What is Menstrual Cycle & Fertility?
The menstrual cycle is a monthly series of changes a woman's body goes through in preparation for the possibility of pregnancy. It is controlled by four key hormones: FSH, LH, oestrogen, and progesterone. These hormones interact to cause the maturation and release of an egg (ovulation) and the build-up of the uterus lining.
Board notes: Covered by all major boards (AQA, Edexcel, OCR), particularly at the Higher tier. The interaction between the four hormones is a key focus.
Step-by-step explanationWorked examples
Worked example 1: Core method
On day 1 of the cycle, menstruation begins. The pituitary gland releases FSH, causing an egg to mature in a follicle in the ovary. The follicle produces oestrogen, which causes the uterus lining to thicken. Around day 14, a surge in LH triggers ovulation. The empty follicle then produces progesterone to keep the lining thick.
Worked example 2: Exam variation
Now change one detail in the question and keep the same structure: name the Menstrual Cycle & Fertility idea being tested, show the method or evidence, then explain why it answers the command word. This helps GCSE Biology students avoid memorising one surface pattern.
Worked example 3: Mark-scheme check
Finish by checking the answer against marks: one point for the correct Menstrual Cycle & Fertility idea, one for accurate working or evidence, and one for a precise final statement. If any step is vague, rewrite it before moving to timed practice.
Mini lesson for Menstrual Cycle & Fertility
1. Understand the core idea
The menstrual cycle is a monthly series of changes a woman's body goes through in preparation for the possibility of pregnancy. It is controlled by four key hormones: FSH, LH, oestrogen, and progesterone.
Can you explain Menstrual Cycle & Fertility without copying the notes?
2. Turn it into marks
On day 1 of the cycle, menstruation begins. The pituitary gland releases FSH, causing an egg to mature in a follicle in the ovary.
Underline the method, evidence, or command-word move that would earn credit in GCSE Homeostasis & Response.
3. Fix the likely mark leak
Watch for this mistake: Confusing the roles of FSH and LH. FSH (Follicle-Stimulating Hormone) stimulates the egg to mature in the ovary. LH (Luteinising Hormone) triggers the release of the mature egg (ovulation).
Write one correction rule before doing another practice question.

Mini quiz: Menstrual Cycle & Fertility
Three quick checks for revision practice. They are original StudyVector prompts, not official exam-board questions.
Question 1
In one GCSE sentence, explain what Menstrual Cycle & Fertility is testing.
Answer: The menstrual cycle is a monthly series of changes a woman's body goes through in preparation for the possibility of pregnancy. It is controlled by four key hormones: FSH, LH, oestrogen, and progesterone.
Mark focus: Precise definition and topic focus.
Question 2
A Menstrual Cycle & Fertility question uses an unfamiliar context. What should the answer do before adding detail?
Answer: It should name the process, variable, equation, particle model, or evidence being tested, then explain the result using precise scientific vocabulary.
Mark focus: Method selection and command-word control.
Question 3
A student makes this mistake: "Confusing the roles of FSH and LH. FSH (Follicle-Stimulating Hormone) stimulates the egg to mature in the ovary. LH (Luteinising Hormone) triggers the release of the mature egg (ovulation)." What should their next repair task be?
Answer: Do one Menstrual Cycle & Fertility question and review the mistake type.
Mark focus: Error correction and next-step practice.

Core idea
What is the main idea in Menstrual Cycle & Fertility?
The menstrual cycle is a monthly series of changes a woman's body goes through in preparation for the possibility of pregnancy. It is controlled by four key hormones: FSH, LH, oestrogen, and progesterone.
Common mistake
What mistake should you avoid in Menstrual Cycle & Fertility?
Confusing the roles of FSH and LH. FSH (Follicle-Stimulating Hormone) stimulates the egg to mature in the ovary.
Practice
What is one useful practice task for Menstrual Cycle & Fertility?
Answer one Menstrual Cycle & Fertility question and review the mistake type.
Exam board
How should you use board notes for Menstrual Cycle & Fertility?
Covered by all major boards (AQA, Edexcel, OCR), particularly at the Higher tier. The interaction between the four hormones is a key focus.
Common mistakes
- 1Confusing the roles of FSH and LH. FSH (Follicle-Stimulating Hormone) stimulates the egg to mature in the ovary. LH (Luteinising Hormone) triggers the release of the mature egg (ovulation).
- 2Thinking that menstruation (the period) is the main event. The period is just the first phase; the whole cycle is about 28 days long and involves complex hormonal interactions leading up to ovulation.
- 3Forgetting the role of progesterone. Progesterone is crucial for maintaining the lining of the uterus during the second half of the cycle, ready for a fertilised egg to implant.

Frequently asked questions
What are the four hormones of the menstrual cycle?
The four main hormones are Follicle-Stimulating Hormone (FSH), Luteinising Hormone (LH), oestrogen, and progesterone. FSH and LH are produced by the pituitary gland, while oestrogen and progesterone are produced by the ovaries.
How do hormonal contraceptives work?
Hormonal contraceptives, like the combined pill, contain oestrogen and progesterone. These inhibit the production of FSH and LH, preventing an egg from maturing and being released, thus preventing pregnancy.
