Effects of advanced paternal age on fertility

Owing to sociocultural and economic factors, there has been a considerable increase in recent years in the number of men over the age of 35 who wish to have children. As a couple ages, the probability that they will experience reproductive problems increases. The negative effect of maternal age on fertility has been widely documented and we know that fertility diminishes drastically after the age of 39. Maternal aging is also associated with miscarriage, pregnancy complications, congenital anomalies and an increase in perinatal mortality.
However, few studies analyse the effect of  paternal age on success after the application of assisted reproduction technology (ART) and the results they provide are contradictory. It is true that the male reproductive function is less vulnerable than the female where the aging process is concerned, as is demonstrated by the fact that many babies have been born spontaneously to fathers who are in their seventies or eighties. However, some associations have been found in specific studies that relate a negative effect of advanced paternal age with: […]

When only a few fertilised oocytes are available as a result of poor ovarian reserve, transfer is carried out on day 2 or 3 of development in around 60% of cases because at this stage we can clearly select the embryos that are suitable for transfer. In around half of these cases it is not possible to cryopreserve embryos for future attempts. […]

Antioxidant-rich diet and improved male fertility

Around 8 million people around the world have infertility problems. Delayed conception affects about 15% of all couples trying to get pregnant. However, slight/moderate male factors that produce sub-fertility in couples are estimated to represent about 50% of all cases. Tremellen confirms that 1 in 20 men will be sub-fertile (Tremellen, 2008).
