Explanation

The corpus luteum secretes the hormone progesterone. Progesterone prepares the uterus for a fertilized egg to implant.

Multiple choice

  1. FSH and LH are released from the brain.

  2. The estrogen level falls.

B Correct answer
Explanation

As estrogen levels rise, like a switch, it turns off the production of follicle-stimulating hormone. This careful balance of hormones allows the body to limit the number of follicles that mature.

Multiple choice

The menopause transition years are termed as

  1. Menopause

  2. Perimenopause

  3. Premenopause

  4. Postmenopause

B Correct answer
Explanation

Perimenopause is the term used to describe the menopause transition years. In women who have a uterus, perimenopause describes the years before and after the final period (although it is only possible to determine in retrospect which episode of flow was indeed the final period).

Multiple choice

The ovulatory phase, or ovulation, starts about 14 days after the follicular phase starts. Which among the following statements can be excluded from this phase?

  1. Estrogen level rises.

  2. Egg releases from the follicle

  3. Thickness of mucus from cervix increases

  4. One follicle in one ovary becomes dominant and continues to mature.

D Correct answer
Explanation

As the follicular phase progresses, one follicle in one ovary becomes dominant and continues to mature. This dominant follicle suppresses all of the other follicles in the group. As a result, they stop growing and die. The dominant follicle continues to produce estrogen.

Multiple choice

The absence of menstrual periods is known as

  1. Menorrhagia

  2. Dysmenorrhoea

  3. Endometriosis

  4. Amenorrhoea

D Correct answer
Explanation

Amenorrhoea simply means an absence of your periods. Doctors usually classify amenorrhoea into primary or secondary amenorrhoea. Girls who haven't started their periods by the time they're 16 years old or 3 years after they've shown the first signs of puberty have primary amenorrhea, which is usually caused by a genetic abnormality, a hormone imbalance, or a structural problem.

Multiple choice

  1. It plays a major part in women's fertility problems.

  2. Symptoms include pain before and during the period.

  3. It is not suppressed during pregnancy.

  4. It is more likely in women with family history of endometriosis.

Having a baby does not cure endometriosis. It is suppressed during pregnancy, but the symptoms may recur.

Multiple choice

During which phase of menstruation cycle is the egg released?

  1. Menses

  2. Follicular phase

  3. Ovulation phase

  4. Luteal phase

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A surge of luteinising hormone occurs roughly just before day 14 in a 28-day cycle. This surge stimulates the mature follicle in one of the ovaries to release its egg (ovulation) 16 to 32 hours later. The other follicles over-ripen and break down. Oestrogen also peaks during this surge. Some women can feel a pain on one side of the abdomen around the time the egg is released.
