OVULATION Meaning and
Definition
-
Ovulation refers to a natural physiological process that is primarily associated with the female reproductive system in mammals, including humans. It is a crucial event in the menstrual cycle of females in which a mature egg or ovum is released from one of the ovaries into the fallopian tube.
Ovulation typically occurs halfway through the menstrual cycle, usually around day 14 in a typical 28-day cycle. It is preceded by a surge in luteinizing hormone (LH) production from the pituitary gland, which triggers the release of the egg from the dominant follicle within the ovary. The release of the egg allows it to become available for fertilization by sperm.
During ovulation, the ovum is released into the abdominal cavity and is then swept into the fallopian tube by finger-like projections called fimbriae. Once in the fallopian tube, the ovum may be fertilized by sperm if intercourse occurs during this time. If fertilization occurs, the resulting embryo will travel down the fallopian tube, eventually reaching the uterus for implantation and pregnancy.
If fertilization does not occur, the ovum is not viable and is usually absorbed by the body. Following ovulation, the released follicle transforms into the corpus luteum, a temporary endocrine gland that produces hormones such as progesterone, assisting in preparing the uterus for potential pregnancy.
Understanding ovulation is important for various purposes such as fertility tracking, family planning methods, and assisted reproductive technologies.
