It is a variation of IVF and is applied when the estimated fertilization rates would be very low or nil using conventional IVF. Here are some examples of when ICSI is used: morphology shape of the sperm Low number of sperm in the ejaculate A low number or poor sperm quality. A low number of obtained eggs Interaction problems between the egg and the sperm For the patient, the phases and the procedures are the same as in conventional IVF as for ICSI. The only difference is in the lab work the biologist performs. In conventional IVF, the sperm fertilizes the egg on its own and in ICSI, the biologist selects the most adequate sperm and then injects it into the egg. With the PICSI procedure intelligent hyaluronic acid hydrogel method , we are able to determine sperm selection in the same way that happens in human biology.

Micromanipulation equipment is also used, allowing us to stabilize the egg softly and subsequently place the sperm inside it. In Vitro Fertilisation IVF Because of the risks to the babies of multiple pregnancy, many experts recommend that you limit the number inyeccon embryos transferred. Benjamin Bartoov 25 Estimated H-index: Do you need help?
Some of the injections can be rather painful. What is intracytoplasmic sperm injection? From the way they evolve we propose either short cultures days or long cultures days: ICSI is an effective treatment for sperm-related infertility but it may have genetic risks. Previous exaggerated ovarian response that should be avoided.
One of the most innovative techniques in the field of human reproduction is intracytoplasmic sperm injection, where, with important safety inyecciob high technology measures, a pregnancy is achieved from the implantation of the fertilized ovum in the uterus of the woman. If you and your doctor are concerned about the possibility of passing on a genetic disorder to your childtalk to your doctor about testing the embryo before it is transferred to the mother.
Embryos are then transferred in order to facilitate implantation. It is carried out with the help of an abdominal ultrasound in order to find the perfect spot for implantation. On the whole, patients can return to their daily routine the day after ova extraction or transfer. This includes transfer of fresh embryos and a possible transfer of cryopreserved embryos when the objective is not achieved in the first transfer. The goal is to move the embryo from the laboratory to its final destination for development: In general, during a longer culture period, there are fewer viable embryos but they are of much better quality than the embryos achieved during a short culture period.

After this incubation period, the eggs that have been successfully fertilized and have had 3 to 5 days to further develop further are selected.
Sperm capacitation At the same time, the semen is activated to improve its fertilisation potential. These mature eggs are collected 34 to 36 hours later. Who is this treatment conceived for? People who have a chromosomal problem can seek genetic counselling to learn about their chance of having a child with birth defects. Response is monitored using vaginal ultrasound scans and timely blood analyses: Study and preparation of the patients Every patient is a unique individual.
This technique is used in fertilization when sperm suffers from low count, an abnormal morphology, poor motility or when the sperm is unable to fertilize through IVF.
Your doctor will recommend a certain number of embryos based on your age and other factors such as general health and fitness. Related Articles.
