2. Hidden dangers of occult blood

1. It can cause infection. When one spouse is sick, the possibility of the other being infected is as high as 70%. Family members who come into contact with the bedding, towels, and bathtubs used by the patient have a 40% chance of indirect infection.

2: It causes multiple inflammations. Although the local symptoms of reproductive infection can be alleviated or disappear within a certain time and range, it does not mean that the disease has been cured. It is very likely that the disease will turn from acute to chronic, and the lesions will spread to a deeper level. If a man experiences pain during penile erection, swelling and discomfort in the perineum and anus at night, this indicates that nearby organs such as the prostate, testicles, and epididymis have been affected.

3. It can cause male infertility. According to clinical statistics, about 15% of married couples are infertile, and nearly 50% of the reasons are from the male side. Reproductive infections have become the main cause. It can affect the quality of male sperm, causing oligospermia and sperm deformity, directly leading to a decrease in male fertility.
