Luteal Phase Support
Also written as: LPS — Luteal Phase Support
Hormonal supplementation following embryo transfer to support early pregnancy.
Full Definition
Luteal phase support involves the administration of progesterone and sometimes estrogen following embryo transfer to compensate for the luteal phase deficiency that commonly occurs after controlled ovarian stimulation. The medications help maintain the endometrial lining and support implantation and early embryo development. LPS typically begins on the day of egg retrieval or embryo transfer and continues for 8-12 weeks of pregnancy if conception occurs. Common formulations include vaginal suppositories, gels, intramuscular injections, and oral preparations.
Usage
Usage note: Specify the route of administration and dosing when documenting LPS protocols.
