Ovulation vs. Menstruation
Main DifferenceThe main difference between ovulation and menstruation is that ovulation is the release of eggs from the female ovary while the menstruation is the regular discharge of mucosal tissues and blood from the inner lining of the uterus.

Difference Between Ovulation and Menstruation
Ovulation vs. Menstruation
Ovulation is the ejaculation of egg or ova from the female ovary whereas the menstruation is the shedding of the endometrium, debris mucus tissues or blood from the uterus lining.
Ovulation vs. Menstruation
Ovulation takes place on the 14th day of the menstruation cycle whereas the menstruation takes place at the beginning of the menstruation cycle.
Ovulation vs. Menstruation
In ovulation, the temperature of the body increases while in the case of menstruation temperature of body decreases.
Ovulation vs. Menstruation
In ovulation, luteinizing hormone, follicle stimulating hormone, and estrogen hormone levels are high while in menstruation, levels of follicle stimulating hormone, luteinizing hormone, progesterone, and estrogen hormone are low.
Ovulation vs. Menstruation
Ovulation takes place in the mid of the menstrual cycle on the other side menstruation is the initial stage of the menstruation.
Ovulationnoun
(physiology) The release of an ovum from an ovary.
Menstruationnoun
The periodic discharging of the menses, the flow of blood and cells from the lining of the uterus in unfertilized females of humans and other primates.
Ovulationnoun
the expulsion of an ovum from the ovary (usually midway in the menstrual cycle)
Menstruationnoun
the monthly discharge of blood from the uterus of nonpregnant women from puberty to menopause;
the women were sickly and subject to excessive menstruationa woman does not take the gout unless her menses be stoppedthe semen begins to appear in males and to be emitted at the same time of life that the catamenia begin to flow in femalesComparison Chart

Ovulation vs. Menstruation
Ovulation is the release of an ova from the female ovary while the menstruation is the release of debris or blood from the uterus lining. Ovulation starts at the 14th day of the menstruation cycle whereas the menstruation starts at the beginning of the menstruation cycle. In ovulation, body temperature increases while in the case of menstruation body temperature decreases. Ovulation takes place in the mid of the menstrual cycle on the other side menstruation is the initial stage of the menstruation. In ovulation, levels of luteinizing hormone, follicle stimulating hormone, and estrogen hormone are high while in menstruation, levels of follicle stimulating hormone, luteinizing hormone, progesterone, and estrogen hormone are low.
What is Ovulation?
Ovulation is the ejaculation of ova in the middle of every menstrual cycle. It contains the release of a mature egg from the female ovary and pushing it down via the Fallopian tubes in order to make the egg available for fertilization. In humans, a single ovary is able to mature only an egg per one time. FSH (stimulating follicle hormone) which is a type of gonadotrophin and released by the anterior pituitary is responsible for the development of an egg. Follicle stimulating hormone is also responsible for stimulating the production of estrogen hormone from the ovary. Estrogen hormone is actually responsible for preparing the uterus for further fertilization events. At the beginning of the menstruation cycle level if estrogen hormone is low, but then the level of estrogen hormone gradually increases with the development of follicle. Very increased level of estrogen hormone may stimulate the production of fertile cervical mucus. The rapid increase of the LH (luteinizing hormone) is responsible for the rupture of the developing follicle by releasing the egg as the released egg from the female ovary cannot survive more than 24 hours inside the female reproductive system. Hence the ovulation day is the more appropriate day of fertile egg in the menstruation cycle. But the male’s sperm can survive in the female reproduction system for three to five days. The fertile period is also called the fertile window. The ruptured egg present in the ovary starts to produce progesterone that builds up the uterus walls.
What is Menstruation?
Menstruation is that periodical process of releasing the debris materials of the endometrium (inner lining of the uterus) along with the unfertilized egg or ova. It takes place at the beginning of every menstrual cycle. This phenomenon takes place only in females. It is most often known as the period. In females, the period lasts for about two to seven days. The duration of periods depends on the women’s diet, stress, health, and underlying illness. Many types of hormones regulated this phenomenon. In the uterus, if the egg is not fertilized, then the levels of both progesterone and estrogen hormone drop gradually. In the low levels of these hormones, the inner lining of the uterus starts to break. This lining begins to break along with the blood as menstrual flow. The first day of the menstruation cycle is known as the first day of the next menstruation cycle. Average menstruation cycle lasts for 28 days. Menstruation cycle also affects the temperature of women as the temperature decreases in the menstruation cycle.
The day of ovulation and the length of the menstrual cycle is directly related. Menstruation starts at 14 days after the ovulation, and the duration of the menstrual cycle can be 21 to 42 days, and its duration depends on the individual. The important role of menstruation is to prepare the uterus wall for the next menstrual cycle.
ConclusionThe conclusion of this article is that both ovulation and menstruation occur in the female body. Ovulation is the release of ova or egg from the female’s ovary whereas the menstruation is the shedding of the endometrium (the wall of the uterus), the release of mucosal tissues, debris, and blood from the lining of the uterus.
