FERTILIZATION TECHNIQUE:
Conventional In Vitro Fertilisation and ICSI IVF
The in vitro Fertilization and technique ICSI with high success rate in male infertility. It allows the direct union of the egg and sperm.
Fertilization Technique
WHAT DOES CONVENTIONAL IN VITRO FERTILIZATION MEAN?
In a conventional in vitro fertilization, the eggs and the sperm previously treated are placed in the same environment and space with the intention that the gametes themselves carry out the fertilization spontaneously as would happen in the fallopian tubes. An essential condition for carrying out this technique is a minimum concentration of spermatozoa with good mobility of 80,000 spermatozoa per milliliter and per ovum to be fertilized.

In Vitro Fertilization Technique
WHAT IS A FIV ICSI?
(INTRACYTOPLASMIC SPERM INJECTION)
It is one of the existing fertilization techniques and it is highly used in the IVF treatments due to its great capacity to fertilize. It consists of directly introducing a spermatozoon into a mature egg by means of micromanipulation tools.
This technique was born with the objective of treating very severe cases of male sterility, and since its origin, in 1992, it has allowed many men to become parents, who otherwise would not have been able to fulfill their dream.
The Intracytoplasmic Sperm Injection even allows the use of sperm from the epididymis or testicle (obtained by aspiration or testicular biopsy in cases where there are no sperm in the ejaculate being these mostly immobile TESE/TESA.
IN WHICH CASES IS FIV ICSI INDICATED?
ICSI allows us to achieve pregnancy in very low quality sperm samples, since only one motile sperm is needed for each mature egg.
- Men with a low sperm count, low motility or poor sperm morphology.
- Limited cryopreserved semen samples following a vasectomy, testicular biopsy or after chemo or radiotherapy treatment.
- Difficulties in obtaining an ejaculation under normal conditions.
- Need to use FERTILE as a sperm selection technique.
- Other factors such as several cycles of IVF or negative artificial insemination, low number of eggs in the follicular puncture or Pre-implantation Genetic Diagnosis techniques.
ICSI IVF PROCESS
In Vitro Fertilization ICSI
ICSI PROCESS
The technique is carried out in an inverted microscope, equipped with a state-of-the-art micromanipulator system that allows high-precision movements through micropipettes. The embryologist will be in charge of selecting, one by one, those spermatozoa with the best morphology and mobility to introduce each of the mature eggs available in each case. Once the sperm has been selected, the egg will be held with a micropipette, called a Holding, and the sperm will be introduced into the egg with the ICSI micropipette. Once a spermatozoon has been introduced into each egg, it will be necessary to wait a few hours to assess whether fertilization has taken place correctly. The microinjected eggs are placed in the Embryoscope to give them the optimal culture conditions necessary for their development and maintenance.
Comparison
DIFFERENCES BETWEEN CONVENTIONAL FERTILIZATION AND ICSI
The two techniques achieve the same objective, the fertilisation of an egg to turn it into an embryo thanks to the entry of the sperm into the egg, although the process for achieving this is a little different and the requirements to be able to do one technique or the other are also different. While in a conventional IVF, about 80,000 sperm are needed to fertilise the egg, in ICSI only one motile sperm is needed from a semen sample or even from a testicular biopsy.
