A Conjoined Oocytes Within One Follicle Have Infrequently Been Practical In Human Assisted Reproduction Thus Indication For The Hypothesis That Some Of The Polyovular Follicles Recognized From Histological Studies Of The Ovary May Persist Awaiting Ovulation. Image Illustrate Immature Oocytes In W
Sperm DNA compressed into toroids are exposed by acidified Triton X-100 and DTT pre-treatment (Biomed Res Int. 2015;2015:780983). DNA damage (darker color) is revealed following simple staining (Diff-Quik or Hema 3). "ROC calculated cut-off was >70.0% for normal toroid integrity (sensitiv
Implanted mouse embryo (Arch Gynecol Obstet. 2015;291:647) showing a dark central group of cells (inner cell mass or ICM) that becomes the fetus while the surrounding trophoblasts give rise to the placenta.

Dual use of Diff-Quik (Hema 3) for both strict morphology and chromatin integrity (Hum Reprod. 2009;24:28) can be improved (J Reprod Med. 2015;60:6) by an immediate post-stain 1-minute soak-in-water step to distinguish DNA damaged sperm which then appear as dark purple-blue sperm. This is due to
Difference between WBC and Spermatids
The multinuclear cell is a result of incomplete spermatogenesis resulting in undivided spermatids as an abnormal round cell. Spermatids with cytoplasm are at the stage just before sperm formation. Diff-Quik stained. 500x
