Sperm Donor Age Does Not Affect Birth Rate
(HealthDay News) — Among women undergoing assisted reproduction for the first time, the age of the sperm donor does not appear to significantly affect the live birth rate, according to research presented at the annual meeting of the European Society of Human Reproduction and Embryology, held from June 29 to July 2 in Munich.
Navdeep K. Ghuman, MD, and Meenakshi Choudhary, MD, PhD, of the Newcastle Fertility Centre in Newcastle upon Tyne, U.K., conducted a retrospective analysis of data for 39,282 first treatment cycles for donor insemination (DI) or in vitro fertilization (IVF). The researchers examined the effect of donor age for six subgroups (<20 years, 21–25 years, 26–30 years, 31–35 years, 36–40 years, and 41–45 years) on live birth rate among two age groups of women (18–34 years and >37 years).
The researchers found no significant effect of sperm donor age on the live birth rate resulting from DI or IVF in either group of women. A trend was observed for increased likelihood of live birth with increasing sperm donor age. The lowest chance of live birth appeared to be associated with sperm donors <20 years.
"Despite these trends, it's important to note that the impact of sperm donor age on live birth failed to reach statistical significance in any of the age groups we studied," Choudhary said in a statement.
