P-033 clinical implications of using a second ejaculate sample in In-vitro fertilization Open
Study question Dose using the second ejaculate, collected 2-3 hours after the first, improve clinical outcome in IVF treatments? Summary answer Using the second ejaculate sample resulted in significantly higher clinical pregnancy rates. Wh…

Pregnancy Outcomes, Miscarriage and Live Birth Rates Following the Transfer of Thawed Vitrified Embryos Derived from IVF vs. ICSI, A Retrospective Analysis Open
The present study was conducted to compare embryo survival rate and treatment outcomes including pregnan-cy, miscarriage and live birth rates of IVF and ICSI vitrified-thawed embryo transfers. Authors suggested to compare treatment outcome…
P-216 Evaluation of embryo quality and morphokinetics following short exposure of oocytes to spermatozoa Open
Study question Does embryo quality and morphokinetics following short exposure of oocytes to spermatozoa differ from conventional long exposure? Summary answer No statistical differences were found in embryo quality and morphokinetics foll…
P-413 Lessons learnt from a long-term fertility cryopreservation program regarding usage-rate of vitrified oocytes and embryos Open
Study question Does woman's age during cryopreservation affect usage-rate of the vitrified oocytes and embryos from fertility preservation cycles? Summary answer The usage-rate of vitrified oocytes and embryos from cryopreservation cycles …
P-050 Using a second sample of ejaculate for IVF treatment Open
Study question Is it beneficial to use the second sample of ejaculate collected within 2 hours from the previous sample to fertilize the oocytes in IVF treatments? Summary answer A significantly higher clinical pregnancy rate was achieved …
Embryo fragmentation – Is it really a detrimental factor? Open
Purpose : To learn what is the implantation potential of fragmented embryos that underwent morphokinetic evaluation in a time-lapse incubator. Methods: A retrospective study analyzing 4,210 Day 5 embryos incubated in a time-lapse incubator…
O-081 Brad Pitt or the Next Door Neighbor? Open
Study question Can we identify the preferences of sperm recipients regarding traits of the ideal sperm donor? Summary answer According to our questionnaire, patients’ priority was a “healthy child” but they were also trying to assemble “th…
P-209 Overweight and obese women have slower developing embryos and a lower rate of morphokinetic top-quality blastocysts compared to underweight and normal weight women Open
Study question Does maternal body mass index affect embryo morphokinetics and the rate of top-quality blastocysts Summary answer Overweight and obese women had slower developing embryos and a lower rate of top-quality blastocysts compared …
View article: P-062 Morphokinetic embryo division timings and top-quality cleavage and blastocyst rates are unaffected by sperm quality
P-062 Morphokinetic embryo division timings and top-quality cleavage and blastocyst rates are unaffected by sperm quality Open
Study question Does testicular extracted sperm affect embryo morphokinetics and the rate of top-quality cleavage and blastocyst embryos. Summary answer Sperm origin, whether ejaculated normal sperm or testicular extracted sperm, was not fo…

Time interval between hCG administration and oocyte pick up: analysis of oocyte maturation, embryonic morphology, morphokinetics, and IVF outcome Open
Objective: To investigate associations of the time interval between hCG administration and oocyte pick up with oocyte maturation, embryonic morphology, morphokinetics, and IVF outcome, in different age groups. Design: A retrospective cohor…

Improving embryo selection by the development of a laboratory-adapted time-lapse model Open
A model based on laboratory-specific morphokinetics was found to be complementary to general models and an important additive tool for improving single embryo selection. Developing an in-house laboratory-specific model requires many stages…
Live Birth from the Transfer of a Severely Fragmented Embryo Observed by Morphokinetics Open
We report a live birth from a heavily fragmented embryo which continued cleavage to a fully expanded blastocyst. A 32‐year‐old patient underwent 2 IVF cycles without achieving pregnancy. In the first cycle, 2 embryos with fragmentation wer…
Dormancy in Embryos: Insight from Hydrated Encysted Embryos of an Aquatic Invertebrate Open
Numerous aquatic invertebrates remain dormant for decades in a hydrated state as encysted embryos. In search for functional pathways associated with this form of dormancy, we used label-free quantitative proteomics to compare the proteomes…
