Sperm are about 60 microns long in the vagina, while a woman’s vagina is 8 cm (80,000 microns) long. If it weren’t for ejaculation, just this distance of the vagina would be enough for tadpoles to trek. In addition, they have to break through the cervical mucus and other barriers, and if they are not in good health, they will buckle before they see the shadow of MM’s egg! The body is the capital of the ****, this is not bad at all ah! The actual fact is that you can find a lot of people who have been in the business for a long time. However, if you spill the seeds on the wall, the ground, their lives will be much shorter! Sperm exposed to the air will die of dehydration within minutes! Those who die from smoke, those who die from alcoholic beverages Everyone on earth knows that the reason why the balls hang outside the body is to maintain a lower temperature to ensure proper sperm production. Temporary poor heat dissipation can lead to a decrease in sperm quality over a period of time, while if you are sweltering for a long time, it can greatly affect the viability and quality of sperm. Radiation Shot If they are unfortunate enough to hit a condom, Mr. Sperm’s evil thoughts of hooking up with the egg MM are basically out of the window. They are left to spend the rest of their lives miserably in latex containers. The spermatozoa are swallowed by macrophages after vasectomy Syphilis spirochetes are small, slender, spiral-shaped microorganisms with pointed ends, which are transmitted mainly through sexual contact, placenta, birth canal, etc. A very small number of people are infected through non-sexual contact, blood transfusion, indirect contact, etc. Sperm infected with syphilis spirochetes have lower survival rate and motility than normal sperm, and are prone to malformation. Death by spermicide The epididymis is the reservoir of sperm. Sperm coming out of the testicles must be stored in the epididymis for a certain period of time before it has the ability to fertilize an egg. However, sperm stored for a long period of time will undergo degradation changes due to aging and inactivation, such as deformation of the acrosome and changes in DNA content and chromosomes.
