Infertility
Significant social and medical problem affecting
couples worldwide
 Average incidence of infertility is about 15%
globally
 varies in different populations
 Some causes can be detected and treated, whereas
others cannot
 unexplained infertility constitutes about 10% of
all cases
Inability to conceive after 12 months of having
sexual intercourse with average frequency (2 to 3
times per week), without the use of any form of
birth control.
 Primary infertility
 couple has never produced a pregnancy
 Secondary infertility
 woman has previously been pregnant, regardless of
the outcome, and now is unable to conceive
 The chances of conceiving in any given
menstrual cycle is less than 20%
 Main events necessary for pregnancy to occur
are:
 ovulation
 fertilization
 implantation
Any condition that interferes with these events
may result in infertility

Intercourse just before ovulation maximizes the
chance of pregnancy
 Sperm survives as long as 5 days in the female
genital tract
 Ovum life expectancy is about 1 day if not
fertilized
 Sperm should be available in the female genital
tract at or shortly before ovulation
 Gonorrhea and chlamydia can cause:
 in women: pelvic inflammatory disease (major cause of
tubal infertility) and cervicitis
 in men: urethritis, epididymitis, accessory gland
infection
 Mumps, leading to orchitis, may cause secondary
testicular atrophy
 Other infections that may affect fertility include
tuberculosis, malaria and leprosy.
 Age of the woman
 after 40 the fertility rate decreases by 50% while the
risk of miscarriage increases
 Age of the man
 increased age affects coital frequency and sexual
function
 Nutrition
 for women, weight 10% to 15% below normal or
obesity may lead to less frequent ovulation and
reduced fertility
 Factors that can contribute to fertility
problems include:
 smoking and alcohol
 All these factors may cause:
 in women: reduced conceptions and increased
risk of fetal wastage
 in men: reduced sex drive and sperm count
 Vagina capable of receiving sperm
 Normal cervical mucus to allow sperm passage
 Ovulatory cycles
 Patent fallopian tubes
 Uterus capable of developing and sustaining
pregnancy
 Adequate hormonal status to maintain
pregnancy
 Adequate sexual drive and sexual function
 Normal immunologic responses to
accommodate sperm and conceptus
 Adequate nutritional and health status to
maintain nutrition and oxygenation of placenta
and fetus
 Normal spermatogenesis in order to fertilize
egg:
 sperm count
 motility
 biological structure and function
 Normal ductal system to carry sperm from the
testicles to the penis
 Ability to transmit sperm to vagina achieved
through
 adequate sexual drive
 ability to maintain erection
 ability to achieve normal ejaculation
 placement of ejaculate in vaginal vault
 Pelvic inflammatory disease (PID) leading to
blocked or damaged fallopian tubes
 may interfere with fertilization and transport of
egg
 Ovarian dysfunction resulting in absent or
diminished egg production
 Local factors in the uterus and cervix
 may interfere with implantation and woman’s ability
to carry pregnancy to term
 Luteal phase defect
 results in low production of progesterone
 may lead to early miscarriage
 Conditions that affect quality or quantity of
sperm may lead to infertility
 These conditions include:
 varicocele
 primary testicular failure
 accessory gland infection
 idiopathic low sperm motility
 Psychological
 sexual behavior may reflect couple’s desire not to
have children
 Immunological incompatibility
 may cause sperm agglutination
 Unknown causes
Evaluating both partners is essential
 Detailed history and physical
examination for both
 Semen analysis
 Evidence of ovulation
 Evidence of fallopian tubes
patency.
 Couple should be informed
about:
 different causes of infertility
 tests and procedures required to
make a diagnosis
 various therapeutic possibilities
 Couple’s interview is conducted
together as well as separately to
obtain confidential information

 General history
 occupation and background
 use of tobacco, alcohol and drugs
 history of abdominal surgery and earlier
diseases/infections
 Sexual history
 sexual disturbances or dysfunction such as
vaginismus, dyspareunia or erectile dysfunction
 sexually transmitted infections
 Reproductive history
 Gynecological history
 Age at menarche
 Menstrual periods: duration and intervals
 Previous contraceptive use
 Previous testing and treatment for infertility
Ovulation can be established based on:
 Urine test
 measures the LH in urine to detect if and when
ovulation occurred
 Basal body temperature chart
 temperature is measured every morning, before
woman gets out of bed
 elevation in temperature indicates ovulation
 Progesterone test
 progesterone level in blood is measured on days 21 or
22 of 28-day cycle
 Endometrial biopsy
 done during premenstrual phase
 detects if endometrium undergoes expected changes
(consistent with ovulation and production of
progesterone)
 Hysterosalpinogram (HSG)
 to determine whether fallopian tubes are blocked
 Laparoscopy
 to evaluate for pelvic disease, such as endometriosis,
and check patency of fallopian tubes
 Hysteroscopy
 to evaluate condition of uterine cavity (polyps, fibroids)
Semen is studied for a number of factors including:
 Volume (1.5 cc to 5.0 cc)
 Number of sperm present (> 20 million/ml)
 Sperm motility (> 60%) and forward
progression .
 Morphology (> 60% normal forms)
 Presence of any infection
 Urine analysis: to rule out infection
 Endocrine tests: to measure concentrations of
hormones testosterone, FSH and LH
 Sperm penetration assay: to establish ability of
sperm to penetrate egg
 Postcoital test (low validity): to establish ability
of sperm to penetrate cervical mucus

Suppressing hormones
or surgical procedure
 Involves the use of medication to stimulate
development of one or more mature follicles
 Success rates vary considerably and depend on
age of the woman, the type of medication used,
whether there are other infertility factors
present in the couple and other reasons

into the circulation
human menopausal gonadotropin ,
which contains equal quantities of
FSH and LH
Bromocriptine suppresses production of prolactin
 A fertility procedure in which sperm are washed,
concentrated and injected directly into a woman’s
uterus
 Increases the number of sperm in the fallopian
tubes
 Not recommended in cases of tubal blockage, poor
egg quality, ovarian failure and severe male factor
infertility
 Most successful when coupled with drugs inducing
ovulation (success rates of 5% to 20% per cycle)
 Noncoital methods of conception
 Includes all fertility treatments in which both
eggs and sperm are manipulated
 Types of ART include:
 In Vitro Fertilization (IVF)
 Zygote Intrafallopian Transfer (ZIFT)
 Gamete Intrafallopian Transfer (GIFT)
 Involves retrieving eggs and sperm from female
and male partners and placing them in a lab
dish to enhance fertilization
 Fertilized eggs are transferred several days later
into the uterus
 Ovarian stimulation drugs are used prior to
procedure in order to retrieve several eggs and
maximize chances for successful fertilization
 Success rates are about 20% per egg retrieval
 GIFT is a procedure that involves:
 ovarian stimulation
 retrieval of eggs
 placing a mixture of sperm and eggs directly into the
woman’s fallopian tube
 GIFT does not allow visual confirmation of
fertilization
 Success rates per egg retrieval are about 28%
(higher than for IVF)
 ZIFT, also called tubal embryo transfer, is
another variation of IVF
 As with IVF, the actual fertilization takes place
in a lab dish
 Fertilized eggs are placed directly into a
fallopian tube
 Success rate is about 29% per egg retrieval
 Involves injection of single sperm into the egg
 The woman is administered fertility drugs prior
to the procedure to aid in the production of
multiple eggs
 Only active undamaged sperm are selected for
injections
 Eggs are observed to see if fertilization takes
place
 average fertilization rate is 65%
 Implantation into the uterus takes place within
72 hours after ICSI
 Success rates range from 15% to 35% per egg
retrieval
 Surgical treatment in some cases (varicocele)
 Intrauterine insemination can be performed
either with patient’s or donor’s sperm
 ART procedures:
 GIFT
 IVF
 ICSI
Donor semen should be free from STDs/HIV
 Infertility is a significant social and medical problem
affecting couples worldwide
 Female and male factors are equally responsible
 Evaluation of both partners is essential
 Treatment depends on the cause of infertility and
varies from ovulation-inducing drugs to surgery
to ART
