Voorbeelden van spermatozoon

• Again, this means that it is unlikely for spermatozoa to reach the uterine tube after the arrival of the oocyte.

• Staining procedure to detect viability and the true acrosome reaction in spermatozoa of various species.

• Owing to their lower affinity for the epithelium, spermatozoa that become capacitated are released from the storage site.

• Large numbers of mice established by in vitro fertilization with cryopreserved spermatozoa: implications and applications for genetic resource banks, mutagenesis screens and mouse backcrosses.

• Unprotected freezing of human spermatozoa exerts a detrimental effect on their oocyte activating capacity and chromosome integrity.

• Prolonged exposure to ethanol destroys this ability, but it may be possible to develop simple non-freezing methods to preserve spermatozoa for long periods of time.

• Eggs were put separately into droplets (0.5 xl) of fertilisation medium under paraffin oil and 10-20 capacitated spermatozoa were added.

• We wanted to find out whether such treatment affects the ability of the egg to complete the meiosis and to transform nuclei of spermatozoa.
