COVID-19 and assisted reproductive technology services: repercussions for patients and proposal for individualized clinical management.

abstract：BACKGROUND:Flow cytometric sorting can be used to separate sperm based on sex chromosome content. Differential fluorescence emitted by stained X- vs. Y-chromosome-bearing sperm enables sorting and collection of samples enriched in either X- or Y-bearing sperm for use to influence the likelihood that the offspring will ...
