Sperm Penetration Tests - Kaiser Permanente
网页2023年11月27日 · Sperm penetration tests check to see if sperm can move through cervical mucus or join with (fertilize) an egg. These tests may be done when you're having trouble getting pregnant (infertility). There are different sperm penetration tests.
Male Fertility Testing: Diagnostic | University of Utah Health
网页The hamster egg penetration test (HEPT) (also known as the sperm penetration assay) is the most accurate test that predicts whether your sperm will be able to fertilize an egg. It can also predict whether lab techniques can improve your sperm’s ability to …
The Sperm Penetration Assay for the Assessment of Fertilization ...
网页The sperm penetration assay, or zona-free hamster oocyte penetration assay is utilized to measure the ability of sperm to undergo capacitation, fuse with the egg membrane and decondense the sperm head within the cytoplasm of the oocyte resulting in the formation of the male pronucleus.

6 - The sperm penetration assay - Cambridge University Press
网页The sperm penetration assay (SPA) or zona-free hamster egg test is one such test which is designed to evaluate sperm functional competence or fertilizing potential. It is based on the phenomenon that a hamster egg, when rendered zona-free by proteolytic digestion of the zona pellucida, can be penetrated by spermatozoa from another species, such ...
Different approaches for assessing sperm function - PMC
网页2020年5月22日 · The use of microscopy, and particularly fluorescent microscopy, could be a very useful tool to assess different parameters in sperm cells both by fluorophores that give indication of a determined function, and by immunolocalization of proteins, that permits the discover of new features or to explain particular sperm functions.
Spermatozoon Penetration - an overview | ScienceDirect Topics
网页Sperm Penetration Assay (Zona-free Hamster Oocyte Test) Removal of the species-specific zona pellucida from hamster oocytes allows multiple spermatozoa from a different species to fertilize one oocyte. This process requires sperm capacitation including the acrosome reaction, fusion with the oolemma, and incorporation of sperm into the oocyte.
Chapter 13 - Oolemma Binding: Sperm Penetration Assay
网页While the cornerstone of the evaluation of male infertility remains the basic semen analysis, the sperm penetration assay (SPA) is a useful laboratory test for predicting the capacity of an individual male’s spermatozoa to fertilize a female oocyte.
Spermatozoon Penetration - an overview | ScienceDirect Topics
网页The sperm penetration assay (SPA) measures the fertilization potential of the sperm. This in vitro test, performed with hamster oocytes that have had their zona pellucida enzymatically removed, enables interspecies generation of the sperm into the oocyte.
