The female reproductive system


Anatomy of the female reproductive system

Reproductive system The female urogenital tract consists of all the organs involved in reproduction and the formation and release of urine. It includes the kidneys, ureters, bladder, urethra, and the organs of reproduction: uterus, ovaries, fallopian tubes and vagina. The uterus is the major female reproductive organ.

For more information on the anatomy of the reproductive system, see Female Urogenital System and Male Urogenital System.

Menstruation

Menstruation Menstruation involves ovulation and shedding of the endometrium in a cyclical fashion in an attempt to release an unfertilised egg ready for fertilisation when in the presence of sperm. The cycle has an average duration of 28 days, but the normal range is between 21 to 35 days.

For more information, see Menstruation.

About pregnancy


Pregnancy planning (preconception advice)

Preconception advice Knowing the basic physiology of pregnancy can increase a woman’ chances of becoming pregnant. For those who are trying to conceive, the best time to have sexual intercourse is around the time of ovulation. This is usually on day 14 of the menstrual cycle, but it varies amongst women.

For more information on how to prepare for pregnancy, see Pregnancy Planning (Preconception Advice).

 
Pregnancy investigations

Obstetric ultrasound Pregnancy investigations are procedures used to diagnose complications or foetal abnormalities. Amniocentesis involves inserting a needle into the uterus to withdraw a sample of amniotic fluid. Other diagnostic procedures may be offered, including an obstetric ultrasound, and chorionic villus sampling.

For more information, see Pregnancy Investigations.

Stages of pregnancy

Stages of pregnancy The first trimester of pregnancy is when the major organ systems of the foetus begin the develop. By the eighth week after fertilisation, all organs are present. The second trimester is a period of rapid relative growth. The third trimester is when the foetus builds muscle and fat to increase body weight.

For more information on foetal development and maternal changes during pregnancy, see Stages of Pregnancy.

Symptoms in pregnancy

Symptoms in pregnancy Pregnancy induced nausea and vomiting or ‘morning sickness’ is a very common symptom of pregnancy. Other symptoms such as abdominal pain and vaginal bleeding may be indicative of miscarriage, ectopic pregnancy, molar pregnancy, placenta praevia or abruptio placenta.

For more information, see Symptoms in Pregnancy.

Complications of pregnancy

Complications of pregnancy Pregnancy is a normal and natural event. However, it may pose risks to the mother. If implantation occurs anywhere outside the uterus, then the result is an ectopic pregnancy. Other complications of pregnancy are placenta praevia, placental abruption, preeclampsia, which increases the risk of cardiovascular problems, or premature delivery.

For more information, see Complications of Pregnancy.

Termination of pregnancy

Abortion If a woman chooses not to pursue a pregnancy, she may terminate it by having an abortion. An abortion is a surgical procedure to remove the contents of the uterus. Late term abortions are usually not possible unless there is a risk to the woman’s health, or the foetus has a serious medical condition.

For more information, see Abortion.

Lifestyle during pregnancy

Living with pregnancy Nutritional requirements change during pregnancy. Pregnant women should avoid foods that are more likely to contain harmful pathogens (e.g. processed meats). Alcohol, caffeine, tobacco smoke and certain drugs may affect foetal development and should also be avoided. Pregnancy is also a critical time to focus on good dental hygiene and safe exercise.

For more information, see Lifestyle During Pregnancy.

Birth and postnatal information


Birth

Labour Pregnancy comes to an end with birth, the expulsion of the foetus through the woman’s vagina. Women who are soon to give birth will experience contractions, which gradually become more frequent and regular. When the cervix has fully dilated, the woman may feel an urge to push.

For more information, seeBirth.

Life after childbirth

Postpartum period The postnatal period is a time of major change for a family. Women’s hormones and weight are rapidly readjusting, lifestyles and relationships are changing, and the baby needs constant attention. Breastfeeding provides nourishment to an infant and is recommended for at least 6 months exclusively.

For more information, see Life After Childbirth.
