Infertility is a problem that has been increasing over the years due to various factors such as the delay of the time of motherhood for professional reasons, stress, pollution, pesticides, radiation, the use of drugs ...
This, in turn, has made assisted reproduction one of the most avant-garde branches of medicine and one that has made the greatest advances in recent years.
The main key is to make a correct diagnosis of both members of the same and thus offer our patients the most appropriate treatment for your case. This is why, in CREA, we have excelled in the analysis of the male factor that has been so often forgotten despite being responsible for a large number of cases of infertility and those of mixed causes.
Nowadays, a couple that after a year of regular sexual intercourse has not achieved pregnancy, should consult with a specialist to find out the possible cause. Once the diagnosis is made, the simplest effective treatment is indicated, which in milder cases will not need the use of Assisted Reproduction Techniques (ART).. In the cases where it is necessary, the appropriate TRA will be applied, which will be more complex as the gametes of the couple (ovules and spermatozoa) are more altered.
Assisted reproduction treatments
Intrauterine Artificial Insemination:
After controlled stimulation of the ovaries, sperm are prepared in the laboratory and introduced into the uterus at the time of ovulation. It can be with sperm from the couple or from an anonymous donor if necessary.
In Vitro Fertilization (IVF):
After the stimulation of the ovaries to get a greater number of ovules that allow greater opportunities to achieve pregnancy, these are extracted and are inseminated in the laboratory with the sperm of your partner or a donor. At 72 hours post-fertilization, the embryos are transferred to the uterus and / or vitrified for later attempts.
Sperm microinjection (ICSI):
It is a complementary process to IVF and involves the introduction of a previously selected sperm, inside the ovum. It is done in cases in which there is a low sperm count and / or quality, a previous failure of fertilization and in certain cases of low oocyte quality.
Consists in the cryopreservation of embryos that are not transferred to the uterus. This allows us to use them in the future, either for a second pregnancy, or in a second attempt when the first one has failed, thus avoiding having to carry out the treatment from the beginning, since the embryos are already present.
Vitrification of oocytes:
It consists of the cryopreservation of the ovules in cases in which the patient must postpone motherhood due to major causes. It is used as a means to preserve fertility in cancer cases, prior to its chemotherapy treatment. Also for cases in which the woman does not want to give up her motherhood but due to personal circumstances she can not make it come true at that moment, and she takes advantage of vitrifying her ovules when they are young and therefore of better quality and with greater potential for implantation.
Preimplantation Genetic Diagnosis (PGD):
In cases where the parents are carriers of a genetic disease, it is done to identify and select the embryos that are not carriers of it, preventing it from being transmitted to the children. In cases of repeat abortions, advanced maternal age or background that recommends it, the DGP of aneuploidy screening for 24 chromosomes is indicated.
CLOTHING (Receiving the Couple's Ovules):
It is done in the cases of lesbian couples in which both want to participate in the common reproductive project of having their children. One of them provides the ovules that are fertilized with donor semen; and the obtained embryos are transferred to the uterus of their partner.
Egg donation program:
For patients who, due to ovarian problems, can not remain pregnant with their own ovules and must resort to donated ovules by healthy and young women, who comply with all the requirements indicated by the Law, are previously analyzed and carefully controlled from the medical point of view.
Semen donation program:
For cases in which the semen of the couple can not be used, as well as in the case of a woman alone or without a male partner. The donors are previously examined fulfilling all the requirements indicated by the Law.
Department of Andrology
Complete analysis of the male factor to make a correct diagnosis prior to RA treatment. The treatments vary from pharmacological therapy to aspiration of testicular sperm, selection of sperm with intact DNA, treatment of varicocele and prostatitis, as well as surgery in cases of previous vasectomy.
