according to the daily mail of the UK, British scientists have formulated a formula for defining "perfect sperm", which is infertile. The couple is a great gospel. Although it seems complex and confusing, this equation describes the speed of sperm moving toward the egg, taking into account the length of the sperm tail and the speed of the swinging.
is just one of the series of equations that scientists hope to use to find the most dynamic sperm to help couples who are undergoing fertility treatment.
University of Birmingham's research team even thinks they can create a mobile phone application that can evaluate a man's fertility in a few seconds by analyzing a magnified image of a sperm sample. "This is expected to change fertility therapy," said Dave />
currently, the proportion of couples facing fertility difficulties is 1/6, and sperm defects are considered one of the reasons why half of the couples are unable to give birth. However, the method of judging male sperm quality is not accurate at present, which leads to uncertainty in treatment.
professor Alan Allan pacey, male fertility specialist at University of Sheffield, said: "it is difficult to determine sperm quality. At present, the principles of relevant testing can be traced back to 1952.
experts now use a microscope to count the number of sperm moving in semen samples. They also observe sperm shape, but their judgments are subjective.
for men with very poor sperm quality, it is even more challenging to determine the best sperm injected into female eggs. This situation reduces the chances of a successful pregnancy.
