In cases of severe male factor infertility, before performing in vitro fertilization with intracytoplasmic sperm injection (ICSI), it is important to study testicular meiosis to rule out genetic abnormalities in sperm that could lead to repeated pregnancy failures or embryonic abnormalities. In some cases, if there is a sufficient number of spermatogenesis cells, this study can be performed on semen.
No, before any treatment it is absolutely essential to perform a biopsy to confirm the diagnosis, to know with the greatest precision the degree of the lesion that the patient suffers and in this way to individualize the treatment and achieve the best healing results.
There is no specific test to detect endometriosis, but it can be suspected through symptoms and a physical examination. In some cases, an imaging test (ultrasound or MRI) may be helpful.
The only way to know for sure if you have endometriosis is to remove endometrial tissue through surgery and analyze it.
The medical team selects the donor who most closely resembles the patient or couple physically, and is compatible in blood type.
Sentinel lymph node localization is performed using a liquid labeled with isotopes (Technetium-99), which is injected around or into the tumor. A bone scan is then performed to pinpoint the exact location. The following day, the tumor and the sentinel lymph node are removed, and the node is immediately analyzed by cytology. Subsequently, the appropriate diagnostic workup is carried out.
The semen undergoes a capacitation process in the laboratory, where the highest-quality sperm are selected and non-viable ones are removed. This process increases the chances of success by using only the most motile sperm.
The recipient's uterus is prepared through hormonal treatment that simulates the natural menstrual cycle, preparing the endometrium for embryo implantation. This treatment may include the use of estrogen and progesterone.
The endometrium is the inner lining of the uterus. Endometrial cancer typically manifests in the following ways:
A presumptive diagnosis is made using gynecological ultrasound and hysteroscopy. A definitive diagnosis is made by an endometrial biopsy, which can be performed during the same appointment with minimal discomfort for the patient.
A semen sample is obtained by masturbation at the clinic, which is analyzed in the laboratory within 30-60 minutes.
Ovarian stimulation is carried out through the administration of hormonal medication that helps the ovaries produce more than one egg in a cycle. This increases the chances of success in artificial insemination.
Ovarian stimulation is a crucial stage in IVF, where hormonal medications are used to stimulate the ovaries to produce multiple eggs in a single cycle. This process increases the chances of success by providing several eggs to fertilize.
In vitro fertilization (IVF) takes place in a laboratory where collected eggs are combined with sperm. At Institut Marquès, this is done using intracytoplasmic sperm injection (ICSI), a process in which a single sperm is injected directly into an egg.
The IVF process with egg donation begins with ovarian stimulation of the donor to collect the eggs. These eggs are fertilized in the laboratory with sperm from the partner or a donor. The resulting embryos are cultured for a few days and then transferred to the recipient's uterus.
To maximize the chances of success, it is important to synchronize the menstrual cycles of the donor and recipient. This is achieved through the administration of hormonal medications, which prepare the recipient's uterus to receive the embryos at the appropriate time.
The eggs are fertilized by in vitro fertilization, and the sperm are used in artificial insemination or IVF, as the case may be.
Depending on the case, it is used in artificial insemination, IVF or ICSI.
In cases of deep endometriosis, several organs such as the intestines and urinary tract may be affected. This can cause various symptoms such as pelvic pain, pain during bowel movements, and others. Surgery for endometriosis can be complex in these cases, and therefore, the risk of complications is higher. If endometriosis is very severe, it can affect nearby organs and cause serious kidney and intestinal problems.
The most significant advance in recent years is that surgical indications have become increasingly limited. This helps preserve ovarian function and fertility in patients affected by the disease, since surgery greatly impacts ovarian reserve.
There is still a long way to go to fully understand this disease and thereby improve its treatment and prognosis.
The main difference lies in the origin of the eggs. In conventional IVF, the woman's own eggs are used, while in IVF with egg donation, the eggs come from a donor. This approach is used when the woman cannot produce viable eggs.
The main advantages of egg vitrification include fertility preservation, the possibility of planning a future pregnancy without age affecting egg quality, and the flexibility to use frozen eggs when the time is right.
The first signs of a successful transfer may include light bleeding, abdominal bloating, and breast tenderness. However, definitive confirmation is only obtained through a pregnancy test approximately 10-12 days after the transfer.
If pregnancy has not been achieved after one year of unprotected intercourse, or if there is a medical history or known abnormalities.
The best time to freeze eggs is before age 35, when egg quality and quantity are optimal. However, every woman is different, and it's recommended to consult a fertility specialist to determine the best time for your individual circumstances.

It is recommended to perform it both before and after, as it helps prepare the endometrium and reduce anxiety.
At any time, especially if you feel sadness, frustration, or fear that interferes with your well-being.
Embryo transfer is generally performed between 3 and 5 days after fertilization, when the embryos have reached the blastocyst stage. This allows for the selection of embryos with the highest implantation potential.
The cost of PGT is in addition to IVF treatment and varies depending on the clinic and the type of test performed (PGT-A, PGT-M, PGT-SR). Generally, the cost can range from €2,000 to €5,000, depending on the number of embryos analyzed and the complexity of the genetic analysis.
The cost of an IVF cycle can vary considerably depending on the clinic and country, but it generally ranges from €4,000 to €10,000. This cost includes, among other things, the egg retrieval, fertilization in the laboratory, and embryo transfer, although additional costs may apply for services such as embryo cryopreservation.
The cost of IVF with egg donation is generally higher than that of conventional IVF due to the costs associated with egg donation, such as donor compensation, medical tests, and the cryopreservation process. Prices can range from €6,000 to €13,000 per cycle, depending on what is included in the treatment package.

The cost of artificial insemination can vary depending on the clinic and the country, but it generally ranges from 600 to 2,000 euros per cycle. This cost may include medical consultations, ultrasounds, and the insemination procedure itself.
The cost of egg vitrification varies depending on the clinic and country, but generally ranges from €1,000 to €3,000 per cycle. This cost includes ovarian stimulation, egg retrieval, and the freezing process. There are also additional costs for annual egg storage.
The number of embryos to be analyzed depends on the number of embryos available and the couple's preference. It is common to analyze all available embryos to select those that are genetically normal.
The number of embryos to transfer depends on several factors, including the woman's age and the quality of the embryos. At Institut Marquès, we transfer a single embryo in over 90% of cases. This demonstrates that the chances of success do not decrease, thus avoiding the risks associated with multiple pregnancies.

Normally between 2 and 6 mature eggs.
Between 2 and 5 days.
Ovarian stimulation typically lasts about 10 days, depending on the ovaries' response to the medication. During this time, ultrasound scans and blood tests are performed to adjust the medication dosage and schedule the egg retrieval.
Vitrified eggs can remain frozen for many years without losing their viability. There is no specific time limit, giving women the flexibility to decide when they wish to use them.
Embryos can be frozen and stored for several years without losing their viability. The decision of when to use these embryos depends on the couple's reproductive plans.
PGT results are usually available 7 to 14 days after the biopsy. This allows specialists to determine which embryos are genetically normal and can be transferred to the uterus in a subsequent IVF cycle.
Most tests can be performed in one or two menstrual cycles.
Rehabilitation is a very important part of breast cancer treatment to help women return to normal activity as soon as possible and prevent movement restrictions. Recovery will vary from woman to woman, depending on the extent of the disease, the treatment received, and other factors.
Both options are valid. The psychologist can work with you individually or with your partner.

The ultrasound and hormone tests are painless. The hysterosalpingography may cause mild discomfort, similar to menstrual cramps.
For many years. Studies show that semen maintains its viability after decades of storage.
Indefinitely. The law in Spain allows its storage with the consent of the partner or patient.
Not directly, but it can increase adherence to treatment and improve quality of life, which positively influences the process.
Yes, all information and results are handled with maximum confidentiality.
It is not 100% guaranteed, but it significantly reduces the risk of transmitting hereditary diseases.
On the contrary, it allows the transfer of a single, top-quality embryo, thus reducing the risk of multiple pregnancy.
Yes, factors such as tobacco, alcohol, being overweight, or stress influence sperm quality.

Yes, factors such as tobacco, alcohol, being overweight, obesity, or stress can significantly affect male fertility.
Intense stress can affect the regulation of cortisol and catecholamines, and could decrease the oxygen supply to the fetus, causing growth retardation. But it is NOT a cause of miscarriage.
Ovarian puncture is a minimally invasive procedure performed under sedation to retrieve eggs from ovarian follicles. Using a fine needle guided by ultrasound, the eggs are collected and prepared for fertilization in the laboratory.
All cancers are serious, but endometrial cancer allows for very effective treatments when diagnosed in its early stages. Treatment is based on surgery and, generally, radiotherapy followed by other therapies.
No, it is performed in the same consultation and local anesthesia is rarely required.
IVF itself is generally not painful, although some procedures, such as egg retrieval and hormone injections, can cause temporary discomfort. Patients often describe these symptoms as similar to those of premenstrual syndrome.
IVF offers multiple advantages, including the possibility of overcoming fertility problems in both men and women, the option of selecting higher quality embryos, and the ability to perform pre-implantation genetic testing to detect possible hereditary diseases.
Embryo transfer is generally performed between 3 and 5 days after fertilization, when the embryos have reached the blastocyst stage. This allows for the selection of embryos with the highest implantation potential.
