Abstract
Hormonal contraceptives are unsuitable for many women; thus, the development of new, nonhormonal contraceptives is of great interest. In women, uterine epithelial expression of interleukin 11 (IL11) and its receptor (IL11RA) suggests IL11 is critical for blastocyst attachment during implantation. Il11ra-deficient mice are infertile due to a defective decidualization response to the blastocyst, leading to total pregnancy loss. We examined the effect of administering a PEGylated IL11 antagonist, PEGIL11A (where PEG is polyethylene glycol), on pregnancy outcomes in mice and IL11 signaling in human endometrial epithelial cells (HES). PEGIL11A was detected in sera up to 72 h after intraperitoneal..
