In vitro fertilization, step by step

When from one month to the next, storks are left desirable and the dream is overshadowed by disappointed hopes, couples often have no choice but to turn to procreation aided.

Medically assisted procreation (ART) is a general term for all medial interventions aimed at improving and / or encouraging pregnancy. In vitro fertilization (IVF) is a process that allows fertilized eggs in the laboratory.

These are, in detail, the IVF steps in what is called the “classic” protocol.

Set protocol
The first appointment at the fertility clinic serves to establish the patient’s medical profile. We ask about pregnancy history, miscarriage, abortion, etc., according to which the doctor will determine preconception blood tests. In some cases, before making protocols and prescribing hormonal drugs, ultrasound is needed to establish a patient’s ovarian reserve.

Start injection
We are waiting for the next menstruation. On the first day of menstruation, the patient must contact the clinic and then the nurse tells him when to start hormone injections, always according to the applicable protocol.

RenĂ©e Cardinal, Director of Operations at the Ovo Clinic explained, “In a natural cycle, women only have one egg at a time. In the IVF process, drugs are used to stimulate follicles and increase oocyte counts, with the aim of increasing the chances of success.”

Ultrasonography rotation
After the first injection, ultrasound is performed every two to three days to check the effect of the drug on egg maturation. The quality and size of the follicles are monitored and the injection dose modulated according to the results. Special attention is given to ovarian hyperstimulation (abnormal increase in ovaries), a complication that we want to avoid.

Puncture and removal
In general, around the third ultrasound, the follicle is large enough to be removed and it is at this point that the puncture is done. As much as possible contact with spermatozoa.

“Meanwhile, sperm is collected on the day of the prick, so it is as fresh as possible,” Cardinal said.

Fertilizing in the laboratory
Recovered spermatozoa are put into eggs, hoping to get an embryo. Three to five days later, depending on the gradation, the best of them are transferred to the uterus and what remains is to wait for the implantation to occur.

It is hoped that HCG levels will increase
Two weeks later, a blood test is done to ensure that the level of chorionic gonadotropin (HCG) increases. If so, that’s a good sign, because this hormone is only produced from fertilization.

  1. This design is wicked! You obviously know how to keep a reader
    entertained. Between your wit and your videos, I was almost moved
    to start my own blog (well, almost…HaHa!) Excellent job.
    I really enjoyed what you had to say, and more than that, how you presented
    it. Too cool!
