This is one of a series of news items from abstracts of studies presented at the Annual Meeting of the American Society for Reproductive Medicine as complied by Dr. David Meldrum, Scientific Director of Reproductive Partners. We appreciate the enormous amount of work it takes to compile and comment on these abstracts.
Until recently there has been little evidence that the age of the male partner had a role in IVF success. Now in cases of egg donation where egg quality from young donors should be consistently good, the malke partner's has been identified as a factor in unsuccessful cycles.
Failure to conceive with oocyte donation was associated with male age and strict morphology on semen analysis. Other studies have also shown an effect of male age. Aging may be related to subtle or frank DNA fragmentation, as a number of studies have shown increased fragmentation with age. Antioxidants and frequent ejaculations prior to producing the specimen for the IVF cycle is advisable, particularly for males over age 40.
