Safer
Sex and Contraception -
New
Contraception
What's
New in Contraception:
The
Female Condom:
The
female condom is exactly as its sounds. It is made of polyurethane
that seems like a male condom but it has no latex,
it fits inside the vagina completely covering the walls
of
the vagina and cervix as well as some of the vulva (the outer
areas of the vagina).It is
visible outside the vagina, when inserted correctly.
Put
in before sex, the female condom protects against pregnancy
and infection. Like a male condom, it can only be used
once. The failure rates for pregnancy, are similar to those
of
the
male condom with between 5-15% of women using this
method getting
pregnant each year. It is available for sale,
at Family Planning Victoria as well as some other
sexual health clinics.
But
doesnt it feel strange?
- Up
to 70% of women and their partners like using it
- Because
the polyurethane conducts heat, the female condom can
be
more sensitive than the male condom
- For
HIV positive women the added security of the female condom
(in protecting their partner from infection) means they
can relax and enjoy sex more
- It
does not hurt to insert (although it can take practice!)
- It
can be used hours before intercourse so there are no interruptions
- It
can be used during a womans period
- It
can be used when a male partner cant or wont
use a male condom.
Advantages of
the female condom
- suitable
for men and women who have latex allergies. Non latex,
polyurethane condoms for men are also available in Australia.
These
have the advantage of being stronger and
thinner than latex condoms. They are also safe to use
with
oil based
lubricants, and warm to body temperature,
conducting heat well and are an alternative when latex
allergy is a problem
- possibly
greater protection against sexually transmitted infections,
as it covers some of the vulva
- the
penis can remain inside the vagina after ejaculation
with no fear of failure of the method.
Implanon:
Recent to
Australia (first released in May,2001) Implanon is a small
implant that lasts for 3 years.
Just
4 cms long and 2 mms wide it is inserted by a doctor under
the skin just above the inside of your elbow.
How
Does Implanon Work
Implanon
contains a hormone, a progesterone, which prevents pregnancy
by stopping ovulation. It also affects the mucus produced
by cervix which prevents implantation of a fertilised egg.
Advantages:
- While
it can be felt it cannot be seen
- It
is inserted very simply after a local anaesthetic numbs
the area
- The
procedure takes just a few minutes
- Depending
when in your cycle it is inserted it can be effective immediately
or within 7 days of insertion
- After
removal a womans ovulation, and fertility, returns
to normal within 3 weeks
- It
is almost 100% effective
- Removal
is usually relatively quick and easy.
Disadvantages:
- Irregular
vaginal bleeding
- Acne
- Headaches
- Breast
pain
- Possible
weight gain.
Mirena
Mirena
is a new type of IUD (intrauterine device). Fitted inside
the uterus it remains in pace until removed, releasing a hormone
like progesterone into the uterus.
Advantages:
- Unlike
traditional IUDs Mirena it does not cause heavy bleeding
or vaginal bleeding between periods once it has been in
place for some months
- It
is almost 100% effective
- It
can be used for up to 5 years
- Is
a procedure done by a doctor trained in its insertion,
which in some circumstances may be done under a general
anaesthetic
- Fertility
returns with over 90% of women conceiving within 12 months
after removal.
Disadvantages:
- Headaches
- Breast
pain and tenderness
- Acne
- Mood
changes.
However
only a small percentage report any of these symptoms and when
present these symptoms can decrease after 3 months.
New
Pills on the Market
While
The Pill has been around for decades there have been recent
advances that make The Pill easier, safer and more successful
to use.
The
Pill contains two hormones oestrogen and progesterone.
New contraceptive pills on the market have less oestrogen
than the older types of pill which result in less
- Nausea
- Cyclical
weight loss
- Bloating
- Vaginal
discharge.
The
new lower oestrogen pills are just as effective at preventing
pregnancy and they are particularly useful for women approaching
menopause.
There
are two new forms of oestrogen and progesterone containing
contraception that will come to Australia in the next few
years. They work in a similar fashion to the pill but the
hormones are delivered to the
body in a different way. One method will use a patch on
the
skin
that is changed
weekly. The other method is a rubber-like ring that contains
the hormones. The ring is 5cm in diameter and is placed
inside the vagina. It is left in for three weeks then taken
out for a hormone-free week and withdrawal bleed (period).
Both methods are reportedly as effective as the pill and
possibly less likely to be forgotten. What
about the "mini pill"?
A
new mini-pill or progesterone-only will soon be available
in Australia. Unlike the current mini-pills which have to
be taken at the same time each day with just a 3 hour
leeway,
the new mini-pill can be taken with a 12 hour leeway. This
pill is perfect for women who want to avoid oestrogen.
Emergency
contraception
Emergency
contraception is contraception taken after
unprotected sexual intercourse to prevent pregnancy. Methods
for emergency contraception have greatly improved
in recent years. It is now possible to take this form of
contraception
containing progesterone only. The absence of oestrogen, means
it is much less likely to cause nausea and vomiting, and
other
side effects. It is also more effective than the older form
of emergency contraception, which contained both oestrogen
and progesterone. The newest forms prevent 88% of pregnancies,
which would normally have occurred, as opposed to a 75%
with
the older form containing oestrogen and progesterone.
It is best to take it as soon as possible but it can be
taken up to 120 hours after unprotected sex.
The
new progesterone only emergency contraception is called postinor-2
or Levonelle-2 and is available over the counter without a
prescription from pharmacies.
Permanent
methods
If
you are sure that you want to be permanently sterile,
there
is a new method of contraception called Essure pbc available
to Australian women. The method involves the blocking of
the
fallopian
tubes using
a micro-coil which is inserted via the vagina. Unlike traditional
sterilisation the insertion is via the vagina rather than
through an incision in the abdomen, which means a faster
recovery time. The procedure is only done by a few specially
trained
gynaecologists. Ask your doctor or Family Planning Victoria
about the procedure.
