Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
To study the chromosomal content of spermatozoa that could be selected for intracytoplasmic sperm injection (ICSI) in cases of macrocephalic sperm head syndrome. Case report. Obstetrics, gynecology, urology, and reproductive biology departments. Two infertile patient candidates for ICSI presenting with total teratozoospermia (100%) with mainly large-headed spermatozoa (91% and 82%, respectively). Fluorescence in situ hybridization with X, Y, 18 centromeric probes on unselected spermatozoa (all migrated spermatozoa) and specifically on selected spermatozoa with normal-sized heads. Percentage of polyploid, diploid, aneuploid, and normal haploid spermatozoa, according to X, Y, 18 chromosome centromeric probes on selected spermatozoa (head size compatible with ICSI). All the nonselected spermatozoa were abnormal, diploid, or polyploid. The rate of normal ploidy (haploid cells) among the selected sperm population was 1 per 28 for patient 1 and 5 per 51 for patient 2. This very low proportion of normal haploid spermatozoa among selected spermatozoa contraindicated ICSI for the two patients. We suggest performance of this selection and analysis before including (or not), in an ICSI program, patients with macrocephalic sperm head syndrome, associated or not with preimplantation genetic diagnosis.
