Clomid
is an ovulation medication.
Not
all women with fertility problems should take Clomid.
Your doctor should screen you to see if Clomid is
recommended. Couples that have been trying to conceive
and have not gotten pregnant could have any number
of problems. Proper testing and evaluation by a doctor
is necessary to determine what is the best course
of action for you. If you are not ovulating, ovulating
irregularly, or have irregular periods Clomid may
be recommended for you.
Normal
Ovulation
During
the first half of a normal menstrual cycle, follicles
in your ovaries begin to mature and enlarge. Each
of these follicles contains an egg. These follicles
nurture the growing egg. As they mature, they produce
estrogen. Estrogen levels are low in the beginning
of your cycle.
Your
body communicates with hormones. Low estrogen levels
tell your body to produce GnRH (gonadotropin releasing
hormone). GnRH is a hormone produced in the pituitary
gland that stimulates the production of FSH and LH.
FSH, which stands for follicle stimulating hormone,
does exactly what it sounds like, it stimulates the
follicles to grow and mature. As they grow and ripen
they produce more estrogen. This rise in estrogen
triggers a release of LH, also known as an LH surge.
When LH levels surge, it signals the mature egg to
be released from the follicle. Ovulation occurs within
12-24 hours after the LH surge.
How
does Clomid work?
Clomid
works by blocking estrogen receptors in the
brain.
Hormones
are your body’s way of communicating.
Hormones attach to hormone receptors to communicate.
Think of it like a puzzle piece that fits together.
When estrogen attaches to its receptor cell
in the hypothalamus it communicates and lets
the brain know that estrogen levels are increasing.
Clomid has a similar structure to estrogen.
Clomid attaches to the receptor cell in the
hypothalamus, which keeps the estrogen from
attaching. Because the Clomid is blocking the
receptors, they don’t get the signal from
the estrogen and this essentially tricks your
body into thinking there is not enough estrogen.
Your body tries to kick up the production of
estrogen by producing more GnRH. GnRH is what
causes the release of FSH and LH. And FSH is
what makes the follicles ripen and produce more
estrogen. If the Clomid does what it is supposed
to, your body will be tricked into producing
more FSH and LH, which will hopefully cause
your body to ovulate.
How
do you know if you need Clomid?
Your
doctor will want to see if you are ovulating
normally. If you have an irregular cycle there
is a good chance you are not ovulating normally.
It is a good idea to keep a record of your cycle
if you are trying to conceive. Keeping a bbt
chart of your
cycles will help your doctor determine whether
or not you are ovulating. You may also want
to use a fertility monitor. Fertility monitors,
such as the Clear Blue Easy monitor, are a great
way to determine if and when you are ovulating.
If you are not ovulating or ovulating irregularly
your doctor may order tests and/or prescribe
Clomid.
Your
doctor will probably start you on a low dosage
of Clomid. Standard starting dosage is around
50 mg. Clomid is generally given on days 3-7
or days 5-9 of your cycle. (Three days after
your period starts or five days after your period
starts) If you are not having a regular period,
your doctor may prescribe medication to induce
a period. He will give you a pregnancy test
before he does this. Clomid is taken orally
and should be taken the same time each day for
five days. If ovulation occurs it is generally
a week or so after taking your last dosage of
Clomid. Your doctor will probably have you keep
a bbt
chart or use
an ovulation prediction kit to
see if you have ovulated. He may also perform
an ultrasound to check the number and size of
the developing follicles. |
Clomid
Side Effects
Because
Clomid works to block estrogen receptors, it not only
blocks the receptors in the hypothalamus, but it also
blocks the receptors in the cervix. Estrogen helps
encourages the production of fertile cervical mucous.
With the receptor cells being blocked your body may
produce dry or hostile cervical mucous which is not
the best environment for transporting sperm into the
uterus. Your doctor may prescribe a low dose of estrogen
to help with this. Other side effects of Clomid are
hot flashes, mood swings, headaches, visual disturbances,
and hyperstimulation syndrome. Tylenol may help to
relieve some of these symptoms. There is also a ten
percent chance of having twins
while taking Clomid.
How
long should I take Clomid?
Your
doctor will start off with a low dosage of Clomid
and may increase your dosage if ovulation does not
occur. Most authorities recommend taking Clomid for
no more than six cycles. If pregnancy does not occur
in this time frame, your doctor will probably look
into another treatment for you.
How
successful is Clomid?
According
to the American Society for Reproductive Medicine,
up to 45 percent of women receiving Clomid will become
pregnant after six cycles.
