Ovulation and Menstruation

When a mature egg is released from the ovary, it is ovulation. The egg then moves to the fallopian tube, where it is fertilized. If the sperms are present in the tube when the egg gets released, there is a good chance to conceive, which creates an embryo.

Ovulation

• At the time of the follicular phase, the rising estrogen levels trigger the pituitary glands to release the LH (luteinizing hormone). This commences the process of ovulation.
• The process of ovulation causes the release of the mature egg, which travels down the fallopian tube towards the uterus for fertilization (in case sperm is present).
• This is the only time during the menstrual cycle when one can conceive.
• Some of the symptoms of the phase of ovulation are – slight rise in the basal temperature of the body and thicker discharge which has the egg white’s texture.
• One ovulates at around the 14th day in the case of a 28-days cycle – i.e., right at the middle of the menstrual cycle and it lasts for close to 24 hours.
• A day after this, the egg dissolves or dies in case it was not fertilized.

Menstruation

• It is the monthly shedding of the uterine lining in a woman and is referred to by several names – menstrual period, menses, menstrual cycle or period.
• The menstrual blood is a mix of tissue and blood from inside the uterus, flowing from the uterus through the cervix, finally exiting the body through the vagina.
• The menstrual cycle is distinguished by the rise and decline of hormones.
• It is triggered by the falling levels of progesterone and is a sign that pregnancy has not taken place.
