In a nutshell This study investigated live birth rates (LBRs) in women that underwent frozen (Fz) embryo transfer (ET). They found that LBRs were higher with Fz-ET in women under 35, but there was no difference between Fz and fresh (Fr) ET in those older than 35. Some background Infertility is a common condition. Assisted reproductive technology...

In a nutshell This study investigated if the DNA fragmentation index (DFI) is associated with fertility outcomes. They found that lower DFI was associated with better pregnancy rates (PRs). Some background Male infertility (MI) is a common cause of couple infertility. MI is involved in 30-50% of cases. Men with abnormal sperm...
