In patients suffering from obstructive azoospermia, sperms can be obtained directly from the testes by doing an epididymal sperm aspiration or biopsy and the sperms can be used for fertilizing the oocytes. The biopsy material can also be preserved in liquid nitrogen for subsequent use.
Firm Hospitals boasts facilities for conducting testicular biopsy and semen banking for such patients. We generally take 3-4 biopsy samples and preserve them in liquid nitrogen for long term storage. This means that patients can undergo ICSI, a second time if they want to have a second child.
Assisted hatching is performed at Firm Hospitals, wherein a hole is made in zonapellucida of the embryo using laser.
Sometimes when you undergo an IVF/ ICSI treatment, more than the required number of embryos will be produced. The excess embryos can be preserved in liquid nitrogen for long periods. Such embryos can be used for future transfer either to have another child or if the cycle fails for any reasons. These Cryopreserved embryos can be conveniently utilized without any hyper stimulation again. Therefore, embryo Cryopreservation reduces the cost of treatment and it can be used as and when required.
But one must know that all the Cryopreserved embryos cannot be preserved with life. Pregnancy can be achieved only with embryos with life. However, it is a convenient procedure for the patients who get more oocytes (more than required for a single transfer).
