According to a study published in the journal Human Reproduction Update, of the University of Oxford, in the Uk, the quality of sperm from men in north America, Europe and Australia has halved in the past 40 years.
The research epidemiologist Hagai Levine of the Hebrew University of Jerusalem, he assembled the results of 185 studies between 1973 and 2001, the analyzed semen samples from nearly 43,000 men, making it one of the investigations largest of its kind.
This study found a decrease of 52.4% in the concentration of sperm and a decrease in the sperm count of 59.3% in men from north America, Europe, Australia and New Zealand. In addition, this decrease is continuous and possibly is on the rise.
Causes of this decline
There is No clear evidence to explain the apparent decrease in the number of spermatozoa in the last 40 years. However, a decrease in the quality and sperm count has been associated with exposure to chemicals and metals in the food, those used in plastics and pesticides, obesity, smoking, stress, a diet high in saturated fat and a sedentary lifestyle.
What determines the health of the sperm?
The health of the sperm depends on a number of factors such as:
Amount: the ejaculate should contain between 15 and 200 million sperm per milliliter to be considered fertile. You have less, you might have difficulty conceiving.
Movement: The sperm must swim through the cervix, uterus and fallopian Tubes of a woman to achieve to reach the egg and fertilize the egg. This is known as motility and must have at least 40% of the motile sperm to have a higher chance of achieving a pregnancy.
Morphology: a sperm has normal oval-shaped head and a long tail that move together to produce thrust. This is not a factor just as important as the quantity and motility, but the more sperm with shape and structure in normal you have, the more chances of achieving a pregnancy.
