Fertility Info
An Overview
 In
simple words infertility is defined as the inability to conceive. And
this is the reason, it requires thorough diagnosis of both the partners.
Once, this malady is diagnosed, there is every possibility that it could
be treated successfully.
However, there are other factors as well like age, general health etc.,
that may affect the success of treatment.
At the same time, with technological advancements in the field of
surgery and/or assisted reproductive technologies (ART), such as in
vitro fertilization (IVF), majority of infertility treatments are successful.
women Infertility Treatment
The common cause of Infertility in women is disruption of ovulation
symphony by disturbances in menstrual cycle. Instead of a regular cycle,
the women suffering from infertility undergo irregular cycles. In the
wake of this, menstrual history is considered to be the first instance
of infertility, which one should seriously take care of and immediately
consult the doctor.
The Menstrual Pattern is the simplest screening test to guide medical
investigations.
Menstrual Patterns
- The regular menstrual period: In this category, the periods are
regular from month to month, beginning like clockwork every
twenty-five days or every thirty-five days. The consistently
irregular menstrual cycle, where one month you begin menstruating
after twenty-five days, the next month after thirty-four, and the
next in thirty, may indicate that you have fertility problem.
- Irregular menstrual periods or Amenorrhea for six or more
months: Irregular periods aren't unusual, they affect about 30% of
women in their reproductive years. The woman's menstrual periods
occur infrequently and at unpredictable intervals. Even in some of
the cases, the menstruation at a period of time, may suddenly stop
altogether.
- Nonexistence of the menstrual period: If a women does not have
menstruate even after the age of 16 years, which is considered to be
the maximum limit to start menstruating, it is considered to be a
serious condition. The cause of such conditions may include genetic
abnormalities, congenitally deformed reproductive organs, delayed
puberty, or a pituitary malfunction.
What is Ovulation?
Ovulation is the process in the menstrual cycle by
which a mature ovarian follicle ruptures and discharges an ovum (also
known as an oocyte, female gamete, or casually, an egg) that
participates in reproduction. The entire process of ovulation is
controlled by the hypothalamus of the brain and through the release of
hormones secreted in the anterior lobe of the pituitary gland,
Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH). A spike
in the amount of FSH triggers ovulation and LH is released from the
pituitary gland.
Causes of Infertility
There are various conditions that may cause
infertility in the women. These conditions include the following:
Endometriosis:
It is a common medical condition in which the endometrial tissue, the
tissue that normally lines the uterus, grows outside the uterus and
attaches to other organs in the abdominal cavity such as the ovaries and
fallopian tubes. Endometriosis is a progressive disease that tends to
get worse over time and can reoccur after treatment.
The most common symptom of endometriosis is pelvic pain. The pain often
correlates to the menstrual cycle, but a woman with endometriosis may
also experience pain that doesnt correlate to her cycle. The other
symptoms include abnormal menstrual bleeding and pain during or after
sexual intercourse. Endometriosis can also cause scar tissue and
adhesions to develop, that can distort a womans internal anatomy.
A laparoscopy, an outpatient surgical procedure, is necessary to
confirm a diagnosis of endometriosis after a medical history review and
pelvic exam. After the diagnosis, our physician will classify your
condition as stage 1 (minimal), stage 2 (mild), stage 3 (moderate) or
stage 4 (extensive). Based on the stage of the Endometriosis, the
physician may decide the best treatment plan.
Polycystic ovary syndrome (PCOS)
Polycystic ovary syndrome (PCOS) is the most common endocrine
abnormality that affects six to ten percent of women, who are in the
reproductive age group. PCOS is a leading cause of infertility and also
affects the woman's cardiovascular health. The causes of PCOS are
unknown. Researchers believe that the causes of PCOS may be insulin
resistance and an imbalance of female hormones (estrogens and
progestins, those important for the menstrual cycle) contribute to the
development of this condition.
The symptoms of the disorder include acne, difficulty becoming pregnant
(infertility), irregular menstrual periods, obesity, skin discolorations
and unwanted hair growth or loss.
New medical researches have revealed different methods of treatment
including insulin-reducing ovulation medication (clomiphene, glucophage,
metformin), dietary changes (low glycemic diet) and surgery (ovarian
drilling). Women who undergo treatment for PCOS, but are still unable to
conceive naturally, often turn to assisted reproductive technologies
such as IVF.
Tubal diseases
One of the more common causes of infertility is - blocked or damaged
fallopian tubes. The fallopian tubes are necessary for picking up the
egg, released from the ovary. It is in the inside of the fallopian tube
that natural fertilization occurs. Scar tissue resulting from
endometriosis or abdominal or gynecological surgery, such as bowel
surgery, cesarean section or a ruptured appendix, can block an egg from
entering or traveling down the fallopian tube to meet the sperm,
preventing fertilization.
Such condition may cause infections including chlamydia, can damage the
cilia, the tiny hairs lining the fallopian tubes that help transport the
egg, often preventing the sperm and egg from meeting. One result of
damaged cilia is an ectopic pregnancy, which occurs when an egg is
fertilized but, due to the damaged cilia, it is unable to travel to the
uterus, growing instead in the wall of the fallopian tube. This
condition can result in rupture, internal bleeding and further tubal
damage.
The physician reviews the complete history and does a complete pelvic
exam to diagnose the tubal disorder. For the confirmatory diagnosis,
additional tests such as hysterosalpingogram and laparoscopy are
required and the exact course of treatment is decided on the basis of
the condition.
Unexplained
In about one third of the couples despite an extensive battery of
tests, we are unable to find the cause. These couples are termed to be
suffering from unexplained infertility. Perhaps there is a
problem with sperm egg interaction. These couples may benefit from
superovulation and IUI or IVF.
Men Infertility Treatment
In men, infertility generally is caused by a lack of sperm in the semen
(azoospermia), deformed or structurally abnormal sperm, sperm that lack
the ability to reach and fertilize a female egg (immotile sperm).
Genetic, infection, testicular trauma, hormonal imbalance or exposure to
radiation and certain medications are all causes of sperm production
disorders.
Infertility normally occurs when there is a low sperm count, or
problems with the motility (movement) or morphology (appearance or
shape) of the sperm. Sperms that have poor motility, are often not able
to reach the egg and therefore, fertilization does not occur. Abnormal
sperms are sometimes unable to penetrate and fertilize the egg. Sperm
DNA damage may interfere with conception as well as lead to a greater
risk of miscarriage.
Any structural or anatomical problem that may block the path of sperm
can cause infertility, by preventing fertilization to occur. Infertility
related to structural and anatomical problems in the male anatomy may be
caused by scar tissue, varicose veins or infection or, in some cases,
the problems exist from birth.
In few cases, the immune system of the men develop antibodies that may
attack the sperm and destroy their ability to fertilize the egg.
Antibodies bind to specific parts of the sperm, such as the head or tail
and, depending on the site of attachment and interfere with the movement
of the sperm.
Getting Prepared for Pregnancy
 Since,
female fertility declines with age, it is always advisable to take
certain precaution if couples who are planning to become pregnant or
conceive. Some of the major precautions are as follows:
- Women who are planning for pregnancy should avoid liquor and
under no circumstances advised to take more than one or two units of
alcohol, once or twice per week.
- Avoid smoking as it reduces fertility.
- Women with body mass index (Wt (kg)/Ht (m2) of more than 29
normally take longer to conceive.
- Women who have a body mass index of more than 29 and who are not
ovulating - losing weight is likely to increase their chance of
conception.
- Women with a body mass index of less than 19, having irregular
menstruation or not menstruating at all are advised to increase
their body weight as it improves the chances of conception.
- Healthy diet (low carbohydrates, high proteins and minerals) and
lifestyle would aid you in your efforts to become pregnant.
- Drinking plenty of water ( upto 2-3 litres) is good for your
health .
- Before attempting pregnancy , it is advisable to ensure that you
have antibodies against Rubella, your blood sugar and thyroid levels
are under control and that you are not a carrier of Thallasemia.
Success Rate
The age of the woman has a major impact on the IVF
success rates. If the age of the woman is less than 35 years , the
success rate is higher and it falls dramatically after 40 years. Studies
have shown that for women under 35, the pregnancy rate is commonly
higher and is approximately 43% per cycle, whereas, the rate drastically
falls for women over 40.
Other factors that determine success rate include eggs and sperm
quality, infertility duration, and overall condition of the endometrium
and the ease of embryo transfer.
Complications
- The major complication is the risk of multiple births due to the
multiple embryos transferring practice. It may lead to pregnancy
loss, obstetrical complications, prematurity, neonatal morbidity
along with the potential for long term damage.
- Spontaneous splitting of embryos in the womb after transfer, may
also occur which leads to identical twins.
- Another risk of ovarian stimulation is the development of
ovarian hyperstimulation syndrome.
