In real life, there is no girl who looks for a partner without looking at her face, in fact, in the process of childbirth, the beautiful Miss Egg is also selecting sperm, and handsome sperm has a better chance of being selected.
Some experts pointed out that the incidence of infertility in couples of childbearing age in industrialized countries has been on the rise since the 20th century.
In order to save fertility, many patients have also taken a lot of medical measures, but the benefits may not be significant, and the latest research provides us with new ideas for improving male fertility.
01PLoS Biol: Human sperm respond quickly to dietary interventions
In a new study published in PLOS Biology, researchers from Linköping University in Sweden have found that sperm are affected by diet, and that this effect can occur quickly.
In the study, researchers studied 15 healthy and non-smoking young men between the ages of 20 and 27 and individualized dietary management.
Participants followed a two-week diet provided by the researchers.
Week 1: Healthy eating based on Nordic nutritional advice. Week 2: The researchers added an average of 375 grams of sugar per day to their diet, which is equivalent to 3.5 liters of sugar-sweetened beverages or 450 grams of candy.
Semen samples were collected three times, at the start of the study, after the first healthy eating week, and after the second high-sugar diet. At the same time, the researchers also recorded other health indicators of the participants.
The researchers noted.
It is worth noting that
By plotting this low sperm motility group alone, the researchers can clearly observe,
But we can't say for sure that sugar is responsible for this effect, as it may be an integral part of a basic healthy diet.
Doesn't this literature tell us that eating a healthy diet in as little as one week can have a positive effect on sperm than any medication or other lifestyle intervention?
So
02 What to eat to make sperm look more handsome?
(1) Crude carbohydrates
Due to the different processing methods of raw materials, carbohydrates can be divided into crude and refined, like
These foods are also more conducive to men to maintain weight, improve glucose and lipid metabolism, and reduce inflammation.
A healthy weight, normal blood sugar metabolism, is the basic guarantee of sperm quality, here we have talked a lot in the previous article, here will not be too much to repeat.
(2) High-quality protein
, which is the basis of conception.
If you want to improve sperm quality, you need to consume high-quality protein, and the types of high-quality protein foods that can be obtained in life are:
Meat is both one of the largest sources of animal protein and the most likely food to affect male reproductive health.
The study found that
Care needs to be taken here to minimize the intake of red meat,
Red meat is high in saturated fat and cholesterol, which may affect sperm quantity and quality. Therefore, in the diet, we should consume red meat in moderation.
Since the vast majority of milk is produced by pregnant or postpartum cows, milk contains a lot of estrogen, which is not good for sperm quality, is this really the case?
A study in Human and Reproduction included men aged 18-22 who studied the relationship between dairy products and male semen quality.
(3) Healthy fats
Fat also contains essential fatty acids required for sperm production, and a proper fat ratio is essential for sperm quality.
The imbalance between omega-6 and omega-3 fatty acids in sperm is associated with lipid peroxidation and DNA damage in spermatozoa, suggesting a possible association with fertility potential.
In a study in the Journal of Reproductive Medicine, it was found that men with high DNA fragmentation showed higher percentages of total saturation, monounsaturation, and omega-6 to omega-3 fatty acid ratios in sperm and seminal plasma compared to men with low sperm DNA fragmentation rates.
This suggests that
(4) Stick to nuts
The reason why it's taken out separately is because it's really too important for men,
The researchers recruited 72 healthy and non-smoking men aged 18~35 years and divided them into two groups: nut group and control group.
People in the nut group, added to a normal Western-style diet. People in the control group followed only a normal Western-style diet and avoided nuts.
The results of the study showed that the addition of nuts to a regular Western diet may lead to changes in sperm epigenetics, which in turn affects sperm quality and its ability to fertilize.
In addition, a previous study published in the journal Nutrition showed that
From the analysis of nutrient content,
(5) Reasonable supplementation of trace elements
Don't think of trace elements as nutritional supplements, many studies have shown that
Years of scientific research have confirmed that sperm are more likely to have a normal chromosome count and better semen parameters if a man's diet contains more antioxidants.
For example, the researchers found that
Without knowing which antioxidant is the most effective,
In the book "Good Pregnancy, Starts with the Egg", I found an interesting study that found that men experienced surprising changes after switching to fruits and vegetables with fewer pesticide residues.
In short, instead of worrying about how to improve sperm quality through medical means such as injections and medicines, it is better to eat a real diet.
In fact, by consulting the literature, I also changed my own cognition.
So, what are you waiting for, let's hurry up and get pregnant while enjoying the food!
