What is the natural cycle IVF?
The natural cycle in vitro fertilization (IVF) uses the natural rhythms of the fertility of the body to determine the best time to implant a fertilized egg into the womb. This method can be more convenient for some women because it avoids the use of fertility hormones such as clomifen, which may have difficult side effects. The natural cycle of IVF is cheaper than the use of IVF conventional drugs and brings a significantly less chance of introducing multiples, but the rate of success is lower. This option works best for women who have regular and predictable menstrual cycles.
The first step in the natural process of IVF is to monitor the menstrual cycle. This can be done using a fertility calendar or fertility software to predict days when a woman has the greatest chance of conception. Women using this method should monitor their daily basal temperatures to help predict. The woman reaches the height of her fertility at the point of her menstrual cycle when he reacts to Luten's hormone peak. NearThe fertility of fertility is explored by a obstetrician or fertility specialist to ensure that eggs in her ovaries ripen correctly. As the ovulation approaches, a woman can undergo daily ultrasonic procedures to detect the production of viable mature eggs. If the eggs do not develop, the doctor may administer hormone stimulating follicles (FSH) or human chorionic gonadotropin (HCG) to support production.
The woman undergoes the harvest of eggs as soon as the fertility specialist identifies mature eggs. Unlike IFV, when using drugs such as Klomifen, only one egg for treatment reaps fertility specialist. Eggs are usually removed from the ovaries in the office procedure using a conscious sedation. The harvesting procedure is facilitated by a transvaginal ultrasound, which is helped by doctors Loced's mature eggs.
In addition to the timing of egg collection and implantation, the natural cycle IVF uses processes similar to conventional IVF. will be fertilized after harvesting eggs. If the egg develops on a viable embryo, it will be placed in the uterus of female growth. A pregnancy test carried out two weeks after the egg is transferred to the womb, determines whether the procedure was successful.
Fertility clinics claim about 35% success after transmission of embryos with natural IVF procedures. This does not take into account patients who do not develop viable eggs during treatment or for eggs that cannot insemination. Some scientists suggest that the actual rate of delivery - taking into account patients falling out of the program, spontaneous abortion and other factors - has about half the success of traditional IVF.
One of the limitation of the natural cycle IVF is that implantation of only one fertilization egg results in only one chance of treatment. This reduces the risk of more implantation, but may also increase the number of treatment necessary to achieve pregnancy. Conventional IVF procedures can harvest many eggs at once that can be frozen and implanted lateri. Women who chose the natural cycle IVF will have to complete the entire harvesting procedure every time they want to try to conceive.
