Four Landmark Innovations
• ICSI (Intra-cytoplasmic sperm injection)
Optimizes fertilization
• Blastocyst Culture
Allows for developmental selection
• CCS (Complete Chromosomal Screening)
Determines which embryos have the normal 23 pairs of
chromosomes
• Vitrification
Superior freezing technique allows for outstanding survivability of
embryos and therefore a delayed transfer (FET) with higher
implantation rates over a fresh transfer
Vitrification and subsequent FET
Vitrification and subsequent FET
Comparing platforms
• ICSI and day 3 embryo transfer
12 eggs/ 10 mature/ 8 fertilize
Eight 6-8 cell embryos on day 3
Multiple embryo transfer, risk of multiples, decreased pregnancy
rates, poor prognosis embryos cryopreserved
• ICSI, blastocyst culture, CCS, subsequent FET
12 eggs/ 10 mature/ 8 fertilize
Four ~ 150 cell blastocysts on day 5/6
Three determined to be euploid
One transferred in a subsequent FET with 70+ % FHT rate
Excellent prognosis embryos cryopreserved

Methods

•
•
•
•
Retrospective cohort study. 396 patients undergoing IVF from 10-12010 thru 1-1-2014 at Conceptions in Colorado were offered a CCS
cycle with subsequent FET.
These data include all patients that desired to use their own oocytes
with ICSI.
Embryos were cultured in sequential media to day 5 or 6, hatched,
and laser biopsied.
Biopsied embryos were vitrified using a closed system and stored for
subsequent FET.
SNP analysis was performed by Natera (San Carlos, CA).
1-2 embryos were warmed and transferred (FET)at a later date when
the uterine environment was optimal

Conclusion
•
•
•
•
24 chromosome aneuploidy screening with vitrification allows
patients the opportunity to obtain embryos with high
reproductive potential while ensuring endometrial synchrony.
A significant percentage of embryos were aneuploid,
particularly in women of advanced reproductive age and/or
possessing decreased ovarian reserve.
Identifying aneuploid embryos before transfer allows for the
elimination of the number one cause of failed IVF, miscarriage
and abnormal amniocentesis.
Chromosome screening allows for patients with an AMH < 1.5
the ability to achieve a viable pregnancy utilizing elective
single embryo transfer.

Finer Points
•
•
•
•
SNP microarray evaluates 300K random BP changes in the
non-coding regions of the chromosome, compares data with
parental samples, integrates known data from the Human
Genome Progect.
aCGH flourescently labels embryo DNA (red), reference DNA
(green), samples mixed and hybridized to an array which
contains multiple probes corresponding to each chromosome.
Trisomies red, monosomies green.
aCGH can have up to an 8.5 – 11.5 false negative rate (calling
an embryo normal when it is not) b/c it cannot detect
haploidy (set missing, n =23), some forms of triploidy (extra set,
n = 69), UPD (both sets from one parent), del/dup.
If UPD of an imprinted (methylated/silenced) gene region,
then Angelmen, Prader-Willi.
Finer Points
Natera SNP advantage over aCGH
•
•
•
•
•
•
Individual confidences for accuracy of each call
Parental source of aneuploidy
Simultaneous single gene testing and 24 chromosome PGS on single
cell
Haploidy, polyploidy and UPD detection
Corrects for contaminant DNA
Confirmation of parentage
aCGH advantage over Natera SNP
• Chance of homozygosity in chromosome regions (blood relationship
in the couple can result in multiple areas of homozygosity and
potential for no-call across a particular chomosome)
Oocyte vitrification
Costs
20K for ovarian stim, retrieval, vit (x1), storage, thaw, fert, embryo culture, transfer.
Conservative number. Some women may need to stim, retrieve and vit more than once.
Efficacy
20% LB rate for women who freeze 6 eggs at 35
Medical v. “social”
If all women 35 who freeze 6 eggs use them in the future, at a 20% LB rate, at 20K per
cycle, then the NNT (number needed to treat) for 1 live birth is 5 at a cost of 100,000
- Table and tabulations of the 6 vit studies from Abusief and Adamson, OBG Mgmt, Feb 2015, v.27 No.2
Donor oocyte vitrification
Proven Success Rates – My Egg Bank (MEB) program has demonstrated success equal
to traditional fresh egg donation. Current CRA stats are 67% FHT for donor oocyte
vit transfers.
Economical – Full benefit of services with a significantly less out of pocket expense
than if using a fresh egg donor. $20,019 for 6 mature vitrified donor eggs, complete
MD/Nursing management of donor egg cycle, unlimited cycle laboratory assays
and ultrasound, thawing of eggs, sperm isolation, ICSI, culture of embryos to
blastocyst and transfer.
Convenience – Avoids the often lengthy match process and cycle coordination when
using a fresh donor. Expansive donor selection – large selection of frozen eggs from
donors that have passed rigorous medical, genetic and psychological testing.
College educated and come from diverse ethnic and racial backgrounds.
MEB offers a guarantee to its affiliate clinics. At least 3 oocytes must survive the thaw,
and that at least 1 - 6 cell, day 3 embryo is available. Failure to achieve either one
of these criteria and the recipient may choose another donor.
CCS is also available.

Lupron triggers where GnRH antagonist clears pituitary receptors and

Low dose prednisone
•

•
In women with RPL, safety and efficacy of prednisone 10mg BID thru
12 weeks demonstrated a livebirth rate of 77% in 80 women with
therapy as opposed to a 35% pregnancy rate in 52 matched women
without therapy. Concurrent use of 5mg folate QOD, 100mg ASA QD
(Tempfer et al, Fertil & Steril 2006, Vol 86(1) p. 145).
Reznikoff-Etievant et al, Human Reproduction 1999, Vol 14(8) p. 2106
also demonstrated safety of prednisone at 20mg/d in 277 women.
Women with recurrent loss had significantly more uNK than controls (p
= 0.008).
Prednisone treatment (20 mg/d for 21 days) significantly reduced the
number of CD56 cells in the endometrium, from a median of 14%
before to 9% after treament (p = 0.0004).
Demonstrated that high numbers of uterine natural killer cells in
preimplantation endometrium of women with recurrent miscarriage
can be reduced with the administration of prednisone (Quenby et al,
Fertil & Steril 2005, 84: p 980-4).
