There is no single path to building a family. If you are facing difficulties conceiving through conventional means, fertilization is our specialty. Through advanced methods such as in vitro fertilization and egg/sperm donation, we overcome barriers that may seem limiting. Every person has the right to experience the joy of creating life, regardless of any obstacles that may arise.

Infertility is the delay or difficulty a couple faces when trying to conceive. For women under 35, we consider infertility after 1 year of trying; above 35, it is important to investigate after 6 months of unsuccessful attempts.

Infertility can originate from problems in the female partner, the male partner, or both. Therefore, it is always important to investigate the couple. In approximately 10-15 cases, we do not identify any cause (unexplained infertility), despite the difficulty in conceiving.

If you are under 35 and have been trying to conceive for more than a year, or if you are over 35 and have been trying to conceive for six months, it is important to seek help from a human reproduction specialist.

Several tests will be requested, such as hormone level tests, ovarian reserve assessment (by ultrasound or hormone testing), fallopian tube evaluation, and semen analysis. For each case, it may be necessary to investigate other associated conditions, such as endometriosis, polycystic ovaries, and thyroid disorders. Medical evaluation is very important to individualize each investigation.

Yes! There are several types of treatment available to help people who cannot conceive spontaneously. These include ovulation induction, timed intercourse, intrauterine insemination, in vitro fertilization (IVF), and the use of donor eggs or donor sperm. For each case, there is a more suitable treatment.

No! IVF is our greatest ally in many situations. But there are other treatments available, such as ovulation induction, timed intercourse, and intrauterine insemination. It's important to talk to a specialist to find out the most appropriate treatment for your case.

Artificial insemination, also known as intrauterine insemination (IUI), is a technique in which semen is injected into the uterine cavity around the time of ovulation. It is a simple, low-complexity procedure that can be performed in a doctor's office.

Artificial insemination involves injecting a sperm preparation into the uterus, close to the time of ovulation.

In in vitro fertilization, the meeting between the egg and sperm takes place in the laboratory. A few days later, the resulting embryos can be transferred back to the uterus to create a pregnancy.

The risk of having twins after artificial insemination or in vitro fertilization is much lower today compared to the risks in recent decades. The chance of having twins depends on several factors, such as the patient's age, the type of treatment, and the number of embryos transferred to the uterus. But currently, despite the myth, most pregnancies after treatment are not twin pregnancies.

The chance of pregnancy after in vitro fertilization or intrauterine insemination depends on a number of factors. The two most important are age and the number of eggs expected from the procedure (ovarian reserve). Generally speaking, the younger the woman and the better her ovarian reserve, the greater the chances of success.

The cost of treatments depends on a number of factors: the type of treatment, the location where it will be performed, the type and quantity of medications, and other strategies that may be indicated, such as embryo freezing and biopsy. It is best to seek guidance from a specialist in Human Reproduction to receive individualized advice for your specific case.

Egg freezing is a strategy for preserving fertility. As we know, a woman's ovaries have a limited lifespan, and age is the main factor in the decline in egg quality and quantity. Therefore, women who wish to have children but are considering postponing motherhood can freeze their eggs to preserve quality and increase their chances of having a healthy baby in the future. Additionally, patients who will need ovarian surgery or radiation and chemotherapy for cancer treatment can freeze their eggs as a way to preserve fertility during their treatments.

There is no maximum age for freezing eggs. However, we know that age is the main determinant of the quality and quantity of a woman's eggs. Therefore, the earlier one decides to freeze eggs, the greater the chance of having a baby with them in the future.
