Men’s semen quality may be associated with changes in the seasons
The semen of men suffering from infertility was analyzed over 32 months. Researchers found that sperm head abnormalities were common in the fall but not in spring. This is because, during the hot summer months, scrotal temperature is high. So come the fall, semen with such sperm head deformities is released. Increased sperm head defects may be associated with elevated scrotal temperature.
In summer, the proportion of immature sperm is higher than in other seasons, due to the heat. In winter however, sperm tail defects are common, so spring shows the highest frequency of sperm tail defects. Such sperm has poor motility, making egg fertilization difficult. Overall, the highest sperm counts were found in winter, followed by spring; sperm activity is strongest in autumn and winter.
More sun makes healthier sperm
Australian experts examined the blood of nearly 800 men suffering from infertility problems, and found that levels of vitamin D were below normal in nearly a third of them. Vitamin D plays an important role in improving the quality of sperm, and the sun is the main source of vitamin D. Vitamin D deficiency is prevalent among men who cannot make their partner pregnant.
Researchers analyzed an important factor in male fertility ─ sperm DNA fragmentation, and the results were astonishing. It was obvious that infertility is associated with cytotoxicity ─ amino acid homocysteine levels in the blood increase, while new healthy cells lack important folic acid. Men who made lifestyle changes and took vitamin D supplements saw their infertility problems significantly improve. We know that vitamin D and folic acid deficiencies are related to women’s infertility but the results of this research carried out on men is surprising.
In another study that tested 794 men, 58% had a higher frequency of DNA breaks. 100 men agreed to quit smoking, minimize caffeine and alcohol intake or completely avoid these two substances, lose weight, and increase their levels of vitamins and antioxidants within three months before the start of fertility treatment. The results showed that the majority of sperm quality significantly improved, 40% of men achieved clinical pregnancy, and 11% conceived naturally.
To nurture a healthy baby starts from the culture of quality sperm. These are some factors that affect sperm quality:
1. Smoking and alcohol
2. High testicular temperature
4. Too frequent sexual intercourse
6. Sexually transmitted diseases
