What causes low semen survival?

Many men have low sperm survival rates, and such men are likely to have symptoms of low fertility. Generally speaking, as long as the sperm survival rate in semen is less than 60%, it means that there is a low sperm survival rate. If you want to have a healthy child, you must first improve the quality of sperm. So what factors will affect the sperm survival rate?

Disease factors

(1) Sexual intercourse:

Sexual intercourse can reflexively cause the contraction of the vagina and uterus, accelerating the movement of sperm. Sex medicine research has confirmed that the vagina contracts rhythmically during female orgasm, and the uterus is also in a contracted state. Animal experiments have shown that repeated mating stimulation can greatly accelerate the movement of sperm and increase fertilization rates.

(2) Estrogen:

Estrogen can enhance the contraction of the fallopian tube. In the preovulation and ovulation period, when estrogen is dominant, the secretion of the fallopian tube increases, and the fallopian tube moves from the proximal end to the distal end in segments, pushing the sperm and fallopian tube fluid step by step from the uterus to the ovary. Sex hormones can also affect the movement of sperm by affecting the properties of the cervix and fluid.

(3) Prostaglandins:

There are many kinds of prostaglandins in semen and the female reproductive tract, which have a contraction effect on the non-pregnant uterus and fallopian tubes. In addition, estrogen can enhance this effect. The sensitivity of the uterus to prostaglandins is higher in the middle of the menstrual cycle.

(4) Cervical mucus:

Cervical mucus serves as a sperm storage area, protecting sperm from the adverse vaginal environment, providing energy for sperm, and may be involved in sperm capacitation.

(5) Impact on spermatogenesis. The reason why men have sperm is that it is controlled by a certain spermatogenesis system. If any part of the spermatogenesis system is abnormal, it will cause spermatogenesis dysfunction.

If the low sperm survival rate is not caused by disease factors, then you can improve your sperm condition by adjusting your diet. Eating more foods rich in protein selenium, protein zinc, etc. can effectively improve sperm survival rate. If this situation is caused by disease factors, then you need to go to the hospital in time to choose the appropriate treatment method.
