In these animals, eCG induces ovulation of the largest and most functional follicle, which therefore will develop a better corpus luteum (CL), increasing progesterone, which favors embryonic development and survival (RENSIS & LOPEZ-GATIUS, 2014).
It was demonstrated that Sfrp4 (the rat ortholog of human SFRP-4) is highly expressed in luteinized mouse GCs (12) The role of sFRP-4 in luteinization events is further highlighted by its down regulation in Fzd4-null mice leading to altered corpus luteum development and subsequent infertility (13).
The optimal time for surgical intervention is after the first trimester as organogenesis is largely complete, therefore minimizing the risk of drug-induced teratogenesis, and any necessary cystectomy or oophorectomy will not disrupt the required progesterone production of the corpus luteum as this has been replaced by the placenta.
