What are in vitro fertilization ivf treatments?
In vitro fertilization (IVF) means creating human embryos outside the body. Fertilization does not interfere with anything in the child’s genetic complex, so between the procreated fetus and the fetus created in vitro differences of naturally development do not occur. After hormonal stimulation of the ovaries, oocytes (female germ cells) are extracted and placed in contact with the partner’s sperm in a test tube (in vitro). The sperm will fertilize oocytes and embryos will be obtained so that will be inserted into the uterus of the mother, where, hopefully, they will continue to grow, resulting the pregnancy. The chances of success of in vitro fertilization procedure (a pregnancy viable) are however quite small percentages estimated around 30-35%.
How ivf procedure is done?
In vitro fertilization IVF procedure consists of three major steps: induction of ovarian stimulation; ovarian puncture (oocyte retrieval); embryo transfer.
- Controlled ovarian stimulation – induce multiple follicular growth: consists of two phases: pre-treatment when ovarian function is temporarily suspended either with contraceptive pills., either with injections. After this pretreatment, if everything is okay, can start ovarian stimulation, usually by different treatment depending on the patient and its hormonal profile. The average length of stimulation is 10-12 days. When the biggest follicles reach 17-18 mm it begins preparation for oocyte retrieval. It follows an injection that triggers the final phase of maturation of oocytes and puncture is scheduled after 36 hours.
- Ovarian puncture: at 36 hours after the injection of hCG (Pregnyl, Ovitrelle) the ovarian puncture procedure is performed under anesthesia. The same day, the oocytes are fertilized either by direct fertilization or (especially in the case of a hypo male fertility)with injection of sperm directly into the oocyte (ICSI). The oocytes may not be retrieved from all follicles, the extraction rate is 80%.
- Embryo transfer: the transfer of one, two or three embryos (rarely four) is scheduled second , third or fifth day after the puncture. During the transfer, a catheter is passed through the cervix to see if the transfer is easy or difficult. Once it is confirmed the access to the uterus, the embryos are absorbed in a similar catheter and transferred into the uterine cavity.
Ivf treatment risks:
There is the possibility of an ectopic pregnancy, after IVF, the risk is 2-3%. It is also possible for a person to develop a pregnancy in the tubes and one in uterus (the risk is 1: 5000 to 1: 30,000). The risk of miscarriage is increased in cases of pregnancy obtained by IVF, which is mainly caused by underlying problems regarding the IVF procedure and not the in vitro fertilization procedure itself .
In vitro fertilization IVF can be very stressful and therefore try to keep stress as low as possible before and during in vitro fertilization. Maintain a healthy lifestyle and healthy eating habits. Couples who have good emotional support from family members, friends, other couples facing infertility have a higher rate of fertility than couples who do not have this type of emotional support. If you are feeling ready to confront with these obstacles then in vitro fertilization is for you.
