Human chorionic gonadotropin (hCG) is a hormone for the maternal recognition of pregnancy produced by trophoblast cells that are surrounding a growing embryo (syncytiotrophoblast initially), which eventually forms the placenta after implantation. In the reproductive tract of human males, RLN is mainly produced by the prostate and secreted into the seminal fluid, where it seems to play a role in sperm function. The corpus luteum also secretes a small amount of relaxin in the terminal stages of pregnancy. Blood inhibin levels were reduced in 104 men with various testicular disorders as compared to normal men [ 19, 20 ]. Relaxin: It is a hormone secreted by the ovaries and placenta. Relaxin, a hormone usually associated with pregnancy, has been found in the semen plasma of many species. LH is a type of glycoprotein that is produced in the anterior pituitary via gonadotroph cells and serves to regulate the function of the gonads. In the male, inhibin B is produced in the testis, principally by the Sertoli cells. More so, scientist refers to use animals, such as guinea pigs and mice to conduct the effects and functions of the relaxin hormone. Maximal concentrations are attained by days 40 to 50 of pregnancy and are followed by slight declines before parturition. Relaxin is a protein-based hormone usually secreted by the corpus luteum (which is a hormone-producing structure) in the ovary. In the male and the female, the target tissue is the .

The relaxin-like peptide family belongs in the insulin superfamily and consists of 7 peptides of high structural but low sequence similarity; relaxin-1 (RLN1), 2 (RLN2) and 3 (), and the insulin-like (INSL) peptides, INSL3, INSL4, INSL5 and INSL6.The functions of relaxin-3, INSL4, INSL5, and INSL6 remain . 3 A woman's blood volume may increase by 30% to 50% during pregnancy. Relaxin is a hormone structurally related to insulin and insulin-like growth factor, which exerts its regulatory effect on the musculoskeletal and other systems through binding to its receptor in various tissues, mediated by different signaling pathways. The innermost layer of the uterine wall is the endometrium, which undergoes marked changes during the menstrual cycle.
