As we all know, if a couple wants to have children of their own, it must be based on the health of both men and women. The female provides the egg and the male provides the sperm, and the combination of the two forms the primordial embryo sac. Finally, women go through ten months of pregnancy and then give birth.
It can be said that sperm is indispensable for women to successfully become pregnant. However, an Israeli study showed that men’s sperm count has plummeted! So if this continues, will humans face a reproduction crisis? Let's take a look.
1. Israeli study: Global male sperm volume has plummeted
A large-scale study by an Israeli team found that global male sperm volume and sperm concentration have dropped by more than 50% in the past 50 years, and the decline is showing signs of accelerating. Frankly, human beings are facing a reproductive crisis. This research has been published in the scientific journal " Frontiers in Human Reproductive Medicine" (Human Reproduction Update).
The research team of Hagai Levine, an epidemiologist at the Hebrew University of Jerusalem in Israel, extracted hundreds of internationally published papers related to male semen quality from 1981 to 2019, covering semen samples of more than 57,000 men in 53 countries in North America, Europe, Oceania, South America, Asia, and Africa. In order to ensure the scientific nature of the results, the team specifically eliminated samples from men who went to medical institutions to check their sperm count due to fertility problems.
The results found that between 1973 and 2018, the sperm concentration of global men dropped by 51.6%, from 101.2 million sperm per milliliter of semen to 49 million, and the total sperm volume dropped by an average of 62.3% during the same period. Data show that the decline in human sperm volume is accelerating, with male sperm concentration falling by an average of 1.16% per year.
But if only the data after 2000 are calculated, the decline rate reaches 2.64%. However, research indicates that the reason for the sharp decline in human sperm count is currently unknown. Looking at the WHO standards, male semen contains 15 million to 200 million sperm per milliliter, which is within the normal range.
Hagai Levine said in an interview with the media that if the global average male sperm concentration is 50 million, it means that a large number of men have a sperm concentration below 40 million, which means that their fertility is suboptimal. At the same time, he warned that human reproduction is in crisis and all parties must respond immediately to avoid reaching an irreversible critical point.
2. Bad habits may affect male fertility
Perhaps the above research may indeed cause a human reproduction crisis, but according to World Health Organization statistics, 9% of couples around the world are troubled by fertility problems, of which male factors account for half. Some studies have pointed out that eating habits, obesity, stress, exercise habits, as well as excessive drinking, smoking, disease, use of recreational drugs (such as marijuana) and other bad lifestyle habits may be related to the decline in male fertility.
To put it simply, semen is composed of sperm and seminal plasma. Seminal plasma is the secretion of gonads, including the prostate, seminal vesicles , bulbourethral glands, paraurethral glands , epididymis, etc. Its main component is water and contains a small amount of nutrients to maintain the osmotic pressure balance, maintenance, stimulation, and protect the vitality of sperm in the semen.
3. 6 major nutrients to improve sperm activity
Generally speaking, if you want to get pregnant successfully, you must first learn how to keep sperm active. Men can help increase sperm activity by taking in the following 6 major nutrients:
Water: , as the main component of semen, has the function of lubricating and protecting sperm, but please note that if the drinking water is contaminated, it may affect male fertility.
Vitamin : Vitamins C, D, and E can promote sperm production and enhance sperm activity. It is recommended to get more sun to help naturally synthesize vitamin D, and eat more nut foods to supplement vitamin E.
High-quality protein : As a raw material needed for sperm survival, arginine is the main component of the sperm head, which helps improve sperm motility. It is recommended to eat more lean meat, eggs, fish and shrimp, etc.
Calcium and magnesium : As necessary substances to improve sperm protease activity and metabolism, it is recommended to eat more dark vegetables, soybeans, kelp, dried shrimps, etc.
Zinc and folic acid : Help increase the total number of sperm. It is recommended to eat more oysters, shellfish, clams, shrimps, animal livers, etc.
Selenium: is a component that makes up the sperm tail. If it is deficient, the sperm will be bent and its motility will be reduced. It is recommended to eat more red meat and seafood.
4. Three key points for nourishing sperm
In addition, we also remind everyone that in addition to taking in more of the above 6 nutrients, there are three key points that everyone must pay more attention to in order to effectively nourish sperm:
1. Life patterns
In real life, it is recommended that everyone must have a balanced diet, maintain a normal work and rest, and develop good living habits.
2. Avoid bad habits
Drinking alcohol and smoking can damage sperm production in several ways. Drinking alcohol, for example, may increase your liver's production of estrogen, which can lower your sperm count. In addition, alcohol will directly poison the sperm-producing cells of the testicles. Therefore, from this perspective, for male friends, if you are preparing for pregnancy, you must avoid smoking and drinking.
3. Pay attention to heat dissipation
Some people think that wearing tight pants will have a negative impact on fertility, so take off those loose cotton underwear! Additionally, testicles function best (including sperm production) at slightly below core body temperature, and regular use of hot tubs and saunas may lower sperm count because heat may reduce sperm production.
In short, nowadays, due to factors such as lifestyle, eating habits, social environment, etc., the quality of male semen, sperm quantity and motility are prone to continue to decline. Therefore, if you want to successfully conceive, in addition to women raising eggs, men also need to raise sperm. It takes about 90 days for a sperm to mature, and sperm is very sensitive to the environment inside and outside the body. Therefore, men are reminded to ensure that the sperm is in good condition before conception, so that pregnancy is more likely to be successful.
