Sperm quality and women’s age have the most significant effect on fertility success, say researchers.
A new study has indicated that the age of the sperm donor may not be the reason of a failed chance at fertility resulting from treatment using donor sperms. The reason may be, in fact, the age of the women receiving the treatment.
In general cases too, it might be the age of women rather than that of men that decides the success rate of fertility.
The report also suggests that the quality of sperms matters for chances of fertility and not the age of the male donating or producing them.
The study was undertaken at the Newcastle Fertility Centre, United Kingdom. The study involved the analysis of 39,000 first fertility treatment trials performed in the United Kingdom between 1991 and 2012. The treatments studied were either donor insemination or in-vitro fertilization (IVF).
The rate of success in IVF treatment was found to be 29% in women aged between 18 and 34. The success rates were only 14 percent in women aged over 37 years. However, no link was found between success rates of any fertility treatment in these two age groups and the age of the sperm donor.
The researchers say that no substantial effect is seen on the outcome of any fertility treatment due to the age of the male donor, at least until the age of 45.
