IN VITRO FERTILIZATION(IVF)
Recently, the amount of couples who apply for assisting fertilization technique is increasing. Due to rising awareness, the easy access to the right information and technical improvements, many couples can overcome their infertility.
IVF is the treatment method that increases the pregnancy chance in couples with non or little pregnancy possibility. It is the impregnation process of man and woman reproductive cells outside body that.
Generally IVF includes a treatment program to be followed step by step.
Pre Interview Phase
The first phase of IVF treatment starts with pre interviewing. Story is recorded in both man and woman’s side once the infertile couple comes for the pre interview. Pre made tests, uterus film, operation epicrisis are evaluated. At the end of the gynecological and urological examinations in light of these, the treatment to be applied to the couple is decided.
Ovulation Induction Period
IVF treatment starts to be applied on the second or third day of the menstruation. Follicle Stimulating Hormone (FSH) medications are administered via injection to induce the oosit. Patient’s oosit induction is evaluated after the injections, by inviting for control.
The last injection (cracking needle) for the oosit maturation is administered on a specific hour. This hour is highly important, because picking up the oosit is performed 35-36 hours after the administration of this injection.
Ovulation induction period ends with this last injection. Generally this period that is completed within 10-12 days is an important phase to acquire a quality oosit.
Oosit Pick Up Process
Picking up the oosit that is induced via the maturation injection; OPU (Oosit Pick Up) process is performed under general anesthesia and lasts about 15 minutes.
While the woman is applied with OPU process, man’s sperm cell sample is taken.
Patient is discharged after the process with approximately 2 hours of resting at the hospital.
This process is the transplantation of the sperm into the oosit under a special microscope via a thin-as-hair needle. The fertilized ootis is called an embryo after this micro-injection process.
If the oosits used in the micro injection process are quality and mature, the fertilization occurs with the average ratio of 80%.
Fertilized embryos are followed up in a special system called incubator.
The transfer day is decided after 2-5 days following the embryo incubation of the existing embryo amount.
Lab-created embryos are transferred into the natural environment, meaning the uterus, and this process is called “embryo transfer”.
Transfer process is no different than a simple examination. No anesthesia is needed.
The process is realized via abdominal ultrasonography.
For the uterus to be visible on the ultrasound screen, the urinary bladder must be full. Before this process the patient is given a high amount of water for full bladder.
Expectant mother is taken to the gynecological examination couch and a speculum is placed on the vagina for the cervical view. Later embryos are placed into to uterus via catheter through the cervical canal and the operation is terminated.
Pregnancy-asisstant Treatment Period (Luteal Phase)
Medication is given for the embryos to hang onto in this phase. Progesterone, estrogen and/or HCG hormone, aspirin derivative medications and injections can be used to dilute the blood in some special cases. This phase lasts 12 days.
It is possible to find out the result of the IVF treatment 14 days after the transfer with a pregnancy test.
