Worked practice questions

Fertilisation in humans typically occurs in the

  1. uterus
  2. vagina
  3. fallopian tube (oviduct)
  4. ovary
Show answer and solution

Correct answer: C. fallopian tube (oviduct)

Sperm meet the egg in the ampulla of the fallopian tube, soon after ovulation. The resulting zygote then travels down to the uterus, where it implants in the lining.

Oogenesis in humans begins

  1. at puberty
  2. during the menstrual cycle each month
  3. before birth, during fetal life
  4. after ovulation
Show answer and solution

Correct answer: C. before birth, during fetal life

Primary oocytes form during fetal development (~20 weeks gestation). They remain arrested in prophase I until puberty, then resume meiosis one at a time at each ovulation. Most degenerate without being released.

Ovulation in a typical 28-day human menstrual cycle occurs around day

  1. day 1
  2. day 7
  3. day 14
  4. day 28
Show answer and solution

Correct answer: C. day 14

Ovulation around day 14 — triggered by a surge of LH. The egg is then viable for ~24 hours sperm can survive ~5 days, so fertile window is ~6 days around ovulation.
