Abstract

The aim was to investigate the relationship between the presence of the meiotic spindle (MS) and zona pellucida (ZP) birefringence of MII oocytes with morphokinetics variables of derived embryos in ICSI setting. Using a polarization imaging system, the ZP birefringence and presence of MS were evaluated pre ICSI. Also, morphokinetics variables including time of second PB extrusion (tPB2), time of pronuclei appearance (tPNa), time of pronuclei fading (tPNf), time of two to eight discrete cells (t2-t8) ECC1 (t2-tPB2), cc2a (t3-t2), S2 (t4-t3) and S3 (t8-t5) as well as irregular cleavage events of 368 embryos were analyzed with time lapse monitoring (TLM). t5 occurred earlier in high birefringent ZP (HB-ZP) compared with low birefringent oocytes (LB-ZP; p = 0.001). In addition, t2 happened later in invisible MS compared to visible MS oocytes (p = 0.013). There were significantly lower rates of cell fusion (Fu) in oocytes with HB-ZP and also the Fu and trichotomous mitoses (TM) together in visible MS oocytes (p = 0.005, p = 0.001 and p = 0.001, respectively). Both t2 and t5 timings and irregular cleavage events of embryos were correlated with ZP birefringence and MS status, respectively. So, combining the information from both oocyte polarization microscopy imaging and embryo TLM can be a useful tool for single embryo transfer (SET) program.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 04 May 2017.
All research outputs
#8,498,161
of 9,768,421 outputs
Outputs from Archives of Gynecology & Obstetrics
#708
of 946 outputs
Outputs of similar age
#219,342
of 263,138 outputs
Outputs of similar age from Archives of Gynecology & Obstetrics
#18
of 25 outputs
Altmetric has tracked 9,768,421 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 946 research outputs from this source. They receive a mean Attention Score of 3.8. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 263,138 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 25 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
