What are the causes of blood in the urine after sexual intercourse in men?

Many male friends will experience hematuria after sexual intercourse. Due to the lack of knowledge about men's diseases, they do not know what disease hematuria after sexual intercourse is, and thus delay treatment, which ultimately causes unnecessary harm to their physical and mental health. So what are the causes of hematuria in men after sexual intercourse?

【Hematuria after sexual intercourse caused by urinary tract infection】

Because men suffer from urinary and reproductive infections such as balanitis, urethritis, cystitis, and seminal vesiculitis, if not treated in time, the inflammation will cause unnecessary harm to the male reproductive organs, which will also induce a series of adverse symptoms, such as abnormal urination, difficulty urinating, hematuria and other adverse symptoms. During sexual intercourse, men will bleed due to the stimulation of inflammation when their penis is fully erect, resulting in hematuria when men urinate after sexual intercourse.

[Hematuria after sexual intercourse caused by prostatic hyperplasia]

Hematuria is a typical symptom of prostate hyperplasia, mainly because the enlarged prostate will compress the bladder, resulting in abnormal excretion. Long-term retention of urine in the body will cause bacteria in the urine to induce infection, and irritation to the bladder mucosa will cause bleeding. The capillaries in the mucosa on the surface of the prostate will become congested, dilated and twisted. When the bladder contracts or the enlarged prostate is pulled, the capillaries will rupture and bleed, which will be discharged along with the urine, forming hematuria.
