Infertility.
 Def - Infertility refers to an inability to conceive
after having regular unprotected sex.
 It is a significant social and medical problem
affecting couples world wide.
 Average incidence --15%
 Unexplained infertility constitutes about 10 % of all
cases.

Definition.
 Infertility is the failure
to achieve a birth ever a
12 months period of
unprotected
intercourse.
 Infertility is the inability
of a sexually active non
contracepting couple to
achieve pregnancy in one
year.

Defect.
20 % defect
in men
40-50 in
women.
30% in
both

Causes of infertility in men
 Low sperm count:
 Less than 10 million sperm per ml of semen.
 Normal count is 35 million sperm per ml of
semen or more.
 No sperm: - Absence of sperms in semen.

Causes of infertility in men
 Low sperm motility:
 Sperms are immotile, can not
swim.
 Abnormal sperms:
 (Unusual shape , more
difficult to move and fertilize
egg)
 Its causes are:
 Testicular infections.
 Testicular cancer.
 Testicular surgery.

Other causes.
 Hypogonadism (testosterone deficiency).
 Genetic abnormality.
 Mumps (testicular inflammation).
 Hypospadiasis.
 Chlamydia infection
 Ejaculation disorders (Retrograde ejaculation).
 Variocele (includes varicose vein in scrotum).
 Undescended testicles.
 Overheating testicles.

Causes of infertility in women.
 Ovulation disorders:
 Premature ovarian failure
(before age of 40)
 Polycystic ovary syndrome.
 Hyper-prolactinemia (in non
pregnant state)
 Poor egg quality.

 Defect in uterus &
fallopian tubes:
 Surgery.
 Sub-mucosal
fibroids.
 Endometriosis.
 Previous sterilization
treatment

 Drugs:
 NSAID’S (aspirin & ibuprofen).
 Chemotherapy.
 Radiotherapy.
 Illegal drugs.

Types.
Primary.
When a women is unable to
ever bear child
Secondary.
When a women has been
pregnant but
failure to achieve live birth
after having a live
birth previously.

Diagnosis.

Treatment.
 In males
 In females.

Treatment in males.
 Blockage of the
ejaculatory duct
 Sperms can be extracted
directly from the
testicles and injected
into an egg in laboratory.

Surgery for epididymal
blockage
 A bypass of the blockage
can be performed, called
vaso-epididymostomy
(vas deferens is re-
connected to epididymis ).

Retrograde ejaculation
 Sperms can be taken
directly from the
bladder and injected
into an egg in
laboratory.

Others.
 Premature ejaculation
or Erectile dysfunction
 Behavioral approaches
(giving suggestions) or
medications.
 Variocele
 If there is varicose vein
in scrotum, it can be
surgically removed.

Treatment in females.
• Stimulate ovulation by inhibiting
production of prolactinBromocryptine
• Given in combination (clomiphine + HMG
+ FSH)
• It stimulates follicles to ovulate
Human
Chorionic
Gonadotrophin
• To encourage ovulationClomifine

Treatment in females.
• Clients who do not respond to clomiphine.
• Especially when client with PCOS linked to
insulin resistance.
Metformin
• Controls estrogen production by ovaries.
• It stimulate ovaries to mature egg follicle.
• Ex: Gonal-F, Repronex,Follistim,(given S/C)
FSH
• Genetically engineered products. Contains
both FSH & LH.
• In case of absent ovulation due to pituitary
dysfunction
Human
Menopausal
Gonadotropin.

COUNSELING
 Deals with the
psychosocial impact of
infertility in terms of :
 Intervention,
 Treatment, and
 After-effects of both
successful and unsuccessful
treatments.

COUNSELING
 It also involves therapeutic work to help
patient cope with the consequences of
infertility & treatment.

Objectives of counseling.
 Informed consent.
 To offer coping strategies to couples.
 To facilitate decision making.
 To offer preparation for procedures.
 To help client in achieving a better quality of life.
 To provide genetic counseling.

Advantages
 Helps to deal with the emotional stress.
 Provide extra support.
 Allow the client in exploring all possible
options for family.

Advantages……
 Help the couples in overcoming the
dilemmas & deciding the right fertility
treatment.
 Explains about the infertility management &
specific treatment.

ASSISTED REPRODUCTION
TECNOLOGY (ART) - ETHICAL & LEGAL
ASPECT
 Aim –
 Is to promote the
chances of fertilization
and
 Subsequent pregnancy
by bringing the sperm
and egg close to each
other.

Invitro – fertilization.
 Is a process by which an egg is fertilised by
sperm outside the body: in vitro.
 Babies conceived as the result of IVF, are
called “Test tube babies”.

History.
1890
• The very first in vitro manipulation of eggs/ embryos was performed by Walter Heape
, when he transferred in vivo fertilized eggs from one female rabbit to another.
1959
• M.C. Chang, successfully conducted IVF in rabbits.
1969
• the journal Nature published a paper authored by R.G. Edwards, B.D. Bavister and P.C.
Steptoe: “Early stages of fertilization in vitro of human oocytes matured in vitro”
1977
• The first IVF pregnancy in human and the birth of Louise Brown

Indian history.
 Dr. Subhash Mukhopadhyay
(16 January 1931 – 19 June
1981) was a physician from
Kolkata, India, who created the
world's second and India's
first child using in-vitro
fertilisation, Durga who was
born 67 days after the first IVF
baby in United Kingdom.

Indications.
 Tubal disease. In women with blocked fallopian tubes,
IVF has largely replaced surgery as the treatment of
choice.
 Endometriosis. Patients with endometriosis, often have
tubal involvement and ovarian cysts (endometrioma).
 Ovulatory dysfunction. In patients with polycystic
ovarian disease (PCOS) and other ovulatory problems.

Indications.
 Age Related Infertility.
 In normal reproductive life, a woman's ovarian function is diminished with
age. In many cases, this reduced function can be overcome through the use
of IVF
 Male Factor Infertility.
 Azoospermia, oligozoospermia, asthenozoospermia, anti-sperm antibody.
 Preimplantation Genetic Testing (PGT).
 Genetic testing on preimplantation embryos may be indicated for patients
who are at risk for genetic disorders such as Cystic fibrosis and Thalassemia

Process.
 Initial evaluation
 Suppression of natural hormonal cycle
 Ovarian stimulation
 Collection of oocytes
 Collection of sperms
 In vitro fertilization of oocytes
 Embryo transfer

Initial evaluation
 Blood tests
 Seminal Fluid
examination
 Hysterosalpingogram
 Trans vaginal
ultrasound

Suppression of natural
hormonal cycle
 Oral contraceptive pills – each day starting cycle day 1, 2
or 3 for approximately 2-4 weeks
 Lupron / Leuprolide Acetate – GnRH Agonists. It
suppresses LH surge preventing eggs from being released
before they are mature for egg retrieval. Subcutaneous inj
every morning
 Nafarelin - GnRH Agonists, three times a day nasal spray.
 Ganirelix Acetate Injection / Cetrotide – GnRH
antagonists

Ovarian stimulation
 Produce multiple mature follicles, rather than
the single egg normally developed each month.
 Produces many good follicles to be Fertilized.
 Multiple eggs are stimulated because some
eggs will not fertilize or develop normally after
fertilization.
 Regular monitoring by ultrasound scan is
done.

Collection of oocytes
 The oocyte maturation is performed, generally by
an injection of human chorionic gonadotropin
(hCG). Commonly, known as the "trigger shot.“
 The egg retrieval is performed at a time usually
between 34 and 36 hours after hCG injection.
 Egg retrieval is usually accomplished by
transvaginal ultrasound aspiration.

Collection of oocytes
 It is done under short general anesthesia, and is 20
to 30 minutes procedure.
 In some circumstances, one or both ovaries may
not be accessible by transvaginal ultrasound.
Laparoscopy may then be used to retrieve the eggs
using a small telescope placed in the umbilicus.

Collection of sperms
 Shortly before or after the oocyte collection the
male partner will be asked to give a sperm
sample.
 Sexual abstinence of 3-4 days should b exercised.
 Collected about 60-90 minutes prior to
fertilization,.

Collection of sperms
 Liquefied ,centrifuged, suspended in culture medium,
and incubated for 30-60 mins at 37⁰ C.
 The most active sperms are located in the surface of
the medium.
 Sperm may be obtained from the testicle, epididymis,
or vas deferens from men whose semen is void of
sperm either due to an obstruction.

In vitro fertilization of oocytes
 Fertilization is started by adding 10,000-
50,000 motile sperms to about 100 μl to 1 ml
culture medium in which the oocytes is being
incubated.
 Intra-cytoplasmic sperm injection (ICSI) is
indicated in cases where semen fluid does
not contain sperm.

Types.
 Intra-uterine Insemination (IUI)
 In- vitro fertilization (IVF)/ Embryo transfer
 Intracytoplasmic sperm injection (ICSI)
 Gamete intra-fallopian transfer (GIFT) &
 Zygote intra-fallopian transfer (ZIFT)

Intra-uterine
Insemination(IUI)
 First line
 Indications
 Hostile cervical mucus
 Anti-sperm or male
fertility problem (low
sperm count or premature
ejaculation)
 Although tubal patency of
female partner must be
assured

In- vitro fertilization (IVF)/
Embryo transfer
 Fertilization occurs
outside the body.
 Indications
 Uterine tube occlusion
 Endometriosis or
cervical mucus
problems,
 where male factors
are main problem

Intracytoplasmic sperm
injection (ICSI)
 The injection of a single
sperm into the cytoplasm
of an egg with a fine glass
needle.
 Useful technique when
sperm quality is poor.
 In azoospermic man sperm
can be obtained surgically
from the epididymis or by
extraction from testis itself.

Intra-cytoplasmic sperm
injection (ICSI)
 An embryologist
isolates a sperm cell,
draws it up into a
microscopic needle and
injects it inside an
oocyte using a high
power microscope.
 Fertilisation check is
performed the next day

injection (ICSI)
 Approximately 18 hours
after sperm injection or
insemination of the
eggs.
 Usually 65% to 75% of
mature eggs will
fertilize after
insemination

injection (ICSI)
 They are cultured in special incubators to
support division and development.
 If the couple has a history of certain genetic
disease and the gene that is causing that
problem is identified, a pre-implantation
genetic diagnosis may be done.

Embryo transfer
 Performed on day 2, 3 or 5
post fertilization.
 One or more embryos
suspended in a drop of
culture medium are drawn
into a transfer catheter, a
long, thin sterile tube with a
syringe on one end.

Embryo transfer
 The physician gently
guides the tip of the
transfer catheter
through the cervix and
places the fluid
containing the embryos
into the uterine cavity

Embryo transfer
 Related to age and embryo quality
 o <35 = 2
 o 35-37 = 2-3
 o 38-40 = 3-4
 o >40 = up to 5
 For patients with 2 or more failed IVF cycles, or a poor
prognosis, can add more based on clinical judgement

Variations of IVF
 Gamete intrafallopian
transfer (GIFT)
 Zygote intrafallopian
transfer (ZIFT).

Gamete intra-fallopian transfer
(GIFT) & Zygote intra-fallopian
transfer (ZIFT)
 Laparoscopic technique that offer little
clinical advantage over invitro fertilization
(IVF)
