99 free Female Anatomy trivia questions with answers — science & nature quiz, new questions added Oct 2026.
This female anatomy trivia quiz covers the female body the way a good biology course would: the reproductive organs and how they work, the hormones that run the cycle, and the physical differences that show up in bones, blood and skin. It starts with the basics, such as the shape of the uterus, the layers of its wall, how many eggs a woman is born with, and what day one of the cycle actually is. From there it moves into ovulation, the corpus luteum, the three estrogens, progesterone, menopause and hot flashes. There are questions on the breast and lactation (prolactin versus oxytocin, colostrum, Cooper's ligaments), the pelvis and why it differs from a man's, the cervix in labour, the vaginal microbiome, the placenta and hCG, Barr bodies, and the anatomists whose names stuck: Falloppio, de Graaf, Bartholin, Skene. It is written for nursing and biology students, quiz nights and anyone curious about how the body works, in plain clinical language. Every answer has been checked against Wikipedia's medical articles, and each explanation adds one further fact worth remembering.

Q 01The human uterus is usually described as being shaped like which fruit?
A pear
A pear: it sits just behind and almost over the bladder, which is why a growing pregnancy makes women need to urinate more often.
Q 02What is the inner lining of the uterus, shed during a period, called?
Endometrium
Endometrium: each cycle it thickens to receive an embryo, and if none implants, the lining breaks down and leaves the body as a period.
Q 03The thick muscular wall of the uterus that contracts during childbirth is called what?
The myometrium
The myometrium: it stretches during pregnancy, letting the uterus grow to several times its usual size before it contracts in labour.
Q 04Roughly how many oocytes (immature eggs) are present in the ovaries at birth?
About 1 million
About 1 million: most of them die off naturally, so by puberty well over half are already gone.
Q 05Approximately how many eggs does a woman release over her whole reproductive life?
About 400
About 400: usually just one egg is released each menstrual cycle, so decades of cycles add up to only a few hundred.
Q 06Which test collects cells from the cervix to check for signs of cancer?
Pap smear
Pap smear: it spots precancerous changes before cancer develops, which is how cervical screening helps prevent the disease.
Q 07Fertilization normally happens in which part of the fallopian tube, its widest section?
The ampulla
The ampulla: from there, tiny hairs lining the tube sweep the fertilized egg, dividing as it goes, down into the uterus.
Q 08What are the finger-like projections at the end of each fallopian tube called?
Fimbriae
The egg is actually released into the abdominal cavity first; beating cilia on the fimbriae draw it into the tube.
Q 09What is the surgical removal of the uterus called?
Hysterectomy
Hysterectomy: afterwards periods stop for good, and pregnancy is no longer possible.
Q 10What is the median length of the human menstrual cycle?
28 days
28 days: yet cycles anywhere from 21 to 35 days long count as normal.
Q 11Which day is counted as day one of the menstrual cycle?
The first day of bleeding
The first day of bleeding: pregnancies are dated from it too, so at conception a pregnancy already counts as about two weeks along.
Q 12What is the medical term for a girl's first period?
Menarche
Menarche usually comes before a girl ovulates regularly, which is why early periods are often irregular and can take years to settle.
Q 13A surge in which pituitary secretion triggers ovulation?
Luteinizing hormone
Luteinizing hormone: home ovulation predictor kits work by detecting this surge in urine.
Q 21Which condition becomes more likely after menopause, as bone loss speeds up?
Osteoporosis
Osteoporosis: it can weaken bones so much that even a minor fall, which a healthy bone would withstand, causes a fracture.
Q 22The hot flushes of menopause are mainly linked to falling levels of which hormone?
Estrogen
Estrogen: hormone replacement therapy, which supplies it again, can relieve the flushes.
Q 23Which bone is the most sexually dimorphic in the human skeleton, and so most reliable for determining sex from remains?
The pelvis
The pelvis: a woman's is larger and broader, a trade-off between efficient walking and a birth canal wide enough for a baby's head, as the obstetrical dilemma hypothesis proposes.
Q 14After ovulation, the follicle's remains form a temporary progesterone gland called what?
Corpus luteum
Corpus luteum is Latin for 'yellow body'; if no pregnancy begins, it breaks down into a white scar called the corpus albicans.
Q 15What are Braxton Hicks contractions?
Practice contractions
Practice contractions: they're often mistaken for labour, but unlike real labour they don't build up or come closer together.
Q 16When a pregnant woman's waters break, which structure has ruptured?
The amniotic sac
The amniotic sac: if labour doesn't follow soon after it breaks, doctors usually offer to induce labour because of the risk of infection.
Q 17What does IVF stand for?
In vitro fertilisation
In vitro fertilisation: eggs are fertilised in a lab and the embryo placed in the womb, getting round problems such as blocked or damaged fallopian tubes.
Q 18What does the medical term 'amenorrhoea' mean?
Absence of periods
Absence of periods: it is normal in pregnancy and breastfeeding, but can also follow sudden weight loss or too much exercise.
Q 19What happens to a woman's resting body temperature just after ovulation?
It rises slightly
It rises slightly: progesterone released after ovulation lifts it, which is why fertility-awareness methods record temperature every day.
Q 20What does it mean when a baby is breech late in pregnancy?
Bottom or feet first
Bottom or feet first: from about 36 weeks, a doctor may try to turn the baby head down by pushing on the mother's belly, a procedure called ECV.
Q 24Which skin condition, nicknamed the 'mask of pregnancy', causes dark patches on the face?
Melasma
Melasma: sunlight can darken the patches or bring them back after they fade, so protecting the skin from the sun matters.
Q 25What is the most common cause of heavy bleeding just after childbirth?
The uterus failing to contract
The uterus failing to contract: after birth its muscle normally clamps shut the blood vessels where the placenta was attached.
Q 26Which mineral are women with heavy periods most at risk of running low on?
Iron
Iron: blood lost each period carries iron with it, and heavy periods and pregnancy are very common causes of iron deficiency anaemia.
Q 27What is usually the first physical sign of puberty in girls?
Breast budding
Breast budding: it usually begins between 8 and 13, so signs of puberty before 8 can mean early puberty, which a GP can check.
Q 28What is the medical term for the onset of breast development at puberty?
Thelarche
In the two years after it, the uterus, ovaries and follicles all grow; menarche follows later.
Q 29Besides connective tissue, which two tissue types make up the breast?
Adipose and glandular
Adipose and glandular: breasts with more glandular tissue look denser on a mammogram, where tumours can be harder to spot.
Q 30The suspensory bands that support the breast are named after which English surgeon?
Cooper
Cooper: Sir Astley Cooper, who described the ligaments in 1840, had removed a cyst from King George IV's scalp and was made a baronet.
