Binding sites for LH/hCG and/or its mRNA are found in the uterus of several species, including human, primate, pig, cow, and turkey. Activation of LH receptors around Day 15 of the estrous cycle is associated with increased prostaglandin F(2alpha) production in the bovine, porcine, and ovine uterus. Activation of uterine LH receptors is also associated with increased levels of prostaglandins in human and primate. The presence of gonadotropin receptors with a dynamic pattern in the oviduct, endometrium, myometrium, and cervix of different species provides evidence that gonadotropins play a substantial role in molecular autocrine-paracrine regulation of the estrous cycle and implantation.

UI	MeSH Term	Description	Entries
D009215	Myometrium	The smooth muscle coat of the uterus, which forms the main mass of the organ.	Uterine Muscle,Muscle, Uterine,Muscles, Uterine,Uterine Muscles
D011974	Receptors, LH	Those protein complexes or molecular sites on the surfaces and cytoplasm of gonadal cells that bind luteinizing or chorionic gonadotropic hormones and thereby cause the gonadal cells to synthesize and secrete sex steroids. The hormone-receptor complex is internalized from the plasma membrane and initiates steroid synthesis.

D002584	Cervix Uteri	The neck portion of the UTERUS between the lower isthmus and the VAGINA forming the cervical canal.

D004717	Endometrium	The mucous membrane lining of the uterine cavity that is hormonally responsive during the MENSTRUAL CYCLE and PREGNANCY. The endometrium undergoes cyclic changes that characterize MENSTRUATION. After successful FERTILIZATION, it serves to sustain the developing embryo.	Endometria
D005187	Fallopian Tubes	A pair of highly specialized canals extending from the UTERUS to its corresponding OVARY. They provide the means for OVUM transport from the ovaries and they are the site of the ovum's final maturation and FERTILIZATION. The fallopian tube consists of an interstitium, an isthmus, an ampulla, an infundibulum, and fimbriae. Its wall consists of three layers: serous, muscular, and an internal mucosal layer lined with both ciliated and secretory cells.

D005836	Genitalia, Female	The female reproductive organs. The external organs include the VULVA; BARTHOLIN'S GLANDS; and CLITORIS. The internal organs include the VAGINA; UTERUS; OVARY; and FALLOPIAN TUBES.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D000829	Animals, Domestic	Animals which have become adapted through breeding in captivity to a life intimately associated with humans. They include animals domesticated by humans to live and breed in a tame condition on farms or ranches for economic reasons, including LIVESTOCK (specifically CATTLE; SHEEP; HORSES; etc.), POULTRY; and those raised or kept for pleasure and companionship, e.g., PETS; or specifically DOGS; CATS; etc.	Farm Animals,Domestic Animals,Domesticated Animals,Animal, Domestic,Animal, Domesticated,Animal, Farm,Animals, Domesticated,Animals, Farm,Domestic Animal,Domesticated Animal,Farm Animal
