The Age of Onset of Menopause

The norm age of oncoming of climacteric depends on race, household history and a figure of other factors different in each woman. Although the normal age of climacteric can change between 45 old age to 55 years, the norm age of climacteric is 51 years. Surgical menopause, of course, can happen at any clip the womb is surgically removed.

All women are born with a finite figure of follicles that are determined genetically. Menopause happens when this stock of follicles are exhausted at the end of the generative life.

It is estimated that there are about 7 million primary oocytes or primary follicles in a 24 hebdomad old fetus. These lessening to about 2 million at birth. Of these lone about 500 follicles are destined to develop into mature Graafian Follicles. The remainder are lost through degeneration.

The age of climacteric depends to some extent on whether a adult female ovulates (releases an ovum) every month. Most adult female make not. Certain factors like the figure of children a adult female have given birth to, the old age spent breastfeeding, old age of taking birth control pills (the pills halt ovulation) - each of these factors forestall ovulation and assist construct up the stock of follicles. This holds menopause.

During gestation , that is for 9 months, there is no ovulation. Normally, at least 5 -6 follicles develop in each catamenial rhythm during the non-pregnant state. So, each gestation intends that these follicles stay in extra in the ovaries. The adult female who have got been pregnant more than often, will thus have a bigger stock of follicles in her ovaries and will thus menstruate for a longer time.

Ovulation is also arrested in some women during the first 5 – 6 calendar months of active breastfeeding. So, gestation and breastfeeding are likely to detain the oncoming of the age of menopause.

Birth control pills incorporate internal secretions that tin block the procedure of oocyte maturation. Ovulation is thus prevented every month. This volition aid in preventing the lessening in the figure of oocytes in the ovaries.

One of import factor that should be noted is that deficiency of ovulation makes not forestall the ageing of oocytes within the ovary. Over time, oocytes will go on to be lost, even when there is no ovulation as in pregnancy, breastfeeding and taking of birth control pills. But this loss is substantially less than the loss that happens when ovulation is actually taking place.

There are other factors that also impact the age of oncoming of menopause. Women with the same ethnical background acquire their climacteric at about the same time. For example, Nipponese women are known to acquire their climacteric later than women with African ancestors. This is probably because of a similar familial component.

Stress, obesity, environmental factors, nutritionary lacks can all impact the age of oncoming of menopause. It have even been suggested that climactic statuses can impact the norm age of oncoming of menopause. Women of colder climes generally acquire their climacteric at a future age than women of tropical climates. But this is also probably owed to a similar familial composition of the women who remain at the same place(either colder or warmer clime ) together.

The norm age of oncoming of climacteric thus depends not only on the familial constitution of the adult female concerned as well as on other factors which influence her life.
