美孕 • 卵子储存
After the eggs are retrieved, they can be fertilized (IVF) to create an embryo. Or they can be frozen and stored for future use. Eggs are frozen primarily in two circumstances.For preserving fertility in women who need egg-damaging chemotherapy or radiation therapy for cancer or.It can also be used in women who wish to delay childbearing because of their careers, or because they have not found a life partner.
As a woman gets older, it is more difficult to get pregnant, more likely that she will miscarry and the risk of having a child with a birth defect also increases. Simply put, the frozen eggs will allow the woman the chance she would had to deliver a healthy child at the time when she freezes them and the eggs can be thawed 5, 10 or probably even 15years later.
Women needing egg freezing will be stimulated in the same manner as for regular IVF. This involved about 10-14 days of treatment with a pill followed by 8-12 days of treatment with a medication that has to be taken as an injection. Side effects are usually only bloating and some light cramping.
Once the eggs are frozen, the doctor will meet and speak with you and advise you as to the quality of the frozen eggs and the chance of pregnancy. It is important to understand that the eggs should have a near identical chance of helping the woman conceive if they are thawed and used a month or decade later.
