Contraception
The process of preventing sperm cells from fertilizing an ovum
Conception
The moment a single sperm cell penetrates the wall of an ovum and the sperm’s and ovum’s DNA fuse together
Pregnancy
The period of growth of the embryo and fetus in the uterus
Selective abstinence
Choosing to engage in or avoids certain behaviors on the basis of their risks of STIs or pregnancy
celibacy
Choosing to forego all sexual activity
Outercourse
A form of abstinence in which a couple chooses to engage only in sexual behaviors that are unlikely to result in pregnancy or infection and to avoid all others, such as vaginal or anal intercourse and oral sex
Male condom
A thin sheath of latex (rubber) polyurethane (plastic) or animal tissue that is placed over an erect penis prior to and during intercourse
Female condom
A tube or pouch of thin polyurethane with a flexible ring at each end
One end is sewed and the other is open
The condom is inserted into the vagina to protect against pregnancy and the transmission of STIs
Withdrawal method
Removing the penis from the vagina prior to ejaculation— a usually unreliable method of contraception
Also called coitus interruptus and pulling out
Oral contraceptives
Tablets containing female hormones that are ingested every day
They constitute the most popular reversible contraception method used by women in the USA
Birth control pills
Combination pill
An oral contraceptive containing a combination of estrogen and progestin
Minipill
An oral contraceptive containing progestin only
Amenorrhea
Cessation of a woman’s period
Depo-Provera
A hormonal contraceptive in the form of an injection that provides 90 days of protection from conception
Contraceptive patch
A stick-on patch that delivers a precise dose of two hormones into a woman’s body through the skin, preventing ovulation
Contraceptive ring
A colorless, flexible, transparent silicone ring about 2 inches in diameter that is inserted into the vagina and releases a continuous, low dose of estrogen- and progestin- like hormones into the bloodstream
Emergency contraception (EC)
Hormonal contraceptive that helps prevent pregnancy after an unprotected act of intercourse; also know as the “morning-after” pill
Barrier method
Any contraceptive method that protects against pregnancy by preventing live sperm from entering the woman’s reproductive tract
Diaphragm
A flexible ring of latex or silicone inserted into the vagina that impedes conceptions by preventing sperm from getting past the cervix
Cervical cap
A device similar in function to the diaphragm that fits more snugly over the cervix
Spermicide
Any substance containing a chemical (most commonly minoxidil-9) that kills sperm cells, thereby preventing them from fertilizing an egg
Fertility awareness
A method of contraception based on ovulation prediction and the viability of sperm
Intercourse is timed to avoid fertile days or a barrier method is used during those days
Standard days method
A fertility awareness technique for tracking fertile and infertile days during a woman’s menstrual cycle
Two day method
A fertility awareness technique that relies on careful observation of secretions from the cervix to predict ovulation
