11. Both FSH and LH are essential for normal
estradiol biosynthesis.
75 UI recLH is sufficient to promote optimal
follicular and endometrial growth as well as
androgen production in most HH patients.
Evidence suggests that in reproductive cycles
optimal follicular development occurs within an
‘LH window’, above a certain ‘LH threshold’ and
below an ‘LH ceiling’ (1.2 to ? UI/L).

28. Women with less sensitive ovaries (ovarian aging) have poorer
IVF outcomes.
Androgen secretory capacity decreases with ovarian ageing.
Mechanisms include decreased number of functional LH
receptors and ovarian paracrine activity resulting in reduced
LH bioactivity. LH-r polymorphisms possibly involved in hypo-
responders.
LH supplementation to COS is an evidence-based strategy to
maximize pregnancy results.
4 subgroups benefit of LH supplementation in COS:
Poor responders
Slow/hypo-responders
Age >35 years
Deeply suppressed endogenous LH levels
Esteves, 28
29. 3 subgroups clearly benefit of LH supplementation in
OI and IUI:
WHO group I anovulation
WHO group II clomiphene resistant
WHO group II with previous over-response to OS

Lower expression of LH/hCG receptor gene as well
as genes involved in in biosynthesis of cholesterol
and steroids in granulosa cells in pts. treated with
HMG preparations
May reflect down-regulation of LH receptors, as shown in animals:
Caused by a constant ligand exposure during the follicular
phase due to longer half life and higher binding affinity of
hCG to LHr
May explain the observed lower progesterone levels:
Caused by lower LH-induced cholesterol uptake, a decrease in
the novo cholesterol synthesis and a decrease in steroid
synthesis.

38. Recombinants vs Urinary products
Recombinant LH preparations have 3 major
differences compared to urinary products:
Higher purity and specific activity (SC delivery in
very small volumes))
Higher dose precision (FbM)
LH activity in u-HMG is hCG dependent:
hCG is concentrated during purification or added to
achieve the desired amount of LH-like biological activity;
hCG has higher half-life and biological activity compared to
rec-hLH.
Esteves, 38
39. Differences between rec-hLH and LH
Activity in HMG Preparations
Lower expression of LH receptor gene
in pts. treated with HMG (LH-r down-
regulation).
Preparations used for COS are
important for granulosa cell function and
may influence the developmental
competence of the oocyte and the
function of corpus luteum.

42. Steroidogenesis During Normal
Follicular Phase and Following COS
The expression of LH-R (GCs) is linked to the synthesis of
progesterone during COS.
Levels of LH-R and progesterone synthesis vary depending on
the hormones used during the stimulation protocol.
Esteves, 42 Steroidogenesis Consensus Meeting III, Copenhagen, Denmark, May 2011.
43. Steroidogenesis in COS
Endogenous LH then results in higher levels of progesterone
synthesis following treatment with FSH than hMG:
higher levels of LHR expressed on granulosa cells and
increased number of granulosa cells.

49. Serum Progesterone and IVF Outcome
Most circulating P4 (95%) is produced in the intrafollicular
compartment by the granulosa cells;
Intrafollicular P4 and Hydroxi-progesterone are terminal
products and cannot be converted to estradiol by GCs
under the effect of LH/hCG activity contained in hMG, due to
lack of expression of an hydrogenase and P450-17α needed
for this pathway;
Higher serum Progesterone increments are related with
more follicles developed and more oocytes retrieved and it’s
effect in pregnancy still controversial. Increments up to
>7nmol/L seems not to affect clinical pregnancy rates.
50. Serum Progesterone and IVF Outcome
Treatment with FSH results in higher levels of
progesterone than treatment with hMG.
A large number of developing follicles leads to
increased levels of progesterone.
The higher the level of LH present, the higher the
level of progesterone.
The effect of high progesterone levels at the time
of hCG administration on pregnancy outcome is
still controversial. Further detailed analyses are
required to understand why, when and how much
progesterone is detrimental for implantation rates.
