Our clinic uses cryopreservation to freeze embryos, sperm, and eggs for later useThis can be especially helpful for women who plan to have children at an older age, or when one member of the couple faces a fertility-threatening illness. Embryonic freezing is a modified form of IVF. For cryopreservation, once the sperm fertilizes the eggs, we allow the embryos to develop for several days.We then place the embryos in our specially designed facilities, where they are frozen for future use (rather than being placed back inside the woman's uterus immediately). When a woman decides to become pregnant, she returns to our clinic and the embryos are then reinserted into her uterus. The pregnancy success rate per frozen embryo stands at roughly 30%, slightly lower than with normal IVF. Sperm freezing is often an excellent choice for men who have to undergo chemotherapy and want to have their own children later in life.The man supplies a sperm sample that is frozen and placed into our clinic's specially designed facilities. This procedure may also be ideal for men who have little sperm in their ejaculate and wish to undergo an operation to extract sperm for future use. The sperm are collected through sperm aspiration. During this procedure, sperm are retrieved from either the epididymis (the tubule that connects the testis to the vas deferens) or the testicles. In many cases, a small number of sperm can be found in these locations and successfully extracted. To achieve fertilization, the woman's eggs are extracted and the sperm and egg are placed together in the laboratory. Intra-cytoplasmic Sperm Injection (ICSI) often provides the greatest chance for pregnancy. Egg freezing is ideal for women with serious illness, cancer, or for those who are unable to undergo the IVF process. The process may also benefit women who wish to have children later in life. |
