Everything You Need To Know About Ovulation

Ovulation refers to the release of an egg during menstruation in females.

Part of the ovary called the ovarian follicle discharges an egg. The egg is also known as an ovum, oocyte, or female gamete. It is only released on reaching maturity.

After release, the egg travels down the fallopian tube, where it may be met by a sperm and become fertilized.

Ovulation and hormonal release during the menstrual cycle are controlled by a part of the brain called the hypothalamus. It sends signals instructing the anterior lobe and pituitary gland to secrete luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

It is useful to know when ovulation is likely to occur, as a woman is most fertile during this time, and more likely to conceive.

Phases

1.The periovulatory or follicular phase: A layer of cells around the ovum begins to mucify, or become more like mucus, and expand. The uterus lining begins to thicken.

2.The ovulatory phase: Enzymes are secreted and form a hole, or stigma. The ovum and its network of cells use the stigma to move into the fallopian tube. This is the period of fertility and usually lasts from 24 to 48 hours.

3.The postovulatory or luteal phase: LH is secreted. A fertilized egg will be implanted into the womb, while an unfertilized egg slowly stops producing hormones and dissolves within 24 hours.

When does it occur?

A woman's menses lasts on average between 28 and 32 days.

The beginning of each cycle is considered to be the first day of the menses. Release of the egg generally occurs 12 to 16 days before the next period is due.

Most women begin to menstruate between the ages of 10 to 15 years. At the same time, they begin to ovulate and become able to conceive. This is a time referred to as the menarche.

Ovulation typically stops after menopause, between the ages of around 50 to 51 years on average, but it still occurs in the time leading up to menopause. This is referred to as peri-menopause.

Detection

There are several indications that a woman is ovulating.

During ovulation, the cervical mucus increases in volume and becomes thicker due to increased estrogen levels. The cervical mucus is sometimes likened to egg whites at a woman's most fertile point.

There may also be a slight increase in body temperature. This is driven by the hormone progesterone, which is secreted when an egg is released. Women are generally most fertile for 2 to 3 days before the temperature reaches its maximum.

A basal thermometer can be used to track the subtle temperature increase. These can be purchased online or at most drug stores.

Some women feel a mild ache or pang of pain in the lower abdomen. This is called Mittelschmerz pain. It may last between a few minutes and a few hours.

Finally, ovulation predictor kits, available from drug stores, can detect the increase in luteinizing hormone (LH) in the urine just before ovulation.

Disorders

Issues with the ovulation process can lead to infertility or difficulty conceiving.

1.Polycystic ovarian syndrome: A woman with polycystic ovarian syndrome (PCOS) has enlarged ovaries, often with small, fluid-filled cysts on them. It can lead to a hormone imbalance that can disrupt ovulation.

Other symptoms can include insulin resistance, obesity, abnormal hair growth, and acne.

PCOS is the leading cause of infertility in women.

2.Hypothalamic dysfunction: This happens when the production of the FSH and LH hormones is disrupted. These are the hormones that stimulate ovulation. This can affect the menstrual cycle.

Irregular menstrual cycles and amenorrhea, which means not menstruating at all, are common.

Causes of hypothalamic dysfunction include excessive physical or emotional stress, extremely high or low body weight, or substantial weight gains or losses.

Excessive exercise, low body weight, and tumors of the hypothalamus can also lead to hypothalamic dysfunction.

3.Premature ovarian insufficiency: This is when egg production stops prematurely, due to a drop in estrogen levels.

It can be due to an autoimmune disease, genetic abnormalities, or environmental toxins.

It typically affects women before the age of 40 years.
