What is Ovulation?

Ovulation is the time in the female menstrual cycle when an ovarian follicle discharges an ovum. During this period, the ovum travels through the fallopian tube. If it meets a sperm there, it would be fertilized.

It is controlled by hypothalamus, a part of the brain that sends signals to the pituitary gland and anterior lobe to begin secreting follicle stimulating hormones and luteinizing hormones. This happens between 10th & 19th day of the menstrual cycle for most women. So basically, ovulation is the time when women are the most fertile.

Ovulation phases

During ovulation, your hormones would be elevated. It can be divided in three stages, though these stages often overlap.

• Periovulatory phase: A cell layer is formed around the egg, and it starts to become more like mucous. It expands and the lining of the uterus thickens.

• Ovulatory phase: Some enzymes are secreted and they make a hole that is used by the egg to leave the follicle. Then it enters the fallopian tube. That’s the fertility period that lasts for about 24-48 hours.

• Postovulatory phase: This part of ovulation involves the secretion of luteinizing hormones (LH). If the egg is fertilized, it will be implanted in the womb. The unfertilized egg, however, stops generating hormones. Then the uterus lining begins to break down and exits the body during menstruation.

When does ovulation happen?

The menstrual cycle generally lasts for 28-32 days. This is just an average figure, and some women have shorter or longer menstrual periods than this. Ovulation occurs between the 10th & 19th day of this cycle.

How to know when you are ovulating?

There are many ways to know when you are ovulating. You will notice that you have more cervical mucus than usual. It even becomes thicker because of high estrogen levels. At your most fertile point, the cervical mucus will resemble egg white.

Ovulation might also raise your body temperature by 0.4o to 1.0o. This temperature rise is because of progesterone hormone, which is produced as the ovum is released. Women stay the most fertile for 2-3 days before the temperature reaches the maximum point.

There are some women who can sense ovulation in their mid section. It can be a pang of pain or just a mild ache. This condition is known as mittelschmerz. It can last for a few hours or a couple of minutes.
