5 marks~8 minCriterion D
Many people use smartphone apps to track their menstrual cycle and predict ovulation (the release of an egg from the ovary). Most apps assume a regular 28-day cycle, with ovulation on day 14.
a
Identify what data a fertility tracking app collects and state how it uses this data to predict the fertile window — the days when pregnancy is most likely. [2]
b
Explain one reason why an irregular menstrual cycle reduces the accuracy of a fertility tracking app. [1]
c
Describe one limitation of fertility tracking apps other than irregular cycles, and explain how it could lead to an incorrect prediction. [2]

3QuestionIntroduction to Human Reproductive OrgansAssessment Practice
5 marks~8 minCriterion C
The graph below shows levels of two hormones — FSH (follicle-stimulating hormone) and LH (luteinizing hormone) — across a 28-day menstrual cycle. The y-axis shows hormone concentration; the x-axis shows days 1–28.
a
Identify which hormone peaks on day 14. [1]
b
Describe what happens to FSH levels between days 12 and 14, and explain how this relates to the rise in LH over the same period. [2]
c
Compare the roles of FSH and LH in the menstrual cycle, using evidence from the graph to support your answer. [2]

6 marks~9 minCriterion B
A student investigates how uterine lining thickness and progesterone level (a hormone that prepares the uterus for pregnancy) affect implantation success.
Day post-ovulation: 5 / 6 / 7 / 8 / 9
Uterine lining (mm): 6.5 / 7.8 / 8.2 / 9.1 / 7.0
Progesterone level (a.u.): 8 / 12 / 15 / 18 / 9
Pregnancy achieved: No / No / Yes / Yes / No
Day post-ovulation: 5 / 6 / 7 / 8 / 9
Uterine lining (mm): 6.5 / 7.8 / 8.2 / 9.1 / 7.0
Progesterone level (a.u.): 8 / 12 / 15 / 18 / 9
Pregnancy achieved: No / No / Yes / Yes / No
a
Identify the two days on which implantation was successful. [1]
b
Describe the pattern in uterine lining thickness and progesterone level on the days when pregnancy was achieved, compared with the days when it was not. [2]
c
On day 10, the uterine lining is 7.5 mm and progesterone is 11 a.u. Compare these values with the pattern you described and explain whether pregnancy is likely to be achieved. [3]
