A nabothian cyst (or nabothian follicle) [1] is a mucus-filled cyst on the surface of the cervix. They are most often caused when stratified squamous epithelium of the ectocervix (portion nearest to the vagina) grows over the simple columnar epithelium of the endocervix (portion nearest to the uterus). This tissue growth can block the cervical ...
The cervix (pl.: cervices) or cervix uteri is a dynamic fibromuscular sexual organ of the female reproductive system that connects the vagina with the uterine cavity. [1] The human female cervix has been documented anatomically since at least the time of Hippocrates, over 2,000 years ago.
Blood tests for the level of hormones such as follicle-stimulating hormone, luteinizing hormone, estrogen, prolactin, insulin may be conducted. In polycystic ovarian syndrome, there will be high levels of insulin and androgens. An ultra sonogram can diagnose the thickness of the endometrium, size of the ovaries growth of follicles, ovulation ...
Gartner's duct is located in the uterus' broad ligament. Its position is parallel with the lateral uterine tube and lateral walls of vagina and cervix . The paired mesonephric ducts in the male , in contrast, go on to form the paired epididymides , vasa deferentia , ejaculatory ducts and seminal vesicles .
The follicle first forms a corpus hemorrhagicum before it becomes a corpus luteum, but the term refers to the visible collection of blood, left after rupture of the follicle, that secretes progesterone. While the oocyte (later the zygote if fertilization occurs) traverses the fallopian tube into the uterus, the corpus luteum remains in the ovary.
Also in the cortex is the corpus luteum derived from the follicles. The innermost layer is the ovarian medulla. [8] It can be hard to distinguish between the cortex and medulla, but follicles are usually not found in the medulla. Follicular cells are flat epithelial cells that originate from surface epithelium covering the ovary.
Follicles that have fewer FSH-receptors will not be able to develop further; they will show retardation of their growth rate and become atretic. Eventually, only one follicle will be viable. This remaining follicle, called the dominant follicle, will grow quickly and dramatically—up to 20 mm in diameter—to become the preovulatory follicle.
Follicular waves are best described as the phase when follicles have matured sufficiently and rupture, leading to ovulation. Recent findings into the menstrual cycle in mammals has discovered that 2 or more follicles can develop but only one of the follicles fully matures to release the egg.
