2. Humans have body parts called organs
that enable us to reproduce. These organs
have coordinated functions that form a
body system called the reproductive
system. In this lesson, you will learn about
structures of the reproductive organs and
their specific functions.

4. Male Reproductive…
The male reproductive system is made up of
different organs and glands.
Some of these parts are involved in the
production of sperm cells, while some are
involved in the delivery of the sperm cells to the
female reproductive system.
The ability to produce sperm cells does not
necessarily mean the ability to produce a new
individual. The number and the quality of sperm
cells also determine the capability of sperm cells
to unite with female egg cells.
5. Factors that affect sperm number and
quality:
• Smoking
• Excessive alcohol intake
• Emotional stress
• Substance abuse
• Malnutrition
• Heredity
• Exposure to toxins and chemicals
6. CHANGES DURING PUBERTY
• Your body changes in many ways as you grow
and mature. Have you noticed any changes in
your body? Some of these changes happen
because you are entering a new stage in life –
puberty.
7. • Puberty is a stage of life. Rapid physical
growth characterizes this stage. Different
substances called hormones trigger these
changes in your body. You start to mature
sexually. At puberty, your reproductive
organs develop and are able to function for
reproduction.
• Teenagers are usually prone to body odor
and too much oil secretion, especially on
the face. Many products in the market
today claim to solve these problems.
8. • During puberty, the pituitary gland
secretes natural chemical substances
called hormones.
– The pituitary gland controls the functions of
several body organs through the hormones it
secretes. These hormones are responsible for
physical changes in adolescents. One of these
hormones is the growth hormone.
•Growth hormones stimulate growth and cell
reproduction.
9. • You also experience emotional changes
during puberty. Upon reaching
adolescence, you become more excited
and curious to discover new things.
