Survival of Human Spermatozoa after Freezing with Different Techniques

  • Jan Friberg


In comparison with the extensive use of frozen semen in veterinary medicine, farily slow progress in the cryopreservation of human semen has been seen over the past ten years. The primary reason for this is probably the reduced conception rate that is being observed with frozen semen in comparison with fresh semen.1,3 There is also some evidence that certain women cannot conceive with frozen-thawed semen whereas they easily conceive with fresh semen. These disadvantages have called for continued investigation in order to improve the techniques for freezing of human spermatozoa.
