ENDOCRINE SYSTEM - One of the major regulatory systems of the body.
It regulates the "slower" processes such as growth and reproduction,
while the nervous system regulates the "faster" processes such as
heartbeats and muscle movements. The endocrine system works by
secreting special "messenger chemicals" called hormones. The
hypothalamus area of the brain instructs the pituitary gland to
secrete hormones that control many other glands. These glands in
turn regulate critical functions such as metabolism and
reproduction. Because the endocrine system regulates reproductive
processes it is important in many aspects of fertility.
Endocrinology is the study of the endocrine system. An endocrine
specialist is called an endocrinologist, and a doctor who
specializes in the reproductive aspects of the endocrine system is
known as a reproductive endocrinologist. See a fertility specialist
now

development of secondary sexual characteristics. Estrogen is
produced mainly by the ovaries from the onset of puberty until
menopause.

These drugs are used as follows:
HMG Human Menopausal Gonadotropins (Pergonal, Repronex) Equal parts
of the naturally occuring hormones FSH and LH. Used for ovarian
stimulation and multiple follicular development prior to IVF
treatment.
FSH Follicle Stimulating Hormones (Follistim, Gonal-F, Bravelle) Has
essentialy the same function as the HMG's-they are used for ovarian
stimulation and multi-follicular development. They contain FSH only
and virtually no LH. Follistim and Gonal -F are manufactured using
recombinant DNA technology, Bravelle is a human derived FSH.
HCG Human Chorionic Gonadotropin (Novarel, Pregnyl, Ovidrel)
Sometimes called the "pregnancy hormone" as this is the hormone
detected by home pregnacy tests. It is produced by the developing
embryo and eventually the placenta. In the manufactured form it is
used to cause ovulation in insemination cycles and is given for
final maturation of oocytes (eggs) prior to IVF.
GnRH Gonadotropin Releasing Hormone (Antagon, Cetrotide, Lupron)
Used in fertility treatment to prevent premature ovulation during
ovarian stimulation prior to IVF. See a fertility specialist now
FERTILITY SPECIALIST - See Reproductive Endocrinologist. See a

FIBROIDS (UTERINE FIBROIDS, MYOMAS) - A non-cancerous tumor found
within the wall of the uterus. Fibroids can be a cause of
infertility. Fibroids are the most common benign tumors in women and
it is estimated that 40% of all women over the age of 35 have
fibroids. They can range in size from as small as a pea to as large
as a grapefruit. Many women have no symptoms, but some women have
symptoms that include: heavy bleeding, pelvic pain, anemia, frequent
urination, difficult or painful bowel movements, swollen or
distended abdomen and infertility. Fibroids can be diagnosed by
pelvic exam, vaginal ultasound and hysteroscopy. The treatment of
fibroids depends upon their type and exact location in the uterine
cavity. Many fibroids do not require treatment, but some must be
removed by a surgical procedure, called myomectomy. A more recent
treatment (Uterine Artery Embolization) does not remove the
fibroids, but causes them to shrink by restricting the blood flow to
the fibroid. See a fertility specialist now

procedure used to determine whether the fallopian tubes are open and
capable of functioning properly. The physician injects dye into the
uterus through the cervix. The dye passes through the tubes if they
are open. An HSG can also reveal information such as the
configuration of the uterus, irregularities, and the presence of

LEUPROLIDE ACETATE - See Lupron.
LH - See Luteinizing Hormone.
LH SURGE - A spontaneous release of large amounts of luteinizing
hormone (LH) during a woman's menstrual cycle. This normally results
in the release of a mature egg from a follicle (ovulation).
LUPRON - A brand name for Leuprolide Acetate. The brand is owned and
manufactured by Abbott Labs. A hormonal medication that can create a
pseudo menopause. A chemical similar to GnRH, it first stimulates
the female hormones, then suppresses a woman's secretion of FSH and
LH. Lupron tends to increase the number of follicles, oocytes
(eggs), and embryos during a cycle, decreasing the risk of a
cancelled cycle.
LUPRON "DOWN REGULATION" - A treatment with Lupron that takes
advantage of the suppression of natural hormone (LH and FSH)
secretions. Used before injection of hMG to stimulate follicular
development.
LUPRON "FLARE" - A treatment with Lupron that takes advantage of the
initial rise or "flare" of the woman's LH and FSH levels 24 hours
after the start of Lupron administration.
LUTEAL PHASE - The days of a menstrual cycle following ovulation and
ending with menses, (usually lasting between 12 and 14 days.)

couple's infertility is attributed to the man.
MENSTRUAL CYCLE - See Menstruation.
MENSTRUATION (MENSTRUAL CYCLE, PERIOD) - A recurring cycle
(beginning at menarche and ending at menopause) in which the
endometrial lining of the uterus prepares for pregnancy. If
pregnancy does not occur the lining is shed in response to
stimulation from estrogen and progesterone. The "average" menstrual
cycle is 28 days, but can vary significantly from women to women.
Irregular periods do not usually effect fertility, but unusually
long periods or no periods may indicate a fertility problem. See a
fertility specialist now
MESA - Microsurgical Epididymal Sperm Aspiration. A procedure in which sperm are
obtained from the empididymis by aspiration or surgical incision.
METFORMIN (GLUCOPHAGE) - An oral medication first used to help
control diabetes. Recently, it has been found to facilitate
ovulation in some women with PCOS. Women who do not ovulate after
taking metformin may be able to ovulate when taking metformin in
combination with clomid. Using metformin may be a benefit to some
women with polycystic ovarian syndrome by allowing them to avoid the
injectable FSH medications. See a fertility specialist now
METRODIN - A preparation of follicle stimulating hormone (FSH) used
to stimulate development and maturation of follicles.
METRORRHAGIA - Menstrual spotting during the middle of the cycle.
MICROINSEMINATION - A laboratory technique in which sperm are
injected next to the egg cell surface to increase the likelihood of
fertilization.
MICROMANIPULATION - Procedure in which a single sperm is injected
under the outer layer of the egg to induce fertilization (see ICSI).
This procedure is used to treat male factor infertility.
MISCARRIAGE (SPONTANEOUS ABORTION) - A pregnancy that ends before
the fetus (growing baby) can survive outside of the uterus. During a
miscarriage, the fetus, placenta and sac of fluid around the fetus
are expelled from the uterus (sometimes not all of these are
expelled completely.) A miscarriage may occur because the fetus is
not developing properly or because the placenta is not attached
properly. In many cases the cause is not known. It is estimated that
miscarriages occur in about 15-20 % of all pregnancies. A
miscarriage does not preclude a normal pregnancy in the future. Most
miscarriages begin with light, painless bleeding. This is the
mothers blood and is not fetal blood. About 50% of the time this
bleeding stops, and there is no problem with the pregnancy. It's
possible at this stage to check for fetal heartbeat with an
ultrasound scan. In the remainder of the cases the bleeding
continues, the uterus contracts resulting in painful cramps, and a
miscarriage occurs. Most women who miscarry do so only once and the
risk for miscarrying again is not increased. However, women over 35
years of age are more liable to miscarry. Repeated miscarriage do
occur in some women, and can be due to several factors including:
genetic (chromosonal abnormalities), hormone and immune problems,
PCOS and more. PGD screening may be recommended where genetic
factors are suspected. See a fertility specialist now
MITTLESCHMERZ - Discomfort felt on one side of the lower abdomen at the time of ovulation.

ovaries of one woman, are donated for use by another.
OOCYTE RETRIEVAL - A surgical procedure, usually under sedation, to
collect the eggs contained with the ovarian follicles. The physician
inserts a needle into the follicle, draws out the follicle's fluid
and egg through the needle, and then places the fluid and egg into a
dish for further processing.
OVARIAN CYST (OVARIAN CYSTS) - A fluid-filled sac inside the ovary.
An ovarian cyst may be found in conjunction with ovulation
disorders, tumors of the ovary, and endometriosis. Cysts can vary in
size from small to large. Most are small and do not present any
symptoms. Some may cause abdominal pain. Most cysts are benign, but
some may be malignant and for this reason doctors check all cysts.
There are several types of cysts: Functional cysts: these cysts are
normal and form during ovulation. Endometriomas: these cysts develop
in women who have endometriosis and may be filled with thick, brown
blood which gives them the name chocolate cysts. Cystadenomas: these
are benign cysts and are often filled with a fatty liquid. Multiple
cysts: these can be caused by PCOS.
Functional or benign cystic tumors may occur with no symptoms, but
sometimes a cyst will be large enough to cause abdomenal pain or put
pressure on the urinary tract and restrict urine flow. Other
symptoms may include pain during sexual intercourse, and rarely,
large cysts may produce nausea, fever, and severe abdominal pain. In
women with endometriosis, ovarian cysts can cause pelvic pain,
painful periods and other symptoms. Cysts can be diagnosed with
pelvic exams, blood tests and ultasound. See also Chocolate Cyst.

are based on the detection of Luteinizing hormone (LH) which is
always present in the body in low concentration but is produced in
higher concentrations around the middle of the menstrual cycle when
it is released by the pituary gland. This "LH surge" lasts for about
3 days, and this is the time when a woman is likely to ovulate. Most
women ovulate 36 hours after the surge. The surge in LH is seen
first in the blood, and then, about 8-12 hours later, it is detected
in the urine. See a fertility specialist now
OVULEX - Brand name of a commercial product. A nutritional

PITUITARY, PITUITARY GLAND - A gland in the endocrine system. The
pituitary is located at the base of the brain just below the
hypothalamus and it controls hormonal factories throughout the body
including the gonads, the adrenal glands, and the thyroid gland. The
anterior lobe of the pituitary gland secretes several hormones
involved in controlling reproductive processes, including FSH
(follicle-stimulating hormone) and LH (luteinizing hormone.) The
pituitary gland is about the size of a pea and is sometimes called
the "master gland" of the endocrine system because it controls many
of the other glands. In turn, the pituitary gland is controlled by
the hypothalamus. See also Endocrine System. See a fertility
specialist now

and provides a mechanism for exchanging the baby's carbon dioxide
and waste products for the mother's nutrients and oxygen. The baby
is connected to the placenta by the umbilical cord.

prolactin in the blood can reveal hypothalmic-pituitary disorders
that may hinder ovulation.
PROSTATE GLAND - A gland encircling the male urethra that produces
some of the fluid in semen, including a chemical that liquefies the
coagulated semen twenty minutes to one hour after entering the
vagina.

REPRONEX (hMG) - A medication used to replace the pituitary hormones
LH and FSH. Similar to Humegon and Pergonal. May be used to induce
ovulation in women who do not respond to clomiphene citrate
(Clomid.) Also used with women who do not normally produce estrogen
because of a pituitary gland or hypothalamic malfunction. May also
be used with men to stimulate sperm production.
RESISTANT OVARY - An ovary that cannot respond to the follicle-
stimulating message sent by FSH.
RETROGRADE EJACULATION - A male fertility problem where sperm
travels into the bladder instead of out of the penis due to a

RETROVERTED UTERUS - A uterus that is tilted back toward the rectum.
RH FACTOR - Genetically determined antigens present in the red blood
cells of most people and capable of inducing intense immunologic
reactions. Some women develop a sensitivity to Rh during pregnancy.
If a woman is Rh negative and her husband is Rh positive, she is a
candidate for Rh incompatibility problems. After the first
pregnancy, the Rh factor enters the Rh-negative mother's circulatory
system during the delivery (or miscarriage) of a child who has
inherited the Rh factor from his father. The mother's body then
produces antibodies against it. If she becomes pregnant with another
Rh-positive baby, the antibodies cross the placenta and attack the
baby's red blood cells, causing mild to serious anemia in the baby.
The medication Rhogam is given to prevent these problems.
RHOGAM (Anti-D) - A medication given to Rh-negative women after a
miscarriage, stillbirth, or live birth to prevent production of
antibodies in any Rh-positive babies they may have in future
pregnancies.
RUBELLA TITER - A blood test that determines if the patient is
immune to rubella (German measles), (a viral disease that can cause
severe birth defects). If a woman is not immune to rubella, she may
be advised to have a rubella vaccination, wait three months before
attempting pregnancy, and then re-test for immunity.

grow and gain their ability to swim. Sperm take about ninety days to
reach maturity.
SPERM MORPHOLOGY - A semen analysis factor that indicates the number
or percentage of sperm in the sample that appear to have been formed
normally. Abnormal morphology includes sperm with kinked, doubled,
or coiled tails. The higher the percentage of misshapen sperm, the
less likely fertilization can take place. See a fertility specialist
now
