Researcher Germaine Buck Louis said that about 15% of couples in the United States do not successfully conceive during the first year of trying to conceive, and male infertility plays an important role in this. Our goal is to explain the relationship between the impact of environmental factors and the quality and health of male sperm. Sperm quality is an important indicator of male fertility, and it is often judged by the number, shape, athletic ability, and other factors of sperm.
In the article, researchers tracked more than 500 couples from Texas and Michigan over the past year, who were emotionally loyal to each other and stopped contraception; All male participants in the study completed preliminary tests, in which they were asked about their reproductive history, health status, lifestyle, and professional activities. Most men provided a sperm sample for the study.
The final study included 456 men with an average age of 31.8 years, of whom 77% were white, 91% had a college education, and more than half had no children; Researchers have found that 13% of men who engage in physical work have fewer sperm counts than men who do not engage in physical work (6%); In contrast, no other work pressures, such as heat, noise, and prolonged sitting, can also affect sperm quality in men.
When studying male individuals diagnosed with hypertension, diabetes or high cholesterol, the researchers found that the proportion of normal shaped sperm in hypertensive individuals was less than that in non hypertensive individuals; Dr. Michael L. Eisenberg said that as men have to bear and raise children in later life, health issues that we once thought were completely unrelated to fertility may need to be reconsidered. Future research will need to analyze whether hypertension itself or therapy affects men's fertility.
Finally, the researchers also found that men who take a large amount of drugs may have a higher risk of having a lower sperm count in the body. For example, in 7% of men who do not take drugs, the individual sperm count is below 39 million, with a normal range of 40 million to 300 million, while in 15% of men who take one or more drugs, the individual sperm count is below 39 million. Finally, the researcher said that if the above factors are confirmed to have a negative impact on male infertility, individuals may be able to eliminate the negative factors affecting male fertility through certain changes in daily life, such as treatment or changing work methods.
