Females about to go through cancer treatment have a range of alternatives when it comes to fertility preservation. For instance:
Ovarian Tissue Cryopreservation (OTC)
OTC is a process that gives an opportunity to most females (cancer patients) to have children later in life by ejecting and freezing ovarian tissue prior to the initiation of such treatments. In other words, the ovarian tissue can be thawed and re-implanted. This procedure facilitates spontaneous pregnancy as there is a complete restoration of the ovary working. In addition, as the hormone levels return to their standard levels, so the secondary effects associated with early menopause such as heart problems, hot flushes, osteoporosis, can be evaded.
Egg (Oocyte) Freezing
Egg freezing, also referred to as Mature Oocyte Cryopreservation, is a process that saves prospects of a female's pregnancy. In this procedure, the unfertilized egg is frozen, and the fertilization process takes place after the patient’s wish to get pregnant. In a laboratory, the frozen egg is defrosted, mixed with sperm and implanted in the female’s uterus.
In Vitro Maturation (IVM)
In this procedure, the eggs are collected from a female prior to their maturation. In this technique, the eggs go through a maturation process outside the patient’s body in a petridish. It is performed in a laboratory; after the eggs complete their maturation process, they are fertilized and the developing embryo can be transferred in the uterus as it is done in a standard IVF procedure. This procedure is a good alternative when the patient can’t avoid the initiation of cancer treatment and there is negligible time left for carrying out a usual hormonal stimulation for recovering the mature oocytes.
