Answer:
6. Three hormones are the principle regulators of the male reproductive system: follicle-stimulating hormone (FSH) stimulates spermatogenesis; luteinizing hormone (LH) stimulates the production of testosterone; and testosterone stimulates the development of male secondary sex characteristics and spermatogenesis.
7. Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.
8. Vagina. 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).
9. Vas Deferens: two long, thin tubes that serve as a passageway for sperm and a place for sperm storage. The was deferens are lined with cilia. The contraction of the was deferens along with the action of the cilia help transport the sperm through the vas deferens.
10. Scrotum. The bag of skin that holds and helps to protect the testicles. The testicles make sperm and, to do this, the temperature of the testicles needs to be cooler than the inside of the body. This is why the scrotum is located outside of the body.
