Contraception - the options
The combined oral contraceptive pill, which contains
the
hormones oestrogen and progestogen, is very effective
and must be taken daily. Occasionally, bleeding can occur
mid-cycle.
The progestogen-only or 'mini-pill' is another
form of oral
contraception and must also be taken daily. 'Spotting'
or
irregular bleeding can occur.
Hormone injections contain progestogen only and
provide
contraception for 12 weeks, after which time another
injection must be given.
Hormone implants contain progestogen only and are
effective for 5 years; unlike injections, implants can
be
removed at any time. Bleeding can, however, be irregular.
The intrauterine contraceptive device (IUCD) is
inserted
at a clinic under medical supervision. Periods can be
heavy after insertion. The device is usually replaced
after 5 years.
The intrauterine system (IUS) is an intrauterine
contraceptive that contains the hormone levonorgestrel.
In addition to providing contraception, it also helps to
lighten heavy periods.
The diaphragm and cervical cap are inserted before
sexual
intercourse. They should both be used in conjunction with
a spermicide.
Sterilization involves an operation. In a woman,
this
involves closing off the tubes that carry the egg from
the
ovary to the womb. This form of contraception should be
considered permanent.
