What is the sperm capacitation time?

Many people do not know when they are doing sperm capacitation. Generally, sperm capacitation takes time to combine, so that the capacitation effect will be better. Sperm capacitation allows men to have better fertility, which is a good thing for men. If something abnormal happens during sperm capacitation, it will lead to failure of capacitation and even affect fertility. So how long is the sperm capacitation time?

It takes several hours. The fertilized egg will implant in the uterus within 7 days. It is recommended to drink plenty of water, eat balanced nutrition and eat more fresh fruits and vegetables. Increase nutrition and supplement vitamins and trace elements. Supplement protein

Under physiological conditions, sperm must first pass through the female reproductive tract and stay for a period of time before they can acquire the ability to fertilize the egg, which is called sperm capacitation.

The essence of capacitation lies in exposing the egg recognition factors and binding factors on the surface of the sperm membrane, releasing the inhibition of the sperm apicosome reaction, and enabling the sperm to recognize the egg and penetrate into the egg to complete fertilization.

Capable sperm undergo a series of specific changes in structure and function, including: sperm superactivation; changes in sperm metabolism; changes in sperm membrane; and changes in sperm morphology.

Sperm Super Activation

Movement pattern: Powerful, asymmetric movement with a "whip-like" tail (sperm hyperactivation).

Indicators for determining sperm hyperactivation: increased trajectory speed, decreased linearity, decreased forward motion, and increased lateral swing. Using CASA, the criteria are different.

Physiological significance: 1. It is beneficial for sperm to pass through the viscous medium in the fallopian tube cavity; 2. It provides a mechanical basis for sperm to penetrate the corona radiata and zona pellucida.

Metabolic changes

Capable sperm use glucose as their main energy source and function in both aerobic and anaerobic modes.

Changes occur in the enzyme and signaling systems of capacitated sperm: ① adenylate cyclase is activated; ② phospholipase is activated; ③ protein phosphorylation is intensified.

It takes about several hours for sperm to become capacitated, but this varies from person to person. Don't be anxious during the sperm capacitation process. If you are too anxious, it will be very disadvantageous to yourself. You must be patient during the sperm capacitation process and pay attention to the movement method. You must do sperm testing at any time to find out whether there are any abnormalities in your sperm. If any abnormalities occur, you must receive timely treatment.
