- cancer patient undergoing chemotherapy
Procedure:
- Ovarian stimulation

Sperm cryopreservation
- Storing sperm for future use

Procedure:
- Collected sterile container
- Analysis for volume, color, PH, viscosity, sperm motility, sperm count, sperm morphology.

- No need to repeat entire IVF procedure again
- Patient who are not ready for childbearing they can freeze embryo.
- Career oriented women’s can freeze embryo.
