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 ...
Various body parts have diverse microorganisms. Some microbes are specific to certain body parts and others are associated with many microbiomes. This article lists some of the species recognized as belonging to the human microbiome and focuses on the oral, vaginal, ovarian follicle, uterus and the male reproductive tract microbiota.
This type can form when ovulation doesn't occur, and a follicle doesn't rupture or release its egg but instead grows until it becomes a cyst, or when a mature follicle involutes (collapses on itself). It usually forms during ovulation, and can grow to about 7 cm in diameter.
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.
In the ovaries, the developing egg cells (or oocytes) mature in the fluid-filled follicles. Typically, only one oocyte develops at a time, but others can also mature simultaneously. Follicles are composed of different types and number of cells according to the stage of their maturation, and their size is indicative of the stage of oocyte ...
The uterus and endometrium was for a long time thought to be sterile. The cervical plug of mucosa was seen to prevent the entry of any microorganisms ascending from the vagina. In the 1980s this view was challenged when it was shown that uterine infections could arise from weaknesses in the barrier of the cervical plug.
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.
