2. After going through this module,
you are expected to:
1. Describe the feedback
mechanisms involved in
regulating processes in
the female reproductive
system (e.g., menstrual
cycle)
• 2. Relate the menstrual
cycle of the female to the
ability to get pregnant or
reproduce; and
• 3. Spread awareness
within the family
about family planning
and the national crisis
on teenage pregnancy.
4. How do you think
women's bodies change
from childhood to
adolescence?
5. • As we grow older, our body changes in so
many ways. Many changes occur during
our adolescence (age 10-19). The changes
in males are very different from those in
females.
• One of these differences is that girls
menstruate while boys don’t.
6.
7. The sex hormones cause these
changes, including the events
that happen during the
menstrual cycle and those
leading to reproduction
10. Menstruation is a sign that a girl
is capable of producing offspring.
The menstrual cycle is a series of
changes during which an egg
matures, and the uterus is
prepared for possible pregnancy.
11. The menstrual cycle is
influenced by the endocrine
system through the
complex interaction of the
hypothalamus, pituitary
and gonads (reproductive
or sex organs, specifically
the ovaries and testes).

15. The menstrual cycle describes recurring changes
that occur within the female reproductive system
to make pregnancy possible.
Each menstrual cycle lasts roughly one month

before ending with menopause

22. There are two key groups of hormones
which control and coordinate the menstrual
cycle:
1. Pituitary hormones (FSH and
LH) are released from the
anterior pituitary gland and act
on the ovaries to develop
follicles
2. Ovarian hormones (estrogen
and progesterone) are released
from the ovaries and act on the
uterus to prepare for pregnancy
