urethra, frequent urination and urgency are the main symptoms that attract patients' attention. The infection is confined to the cervix, showing increased leucorrhea, turbidity, cervical edema, congestion or surface. The infection spread to the urethra, characterized by flushing, congestion and squeezing of the urethra, with a small amount of secretions overflowing, but little tenderness.

4. The common complication of mycoplasma infection is salpingitis, and a few patients may have endometritis and pelvic inflammatory disease.

The hazards of mycoplasma infection are as follows:

First, the increase of sperm deformity rate: the increase of sperm deformity rate caused by mycoplasma infection is another feature of infertility. According to clinical observation, in this kind of infertility patients, the abnormal rate of sperm can sometimes be as high as 80%.

Second, the fallopian tube is not smooth: upward infection can cause endometritis, pelvic inflammatory disease and salpingitis, especially salpingitis. It can cause incomplete obstruction of tubal inflammatory adhesion, make the lumen narrow and unobstructed, and cause ectopic pregnancy or female infertility.

Third, destroy spermatogenic cells: there are a large number of spermatogenic cells in the seminiferous tubules of testis, which develop and reproduce to form sperm. When mycoplasma enters testicular seminiferous tubules from urethra, prostate and other parts, it will destroy spermatogenic cells, make spermatogenic factories produce fake and inferior products, and lead to infertility.

Perinatal hazards: Mycoplasma infection can spread upward through placenta or lower reproductive tract infection, causing intrauterine infection leading to abortion, premature delivery, intrauterine growth retardation, premature rupture of membranes and even stillbirth.

Fifth, it is easy to cause abortion due to Ureaplasma urealyticum infection. The possibility of mycoplasma infection should be considered for those who have multiple abortions for unknown reasons.
