Sperm reproduction is the process of complete birth and maturation of sperm. This process aims to provide a continuous and abundant supply of sperm for the most important purpose of fertilizing a woman's egg to create a pregnancy. So how does sperm regeneration work and how much is it? How to keep sperm healthy? All will be answered in this article.
1. How long does it take to regenerate sperm?
Sperm are produced daily in a man's body, but a full cycle of spermatogenesis takes about 64 days.
During sperm production, also known as spermatogenesis, each testicl* will produce about a few million sperm per day, meaning that every second that passes, 1500 sperm are born. At the end of a full sperm production cycle, a man's body can regenerate up to 8 billion sperm.
This number may sound like an overkill, but every milliliter of sem*n released during ejacul*tion contains 20-300 million sperm cells. Therefore, it is necessary to regenerate sperm in such a large amount, to ensure that the sperm supply is always new and abundant, best serving for conception.
2. How does the sperm regeneration cycle work?
The spermatogenesis cycle goes through the following stages:
Division of diploid sperm cells into haploid cells that carry genetic data. Sperm maturation in the testicl*s, especially in the vas deferens: Hormones help pre-sperm cells go through this process until they become sperm. The sperm then remains in the testicl* until it is almost fully mature. Mature sperm have a genetic head and a tail that helps them swim through the cervix to fertilize an egg. Movement of sperm into the epididymis: The epididymis helps to preserve sperm until ejacul*tion. This is also where sperm gain mobility, allowing them to travel long distances when released in sem*n.
3. Why is it important to understand sperm regeneration?
Sperm regeneration will continuously fill the epididymis with new sperm. The longer a man does not ejacul*te, the more sperm will accumulate, thus the higher the sperm count in one ejacul*tion.
Based on this, if a man and his partner are trying to get pregnant, they should ejacul*te every few days to increase the chances of conception. Besides, the chances of getting pregnant will increase if a man abstains from ejacul*ting in the week before his partner ovulates. This will maximize the chances of pregnancy when two factors are combined: the man's high sperm count and the woman's most fertile time (conception window).
On the other hand, frequent ejacul*tion can reduce the sperm count in each session. This can help reduce a woman's chances of getting pregnant, especially if men abstain from sex until ovulation ends.
4. What is healthy sperm?
The healthier the sperm, the higher the chances of conception occurring. In addition to sperm count, sperm health is also assessed by:
Sperm motility (motility) Sperm need to travel through a woman's cervix, uterus and fallopian tubes before reaching the ovaries. eggs for fertilization. Sperm motility is measured by the number of motile sperm. A man is considered fertile when he has at least 40% motile sperm.
Sperm shape (morphology) Normal sperm have a long tail and an oval head. A higher number of normal-shaped sperm means a higher conception rate.
5. How to improve sperm health?
To ensure that sperm is produced in large enough quantities, with high mobility and uniform shape, you can try the following:
Regular exercise A 2014 study analyzed 433 sem*n samples from 231 participants showed that men who were active outdoors or lifted weights for 3.2 hours a week had up to 42% higher sperm counts than inactive men. exercise.
Get enough vitamins C and D with meals A 2016 study of 200 men found that those who lost weight and took 1000mg of vitamin C per day had an increase in the number and mobility of the body. sperm.
Another 2015 study of 102 couples also showed that men with normal levels of vitamin D in their blood samples had a higher pregnancy rate than their male partners with vitamin D deficiency. D, although there was no difference in sperm count and motility.
Get enough lycopene Some studies suggest that consuming 4-8 mg of lycopene per day can help increase sperm count and viability, or the number of sperm in a given sem*n sample. Lycopene is an antioxidant found in many red fruits and vegetables such as tomatoes, papaya, guava, peach, grapefruit,...
Limit or quit smoking A review drawn From a total of 33 studies dating back to 1982, smoking had a marked negative effect on sem*n quality and sperm function, especially in fertile men. .
Limit alcohol intake Research carried out on 1221 men shows that the more alcohol a person drinks, the more likely they are to produce abnormally shaped sperm. Additionally, a link exists between alcohol consumption and low testosterone levels, which affects reproductive function.
Wear underwear and loose clothing The testicl*s need to be suspended to maintain a temperature of 35-37 degrees Celsius, which is cooler than body temperature. These are the optimal environmental conditions for sperm production. Wearing tight underwear, jeans or other tight clothing will squeeze the testicl*s into the body and increase their temperature, causing sperm to lose motility and viability.
6. How to increase the chances of conception?
Have sex 2-3 times a week: Increases your chances of producing healthy sperm in the largest volume of sem*n possible. To do that, men need to abstain from masturbation in between sex Use an Ovulation Predictor Kit: This tool helps test the levels of luteinizing hormone (LH) in a person's urine. women. LH levels will increase just before ovulation. If the test is positive, have sex on the day of the test. Having sex in the next few days also increases your chances of conception. Do not use oil-based lubricants: These can negatively affect sperm health See your doctor for a sem*n analysis if you have been trying to conceive for more than 6 months without success: Sperm health depends on many factors such as age, diet and overall sperm count. The doctor will base on the results of the sem*n analysis to determine the male's sperm health and assess the possibility of conception, as well as advise on how to solve it. Thus, the man's body produces new sperm every day. days and the complete spermatogenesis cycle is 64 days. This is to ensure that men always have an abundant source of sperm for conception.
The quality and quantity of sperm is greatly influenced by diet and lifestyle. Therefore, men need to eat and exercise scientifically, avoid unhealthy behaviors (alcohol, smoking, ...) to keep sperm as healthy as possible.
