Difference Between Ovulation and Menstruation

Ovulation vs Menstruation
 

The menstruation cycles, also referred to as reproductive cycle involves ovulation and menstruation. It varies from one woman to another, and occurs first when a girl becomes sexually matured at puberty. Ovulation occurs during the ovarian cycle and menstruation occurs during the endometrial cycle and these two cycles occur simultaneously. This is a vital and complex process that occurs in female reproductive system, and it encircles an intricate series of chemical secretions and reactions to produce the ultimate potential for fertility and new birth. The length of the menstruation cycle is measured from day 1 of one cycle to day 1 of the next cycle. The duration of normal menstruation cycle is around 21 days to 36 days.

Ovulation

The release of an ovum from an ovary is known as ovulation. It occurs only once in every menstruation cycle. Regardless of the length of the menstruation cycle, ovulation always occurs 14 days before menstruation. During the time of ovulation, there is an increment of cervical mucus secretion due to the increased levels of estrogen. During the ovulation period, the mucus pH increases and becomes clear, slippery, and stretchy fluid. This alkaline pH of mucus increases the sperm morality and longevity at this period. Therefore, this is the time in the cycle when a woman can easily become pregnant.

Menstruation

Menstruation is the cyclic discharge of the blood-enriched endometrium through the vagina when pregnancy does not occur. It is a normal, predictable, physiological process that basically results in the absence of fertilization. Menstruation begins when the pituitary gland secretes FSH and LH hormones. FSH stimulates the growth of follicles in the ovary while LH stimulates the ovary to release an ovulate. If the mature ovum is not fertilized after the ovulation, it results in lack of progesterone levels, in the blood. This triggers the discharge of the endometrium during the menstrual phase of menstruation cycle.

What is the difference between Ovulation and Menstruation?

• Ovulation is the release of a mature ovum from an ovary, whereas menstruation is the discharge of blood, broken uterine lining, and dead ovum from the body.

• Ovulation takes place 14 days before menstruation in the reproductive cycle, whereas menstruation marks the beginning and end of menstruation cycle.

• Unlike the ovulations, the absence of fertilization results in next menstruation.

• Ovulation occurs in the ovulation cycle, whereas menstruation occurs during the endometrial cycle.

• The duration of menstruation is longer than that of ovulation.

• Unlike the ovulation, menstruation creates uncomfortable feelings, pains, cramps, emotional disturbances, headaches, and unusual tiredness due to the heavy bleeding through the vagina.
