Strict Morphology Collection: Spermac Stain
|

| 
Sperm cells are stained using the Spermac stain and Kruger strict criteria morphology performed. The acrosome stains green while the postacrosomal nuclear region is red. Unlike PMN, spermatids are smooth. Fertil Steril 1999;72:124-128. |

The mature sperm cell has a negative "zeta" electropotential after acquiring epididymal proteins and sticks to the surface at the: (1) acrosome tip (2) postacrosome (3) midpiece (4) tailtip or (5) entire surface. Fertil Steril 2006;85:481. |

| 
Acrosomeless human spermatozoa, most of which are round-headed, hence the term round-headed or globozoospermia. These two terms are inaccurate because acrosomeless spermatozoa need not necessarily be round-headed. |

Composite photos of in vitro sperm head decondensation. After sperm entry into the oocyte, the head enlarges (the acrosomal cap is sometimes visible), followed by formation of the pronucleus. Magnification 1000x (Optical 500x, Digital 2x). |

Sperm preparation for ICSI
|
2847 |
4.50 |
| 
This mehod is a rapid and simple sperm preparation for ICSI. This device comprises a tubular conduit, which has a constriction to create capillary flow. Motile sperm, having passed through the constriction, can be observed to maintain a position within the conduit downstream from the constriction means by swimming against the flow of fluid. The device can be used for preparing sperm for ICSI, by harvesting motile sperm from the downstream side of the constriction means using a micropipette. This.. |
