and sperms
- may be coated with
spermicide to kill the sperms
- female
- permanent
- ligation
- to cut and tie the Fallopian tube
- temporary

- a rubber cap inserted into the vagina and
placed over the cervix before sexual
intercourse
- acts as a barrier between
eggs and sperms
- may be used with spermicide
- contraceptive pills
- contains synthetic female
sex hormones

and release of eggs
- intra-uterine device(IUD)
- inserted into the uterus by doctors

shed with the help of muscular contractions
of the uterus
- contractions causes cramps
- thickening of uterine lining
- to prepare for
implantation,lining thickens and
become spongy
- becomes full of capillaries
- ovulation(days 14-16)
- considered most fertile period
- process whereby a mature
ovum is released from an
ovary
