Conjoined Oocytes

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

DNA Damage in Sperm Toroids revealed by Triton X-100 and DTT Pre-treatment before Staining.

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 showing inner cell mass and trophoblasts.

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.

Simple Diff-Quik stain for chromatin integrity including DNA fragmentation.

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
Can you tell which image shows polymorphonuclear leukocytes(PMN) and which image shows spermatids? Answer: The left column are PMN leukocytes or white blood cells (WBC). Diff-Quik stain of semen. Magnification 500x brightfield.

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
