New Zealand researchers found that men taking antioxidants such as vitamin E and zinc may enhance fertility. Point of view Researchers at the University of Auckland in New Zealand have targeted research subjects for men with low fertility, ie, below fertility but still fertile. Reuters reported on January 20th that statistical results showed that one out of every 20 men suffers from low fertility problems, and half of the couples' late childbearing is due to low male fertility. Medical experts believe that 80% of male fertility is low because sperm is oxidized, the quantity is reduced, and the quality is reduced. Sperm oxidation is triggered by a molecule called free radicals. Free radicals are metabolites of cells and have strong oxidative properties that can damage body tissues and cell functions. Antioxidants contain certain vitamins and nutrients that help cells defend against free radical damage. Some scholars have speculated that taking anti-oxidants in men may help sperm keep swimming. The researchers reviewed previous reproductive studies and hoped to obtain data to support this view. Retrospective studies The researchers reviewed 34 fertility treatment studies involving nearly 3,000 couples. Treatments include in vitro fertilization and intrauterine artificial insemination, the two most commonly used methods for infertility caused by low sperm quality in men. Analysis of 96 cases of successful pregnancy in the 15 studies revealed that men's fertility increased more than four-fold after taking anti-oxidants, and the probability of a spouse delivering live births increased five-fold. Marianne Chavwell, research director, said: "Oral antioxidants may increase the chances of couples getting pregnant to some extent." The research report was published by The Cochrane Library, an online medical e-magazine. However, researchers believe that the idea that antioxidants enhance male fertility is not absolutely correct, and more research results need to be confirmed. Questioned The study was questioned by some fertility experts. Lawrence Rose, professor of urology at the University of Illinois, said: "There are obstacles in male sperm function. It is not appropriate to use antioxidants to treat the disease without identifying the cause." Other experts questioned the research methods and the number of research subjects. Of the 34 studies reviewed by the researchers, none involved more than 1,000 participants, and some studies only involved 10 participants. Mark Sigman, a professor at Brown University in the United States, said: "Research shows that antioxidants can increase the likelihood of babies being born safely. This conclusion is based on only 20 cases and the number of samples is relatively small." He believes that the study involves resistance Different types and amounts of oxidants cannot determine the effectiveness of each antioxidant. "The idea that a treatment is effective for most couples is unrealistic," said Sigman. "While there is no evidence that antioxidants are harmful to human health, we do not know which antioxidant or doses will enhance fertility. Antioxidants have been approved by the Food and Drug Administration of the United States for the treatment of infertility, and consumers should not listen to biased beliefs."
