The menstrual cycle is the regular natural change that occurs in the female reproductive system (specifically the uterus and ovaries) that makes pregnancy possible.

The cycle is required for the production of ovocytes, and for the preparation of the uterus for pregnancy.

Up to 80% of women report having some symptoms during the one to two weeks prior to menstruation.

Common symptoms include acne, tender breasts, bloating, feeling tired, irritability and mood changes.

These symptoms interfere with normal life and therefore qualify as premenstrual syndrome in 20 to 30% of women.

In 3 to 8%, they are severe.

A hormone (from the Greek participle “”) is any member of a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behaviour.

Hormones have diverse chemical structures, mainly of 3 classes: eicosanoids, steroids, and amino acid/protein derivatives (amines, peptides, and proteins).

The glands that secrete hormones comprise the endocrine signaling system.

The term hormone is sometimes extended to include chemicals produced by cells that affect the same cell (autocrine or intracrine signalling) or nearby cells (paracrine signalling).

Pregnancy, also known as gravidity or gestation, is the time during which one or more offspring develops inside a woman.

A multiple pregnancy involves more than one offspring, such as with twins.

Pregnancy can occur by sexual intercourse or assisted reproductive technology.

Childbirth typically occurs around 40 weeks from the last menstrual period (LMP).

This is just over nine lunar months, where each month is about 29½ days.

When measured from conception it is about 38 weeks.

An embryo is the developing offspring during the first eight weeks following conception, after which, the term fetus is used until birth.

Symptoms of early pregnancy may include missed periods, tender breasts, nausea and vomiting, hunger, and frequent urination.

Pregnancy may be confirmed with a pregnancy test.

Fertility is the natural capability to produce offspring.

As a measure, fertility rate is the number of offspring born per mating pair, individual or population.

Fertility differs from fecundity, which is defined as the potential for reproduction (influenced by gamete production, fertilization and carrying a pregnancy to term).

A lack of fertility is infertility while a lack of fecundity would be called sterility.

A woman is a female human.

The term woman is usually reserved for an adult, with the term girl being the usual term for a female child or adolescent.

The term woman is also sometimes used to identify a female human, regardless of age, as in phrases such as "women's rights".

Women with typical genetic development are usually capable of giving birth from puberty until menopause.
