At Kamala Fertility, we have the facilities for cryopreservation of sperms, oocytes and embryos. Cryopreservation at sub-zero temperatures (-196 C) gives indefinite longevity to cells without any chemical damage. These have proven successful pregnancy rates. During IF extra sperms, oocytes or embryos are frozen for later use or donation. The success rates with retrieved sperms are the same as other IVF.
