- vagina
- site where sperms aredeposited during sexualintercourse
- cervix
- neck of uterus which widensduring childbirth
- uterus
- structure where fertilisedovum will be implanted in
- where the embryo developsduring pregnancy
- male
- scrotum
- sac that holds the testisoutside the body
- sex glands

- releases fluids that nourishesand protect the sperm
- epididymis
- stores the sperms that are produced

- process whereby a matureovum is released from anovary
Contraceptive Methods
- permanent
- vasectomy
- tie and cut the sperm duct
- temporary
- condom
- fine rubber worn over the penis
- act as a barrier between eggsand sperms
- may be coated withspermicide to kill the sperms
- ligation
- to cut and tie the Fallopian tube
- diaphragm
- a rubber cap inserted into the vagina andplaced over the cervix before sexualintercourse
- acts as a barrier betweeneggs and sperms
- may be used with spermicide
- contraceptive pills
- contains synthetic femalesex hormones
- suppresses the developmentand release of eggs
- intra-uterine device(IUD)
- inserted into the uterus by doctors
- prevent implantation of thefertilised egg in the uterus
STI
- AIDS(acquiredimmunodeficiency syndrome)
- syphilis
- gonorrhea
Fertilization
- the fusion of an ovum and a sperm
