Female infertility ? CHILDLES MOTHER
Female infertility, male infertility or
a combination of the two affects millions of couples in the United States. An
estimated 10 to 18 percent of couples have trouble getting pregnant or having a
successful delivery.
Infertility results from female factors about one-third of the time
and male factors about one-third of the time. The cause is either unknown or a
combination of male and female factors in the remaining cases.
Female infertility causes can be difficult to diagnose. There are
many available treatments, which will depend on the cause of infertility. Many
infertile couples will go on to conceive a child without treatment. After
trying to get pregnant for two years, about 95 percent of couples successfully
conceive.
Symptoms
The main symptom of infertility is the inability to get pregnant. A
menstrual cycle that's too long (35 days or more), too short (less than 21
days), irregular or absent can mean that you're not ovulating. There may be no
other outward signs or symptoms.
When to see a doctor
When to seek help sometimes depends on your age:
·
Up to age 35, most doctors recommend trying to
get pregnant for at least a year before testing or treatment.
·
If you're between 35 and 40, discuss your concerns with your
doctor after six months of trying.
·
If you're older than 40, your doctor may want to begin
testing or treatment right away.
·
Your doctor may also want to begin
testing or treatment right away if you or your partner has known fertility
problems, or if you have a history of irregular or painful periods, pelvic
inflammatory disease, repeated miscarriages, prior cancer treatment, or
endometriosis. You need to ovulate. To get pregnant, your ovaries must produce and release an
egg, a process known as ovulation. Your doctor can help evaluate your menstrual
cycles and confirm ovulation.
·
Your partner needs sperm. For most couples, this isn't a
problem unless your partner has a history of illness or surgery. Your doctor
can run some simple tests to evaluate the health of your partner's sperm.
·
You need to have regular intercourse. You need to have regular sexual
intercourse during your fertile time. Your doctor can help you better
understand when you're most fertile.
·
You need to have open fallopian tubes
and a normal uterus. The egg and sperm meet in the fallopian tubes, and the embryo
needs a healthy uterus in which to grow.
For pregnancy to occur, every step of
the human reproduction process has to happen correctly. The steps in this
process are:
·
One of the two ovaries releases a mature egg.
·
The egg is picked up by the fallopian tube.
·
Sperm swim up the cervix, through the uterus and into the fallopian
tube to reach the egg for fertilization.
·
The fertilized egg travels down the fallopian tube to the uterus.
·
The fertilized egg implants and grows in the uterus.
In women, a number of factors can
disrupt this process at any step. Female infertility is caused by one or more
of the factors below.
Ovulation disorders
Ovulation disorders, meaning you ovulate infrequently or not at
all, account for infertility in about 1 in 4 infertile couples. Problems with
the regulation of reproductive hormones by the hypothalamus or the pituitary
gland, or problems in the ovary, can cause ovulation disorders.
·
Polycystic ovary syndrome (PCOS). PCOS causes
a hormone imbalance, which affects ovulation. PCOS is
associated with insulin resistance and obesity, abnormal hair growth on the
face or body, and acne. It's the most common cause of female infertility.
·
Hypothalamic dysfunction. Two hormones produced by the
pituitary gland are responsible for stimulating ovulation each month — (FSH)
and luteinizing hormone (LH).
Excess physical or emotional stress, a very high or very low body weight, or a
recent substantial weight gain or loss can disrupt production of these hormones
and affect ovulation. Irregular or absent periods are the most common signs.
·
Premature ovarian failure. Also called primary ovarian
insufficiency, this disorder is usually caused by an autoimmune response or by
premature loss of eggs from your ovary (possibly from genetics or
chemotherapy). The ovary no longer produces eggs, and it lowers estrogen
production in women under the age of 40.
·
Too much prolactin. The pituitary gland may cause
excess production of prolactin (hyperprolactinemia), which reduces estrogen
production and may cause infertility. Usually related to a pituitary gland
problem, this can also be caused by medications you're taking for another
disease.
Damage to fallopian tubes (tubal infertility)
Damaged or blocked fallopian tubes keep sperm from getting to the
egg or block the passage of the fertilized egg into the uterus. Causes of
fallopian tube damage or blockage can include:
·
Pelvic inflammatory disease, an
infection of the uterus and fallopian tubes due to chlamydia, gonorrhea or
other sexually transmitted infections
·
Previous surgery in the abdomen or
pelvis, including surgery for ectopic pregnancy, in which a fertilized egg
implants and develops in a fallopian tube instead of the uterus
·
Pelvic tuberculosis, a major cause of
tubal infertility worldwide, although uncommon in the United States
Endometriosis
Endometriosis occurs when tissue that normally grows in the uterus
implants and grows in other locations. This extra tissue growth — and the
surgical removal of it — can cause scarring, which may block fallopian tubes
and keep an egg and sperm from uniting.
Endometriosis can also affect the lining of the uterus, disrupting
implantation of the fertilized egg. The condition also seems to affect
fertility in less-direct ways, such as damage to the sperm or egg.
Uterine or cervical causes
Several uterine or cervical causes can impact fertility by
interfering with implantation or increasing the likelihood of a miscarriage:
·
Benign polyps or tumors (fibroids or
myomas) are common in the uterus. Some can block fallopian tubes or interfere
with implantation, affecting fertility. However, many women who have fibroids
or polyps do become pregnant.
·
Endometriosis scarring or inflammation
within the uterus can disrupt implantation.
·
Uterine abnormalities present from
birth, such as an abnormally shaped uterus, can cause problems becoming or
remaining pregnant.
·
Cervical stenosis, a narrowing of the
cervix, can be caused by an inherited malformation or damage to the cervix.
·
Sometimes the cervix can't produce the
best type of mucus to allow the sperm to travel through the cervix into the
uterus.
Unexplained infertility
Sometimes, the cause of infertility is never found. A combination
of several minor factors in both partners could cause unexplained fertility
problems. Although it's frustrating to get no specific answer, this problem may
correct itself with time. But, you shouldn't delay treatment for infertility.
Risk factors
Certain factors may put you at higher risk of infertility,
including:
·
Age. The quality and quantity of a
woman's eggs begin to decline with increasing age. In the mid-30s, the rate of
follicle loss speeds, resulting in fewer and poorer quality eggs. This makes
conception more difficult, and increases the risk of miscarriage.
·
Smoking. Besides damaging your cervix and
fallopian tubes, smoking increases your risk of miscarriage and ectopic
pregnancy. It's also thought to age your ovaries and deplete your eggs
prematurely. Stop smoking before beginning fertility treatment.
·
Weight. Being overweight or significantly
underweight may affect normal ovulation. Getting to a healthy body mass index (BMI)
may increase the frequency of ovulation and likelihood of pregnancy.
·
Sexual history. Sexually transmitted infections
such as chlamydia and gonorrhea can damage the fallopian tubes. Having
unprotected intercourse with multiple partners increases your risk of a
sexually transmitted infection that may cause fertility problems later.
·
Alcohol. Stick to moderate alcohol
consumption of no more than one alcoholic drink per day.
