Answers:
1. Testosterone is important in the first stages of developing the male reproductive organs in a foetus. It also causes the development of male characteristics such as growth of facial hair, deepening of the voice and the growth spurt that takes place during puberty.
2. The reproductive system is responsible for producing offspring. The kidneys are responsible for removing waste.
3. The vagina is the passageway through which fluid passes out of the body during menstrual periods . It is also called the birth canal . The vagina connects the cervix (the opening of the womb, or uterus ) and the vulva (the external genitalia).
4. The ovaries produce eggs and hormones. Fallopian tubes: These are narrow tubes that are attached to the upper part of the uterus and serve as pathways for the ova (egg cells) to travel from the ovaries to the uterus. Fertilization of an egg by a sperm normally occurs in the fallopian tubes.
5. When the male ejaculates (when semen leaves the penis), a small amount of semen is deposited into the vagina. Millions of sperm are in this small amount of semen, and they "swim" up from the vagina through the cervix and uterus to meet the egg in the fallopian tube. It takes only one sperm to fertilize the egg.
6. But exceptions are common. Many men with low sperm counts or abnormal semen are still fertile. And about 15% of infertile men have normal semen and plenty of normal sperm. Surprisingly, the complete absence of sperm in the semen (a condition known as azoospermia), can be a good thing.
7. A woman's ovulation cycles can vary, so it's statistically possible you could become pregnant while on your period. While pregnancy is less likely in the earlier days of your period, the chances increase in the later days.
