FAQ-Frequently asked questions

When to consult a fertility specialist?

It is recommended that if you’re under 35 years old and have been trying for 12 months or more to get pregnant, it’s time to seek the advice of a fertility specialist. This period should be reduced to 6 months if you are over 35 years old, or if there is some reason for you to believe there may be a fertility problem.

Is there a waiting list for the treatments?

No there isn’t, at IMER there are no waiting times to start a treatment. We also commit to planning the treatment on the dates chosen by the patient.

What is the percentage of success?

Each technique has different success rates, these may vary a lot depending on the age of the patient. Some treatments like AI have a 20% chance of success at each trial.

In Vitro Fertilization may reach a 50% rate of success with younger women and oocyte donation ends in pregnancy more than a 60% of times.

What are the different treatmens?

The list of assisted reproduction techniques is long: artificial insemination, In Vitro Fertilization, oocyte donation, preimplantation genetic diagnosis… but not all them are indicated for all couples.

It is essential for the success of a treatment to start with a comprehensive assessment of the causes of infertility. After having diagnosed each case individually, the most adequate treatment, and the one that offers the highest chance of success, will be designed and recommended.

What are the main causes of sterility?

There are many different factors that can cause infertility. It is generally established that 40% of the cases are male related, and 40% female related, the other 20% appears to be a mixed causal factor.

The main male cause is diminished sperm quality or even absence of spermatozoa in the ejaculation, but other causes exist, such as genetic disorders, for example.

For women, the main cause for infertility is advanced maternal age. The role of women in developed societies has changed a lot in the last few years, causing a significant delay in the age at which they start trying to get pregnant. After 35 years of age, there is a decrease in the fertility rates in women, and the decrease is even more significant after 38 years of age. All of this causes an ever-increasing demand of medical assisted reproduction.

What is the difference between sterility and infertility?

Both terms are used indifferently but they refer to different conditions.

We speak about sterility when a couple has not been able to conceive after having had unprotected intercourse for a year or longer.

On the other hand, we speak about infertility when a woman is able to get pregnant but is unable to carry the pregnancy long enough to deliver a baby (i.e. repeated miscarriages, premature delivery…).

How many couples are affected by these conditions?

According to epidemiology studies published so far, around 15% of the couples of reproductive ages have some kind of infertility disorder, and this a growing trend. That is one out of the six couples will need to seek help from a fertility specialist.

When is a couple considered sterile?

We consider that a couple is sterile when after one year of regular sexual intercourse with no contraceptive methods they have not achieved a pregnancy.

This period is approximate and it may vary with age, for example after the age of 35 we recommend to visit the specialist after 6 months of unsuccessful intents.
