Summary

250 petitions for FISH of spermatozoa were requested, determining the total and particular incidence in each of the indications collected. The effect of annexin columns was evaluated in 10 couples with altered FISH. In each of the couples, oocytes were pseudo-randomised to the control group and MACS®. All couples received experimental treatment. Mixed logistic regression model were adjusted to evaluate the effect of MACS® on the response variables studied.

Interventions

DEVICE

Magnetic Activated Cell Sorting

The MACS® ART Annexin V System has been designed for the in vitro elimination of apoptotic human spermatozoa in fresh, cryopreserved or otherwise manipulated semen samples. Samples processed by this technique can be subsequently used in any assisted reproduction procedure. Annexin V recognizes externalized phosphatidylserine (ePS) on the plasma membrane of apoptotic spermatozoa. Depletion of the altered sperm begins with magnetic tagging of the sperm. The system selectively retains unwanted sperm by utilizing the natural ability of annexin V to recognize the ePS on the plasma membrane of the altered sperm, because annexin V is conjugated to metal microspheres. The labeled cells pass through a separation column in a fixed magnetic field. Unwanted (altered) spermatozoa are selectively retained in the separation column. Unlabeled spermatozoa pass through the column where they are collected for later use.
