Physiology of uterus


The uterus is a unique organ in the female reproductive tract. Its cyclicity is obvious in its shedding its inner layers once a month. The two top layers (strata compactum, and spongiosum) are supplied by the spiral arterioles which constrict at the time of sex steroid withdrawal (i.e. low levels) which occur at the end of a cycle. The uterus is also thought to produce steroids on its own rights, including peptides hormones such as LH and FSH. The functions of these peptide hormones in the uterus is not fully understood, but they may assist the process of local control of reproduction or in the production of exocrine secretions such as are produced in the uterine glands which aid the early process of implantation
