Is late-follicular phase progesterone rise associated with a deleterious on embryo quality?
Previous studies have shown that late follicular phase progesterone elevation may adversely affect pregnancy outcomes in IVF/ICSI cycles. Although most of the studies supported a potential detrimental effect of progesterone elevation on implantation rates, recent reports support a potential detrimental effect of progesterone elevation on embryo quality.
