Friends who have ejaculated after sexual intercourse know why they have had sexual intercourse, and after the end, the female vagina will discharge semen, causing many people to worry about infertility. In fact, semen outflow after sexual intercourse is a normal phenomenon.
Semen includes sperm and seminal plasma, which is composed of secretions from the testis, seminal vesicles, prostate gland, urethral bulb gland, and paraglandular gland. After normal sexual activity, sperm immediately leave the semen pool in the posterior dome and enter the cervical canal. The semen left in the vagina overflows after completing its mission, or is decomposed by enzymes in the vagina. Therefore, semen overflow after sexual intercourse is a normal phenomenon.
The fluid produced by the female reproductive tract during seminal plasma outflow abnormalities, inactive sperm, and sexual arousal. However, in order to ensure that as many sperm enter the cervix as possible, it is possible to raise the buttocks after sexual intercourse to avoid premature semen overflow from the vagina, which can affect the chances of conception. After male ejaculation, semen is stored on the dome behind the female vagina. The cervix and the mucus it secretes act as a barrier, and healthy and energetic sperm in the semen quickly move towards the cervix through the swing of the tail. Uterine contraction and peristalsis of the fallopian tubes pass through the cervical mucus, pass through the uterine cavity, and finally reach the fertilized site. The ampulla of the fallopian tubes is deformed and has low mobility, Dead sperm and other components in semen cannot enter the uterine cavity through the cervix.
If prostate fluid enters the uterine cavity, the contained prostate will stimulate uterine contraction and cause abdominal pain. What role does seminal plasma play? Sperm is a transportation vehicle transported from the male reproductive tract to the female reproductive tract, and is also a buffer substance. Alkaline seminal plasma neutralizes the acidity of vaginal fluid, protecting sperm from damage. seminal plasma provides nutrition and energy for sperm, maintains a certain osmotic pressure, and is conducive to sperm survival.
