ANEUPLOIDY
10% of eggs are aneuploidic in young
women
30% at the age of 40
50 % at the age of 43
Nearly all the eggs are aneuploidic at the
age of 45

OVARIAN RESERVE
Age is an important independent
determinant of
fertitlity and miscarriage
But due to considerable individual variation
in the
age of menopause and age of subfertility.
Chronological age ALONE is a POOR
indicator of reproductive aging, and
thus of the ovarian reserve.

AMH
AMH is a glycoprotein
Originally known as Mullerian Inhibiting
Substance(MIS)
Appears in females at puberty
Produced by granulosa cells of pre-antral and
small
antral follicles of 4-6 mm
AMH is not expressed in atretic follicles and
theca cells.
26. 26
AMH is produced by the small growing (primary andAMH is produced by the small growing (primary and
preantral) follicles in the postnatal ovary and has two sites ofpreantral) follicles in the postnatal ovary and has two sites of

The intrafollicular concentrations of AMH
in
normal human antral follicles show a
gradual
reduction as the diameter of the follicle
increases, and a sharp decline is
observed
around 8mm
Physiological function- prevent excessive
follicle recruitment. Acts as a

Understanding AMH measurement methods
AMH is measurable in serum
TWO METHODS AVAILABLE ARE
Diagnostic system Lab ( DSL) (ng/ml)
Immunotech Beckman Coulter ( IBL) assay.
( pmol/l)
NEW METHOD : AMH Generation II

AMH
Increasing age means a decreasing AMH
level
Lower AMH levels at any given time
irrespective of age predicts a poor
response
to ART.
High AMH levels – candidates prone for
OHSS.
36. 36
ADVANTAGE OVER OTHER ORT MARKERS
It is the earliest marker to change with
age
It shows the least intercycle and
intracycle
variability
It can be randomly measured during the
cycle
It shows no modifications during GnRHa
It needs no modification in hypothalamic
amenorrhea
It is both more convenient and
informative
than basal FSH

INDIVIDUALISED AMH TAILORED COH
Improves embryo transfer rates, the
incidence of fertilization, pregnancy and
live birth rates.
Reduces incidence of adverse outcomes,
such as OHSS and failed fertilization

PROPOSED AMH BASED PROTOCOLS
Low AMH (< 1.4 ng/ml)
Cycle cancellation or poor response
a. Inform the patient about the cycle
cancellation
or no transfer
b. Low possibility of pregnancy
c. Avoid long suppression
d. Antagonist cycle
e. Use of HMG for stimulation
Normal AMH (1.4-3.5 ) Normal
Response
a. Standard protocol
39. 39
PROPOSED AMH BASED PROTOCOLS
HIGH AMH (> 3.5 ng/ml)
a. Inform about the risk of OHSS
b. Avoid depot GnRHa
c. Low FSH dose
d. Antagonist cycle preferred
e. Agonist Trigger
f. Blastocyst transfer or Freeze all embryos
and transfer later.

CONCLUSION
Anti mullerian hormone (AMH) alone
or best in combination with
antral follicular count (AFC)
is the
BETTER INDICATOR
of ovarian reserve
than any other hormonal or
sonographic markers available at
present.
