OVARIAN CYCLE Meaning and
Definition
-
The ovarian cycle refers to the regular series of physiological events that occur within the ovaries of female mammals, including humans, during their reproductive years. It encompasses the process of folliculogenesis, ovulation, and luteinization, which collectively oversee the development and release of eggs (or ova) from the ovaries. The ovarian cycle, usually lasting around 28 days in humans, is hormonally regulated and tightly synchronized with the menstrual cycle.
Initiated by the release of follicle-stimulating hormone (FSH) from the pituitary gland, the ovarian cycle commences with the recruitment and maturation of ovarian follicles. These follicles contain immature eggs and are stimulated to grow by the increasing levels of estrogen. Eventually, one dominant follicle emerges and reaches maturity, while the others regress. This mature follicle then ruptures during ovulation, releasing the egg into the fallopian tube, where it awaits fertilization.
The luteal phase follows ovulation and is characterized by the transformation of the ruptured follicle into a corpus luteum, which secretes progesterone and some estrogen. These hormones play a vital role in preparing the uterus for potential pregnancy. If fertilization and implantation of an embryo do not occur, the corpus luteum eventually degenerates, initiating menstruation and marking the beginning of a new ovarian cycle.
The regulation of the ovarian cycle involves a delicate interplay of hormones, including FSH, luteinizing hormone (LH), estrogen, and progesterone. Disruptions in the ovarian cycle can lead to various reproductive conditions and menstrual irregularities, necessitating medical attention.

Etymology of OVARIAN CYCLE
The word "ovarian" is derived from the Latin word "ovarius", which means "pertaining to the egg". It is a combination of "ovum", meaning "egg", and the suffix "-arius", indicating connection or relationship.
The word "cycle" is derived from the Greek word "kyklos", which means "circle" or "cycle". It refers to a recurring sequence of events or a period that repeats itself in a predictable manner.
Therefore, the term "ovarian cycle" combines the Latin term for "egg" with the Greek term for "cycle", resulting in a phrase that describes the recurring sequence of events and changes that occur in the ovaries of female organisms.
