Is your biological clock ticking?  How about your husband’s?  That’s right, according to Researcher Paula Fettback, of the Huntington Medicina Reproductiva clinic in Brazil, men have their own biological clock.  Once in their 40s, men have a harder time fathering a child—with the odds decreasing every year, and rapidly decreasing after age 45.  Although men are constantly creating new sperm, this process can slow down with time.  Also, genetic errors may be more likely to appear in sperm of older men.  Although these new studies are certainly interesting, some experts caution not to put too much emphasis on their findings. Dr Richard Sherbahn, of the Advanced Fertility Center of Chicago, says that “any difference is likely to be just a few percent over decades,” and reminds readers that IVF can help “compensate for many problems with sperm, in a way that it can’t with eggs.”
