Some ladies select to freeze their eggs, additionally referred to as egg cryopreservation, to delay having youngsters or when a illness has broken their ovaries. Walter says this course of is just like in vitro fertilization (IVF) remedy for infertility. It begins with taking hormone medicines that stimulate the ovaries to develop and produce a number of eggs (that is referred to as ovarian stimulation). As soon as the eggs have matured, the physician removes them throughout an outpatient process. The eggs are saved in liquid nitrogen tanks till you might be able to conceive.
The hormones used for ovarian stimulation could cause unwanted effects like temper swings, scorching flashes, complications, and nausea, however they’re normally gentle. Some folks expertise cramps, bloating, and bleeding after the egg retrieval process.

Gathering the sperm is comparatively simple. The fertility clinic will present a particular container to masturbate into. They’re going to deal with the semen with a particular chemical to guard it from the chilly temperatures, after which retailer it in a tank containing liquid nitrogen.
There is not any threat concerned with accumulating the semen pattern. However generally sperm can grow to be broken in the course of the freezing course of.
Embryo Freezing
The method of freezing embryos is similar to egg freezing. First, the eggs are faraway from the ovaries. Then they’re fertilized with sperm from a accomplice or donor to supply embryos. Lastly, the embryos are frozen. They are often thawed later and transferred into the uterus.
Whether or not to freeze eggs or sperm, or to create embryos after which freeze them, is dependent upon the state of affairs and family-building objectives. “You probably have a person who’s in a long-term relationship or who’s anticipating beginning a household very quickly and has a accomplice or is planning to make use of donor sperm, it may be extra easy to freeze embryos,” says Walter.
Embryos might be broken in the course of the freezing course of. Typically a transplanted embryo would not lead to a being pregnant. And when a couple of embryo is implanted within the uterus, it might lead to a a number of being pregnant.
Ovarian or Testicular Tissue Freezing
“It is a extra superior method, sometimes reserved for prepubescent sufferers or those that want to start most cancers remedy urgently,” says Lin. A part of the ovary containing immature eggs is eliminated throughout a surgical process. The tissue is then frozen till most cancers remedy is completed and the individual is able to begin a household.
The ovarian tissue is reimplanted later, with the hope that it’s going to begin to produce eggs or hormones and restore fertility. Transplanting ovarian tissue leads to a being pregnant about one-third of the time.
Testicular tissue freezing continues to be experimental. It isn’t clear whether or not sperm will develop as soon as the tissue is unfrozen, as a result of the know-how is so new.
Ovarian and testicular tissue harvesting carry the identical dangers as different surgical procedures which might be carried out with anesthesia. In individuals who have most cancers, there’s a threat that implanting the thawed ovarian tissue would possibly reintroduce most cancers cells.
Testicular tissue harvesting might depart the affected testicle barely smaller.
Ovarian Transposition
This minimally invasive process, additionally referred to as oophoropexy, might be an possibility for ladies who get radiation remedy to their pelvis (for instance, to deal with a gastrointestinal or pelvic most cancers) and wish to protect their fertility. The surgeon separates the ovaries and generally the fallopian tubes from the uterus and strikes them exterior of the radiation area to scale back the danger of harm.
As a result of the ovaries cannot be reattached sooner or later, and the uterus could also be broken or made rigid by the radiation, it most likely will not be doable to conceive naturally or develop a fetus to time period. Individuals who have ovarian transposition will probably want to make use of IVF and a gestational provider (surrogate).
