What is the difference between infertility and sterility?

Sterility may be defined as incapability of getting pregnant have having had sexual intercourse without protection on a regular basis for a period of one year. The term infertility is applicable to couples who become pregnant, but this pregnancy does not progress (repeated abortions). Inn various forums and internet sites, these two terms are used indistinctly.

How can we diagnose infertility?

The man and the woman should be subjected to an evaluation by a reproduction problem specialist. It is recommended to meet a gynecologist specializing in assisted reproduction, because the sterility report includes tests which are not generally carried out by classic gynecologists. Inform us about your case.

What is the cause of infertility?

In approximately one third of the cases, the women suffer from a problem that could lead to infertility, whereas in another one third, this infertility is due to factors or problems concerning the reproduction system of the man. The other third concerns the cases where the problems are presented by both the members of the couple.

Is infertility a common problem? Are there more and more cases of infertility?

Approximately 15-20% of couples have reproduction problems. In Spain, close to 800000 couples suffer from sterility.

The developed countries are experiencing an increase in infertility cases and a decrease in birth. Women are increasingly looking to get pregnant late, when the chances to do so naturally are lower. We are also seeing an increase in male infertility, due to the progressive deterioration of the quality of the sperm, without doubt because of environmental factors such as pollution, pesticides, the use of substances and additives in certain foods which may affect the sperms. Stress and the regular consumption of alcohol, drugs and tobacco also influence the quality of the sperm.

Can I become infertile after having had children?

Infertility problems may occur at any time. The fact of having had children previously does not mean that you will be fertile in the future. Hence, there are more couples suffering from secondary infertility (infertility problems in couples having already had one or more children) than primary infertility (infertility problems in couples that have never had a child).

How to prevent infertility?

In certain cases, losing a little bit of weight, quitting drugs, alcohol or tobacco, following a safe, balance and healthy diet is enough to improve one’s fertility. Moderate and regular physical exercise is also desirable. The American Society of Reproduction Medicine affirms that a high level of stress may lead to spasms in the fallopian tubes and reduce the production of sperm in men. We have all heard about people who have tried getting pregnant for a long time without succeeding were able to do so during holidays or while traveling. However, there are many people who cannot prevent or avoid infertility problems and should, rely on the services of a specialist.

Can we increase our chances of getting pregnant naturally?

In general, if the woman has a regular cycle, the ovulation will happen around the 14th day of the cycle. We also recommend initiating sexual relations from the ninth or tenth day of the cycle (the husband should abstain from all ejaculations for four or five days) and, from this time, have sexual intercourse every alternate day for approximately one week. If the sperm is normal, having sexual intercourse everyday will not affect the prognostic. On the other hand, if the quality or the quantity of sperm is low or too just, having more frequent sexual relations reduces the chances of success.

Can stress affect or reduce my fertility?

We are in fact talking about the relationship between anxiety or stress and a reduction in fertility; but it is difficult to know up to what extent stress may prevent a person from getting pregnant. We however know that infertility produces stress in a couple which can deteriorate the relationship and the quality of life, for which a specific treatment is required.

Under which condition can sexual relations increase the chances of success?

There are many unfounded beliefs and ideas. We know that no specific type of position influences the possibility of getting pregnant, or having achieved an orgasm does not increase the chances of success. Lying down after sexual intercourse to help the ascent of sperms to the uterus does not improve anything either, since this ascent is immediate. Rest is therefore not necessary, nor raising the legs or adopting such a sexual position. Evidently, it does not do anything if the man keeps his organ in the vagina of the woman so that the sperm does not go out, since uterus contractions quickly push the sperms to the uterus, condemning those that can’t fall along the vagina. We however, don’t recommend the woman to take a vaginal shower immediately after sex or to use lubricants that may affect the sperm mobility. The use of tampons does not affect the fertility of the woman, not more than taking the pill or other contraception methods, under the condition that it is done as per its prescribed way.

Is the age important?

Presently, more and more couples want their first pregnancy after the fertile age of the woman. From 35 years onwards, the fertility of the woman is reduced progressively and after 45 years, the possibilities of getting pregnant are exceptional. It seems like the quality of the sperm in the man is reduced only after 50 years, and sometimes they remain fertile up to more than 70 years.

Does infertility require complex treatments?

No, certain couples can improve their fertility by applying simple lifestyle changes. On the other hand, some couples may need minimal medical interventions, a minor surgery, for instance, or initiate a specific medical treatment before being ready and able to conceive a child.

About the assisted reproduction

Is there a waiting list to have an assisted reproduction treatment?

The waiting list is currently 7 days for a first consultation. If the diagnosis is clear, the treatments can start immediately. We can plan these treatments in our assisted reproduction centers at the time that it suits you best. If you are a receiver of oocytes, there is no waiting list in our oocyte donation plan.

What are our chances of success?

The fertilization and pregnancy possibilities after applying a treatment depend on the conditions of each couple (age of the woman, quality of the sperm, presence of endometriosis, etc.) and the used assisted reproduction treatment.

What are the risks associated to the use of an assisted reproduction treatment?

  • Artificial insemination:
    The most important risk is multiple pregnancies. The ultrasound control during the treatment generally prevents this possibility.
  • In vitro fertilization:
    By removing the general anesthesia in most cases, the complication risks are very low. Even if the hormonal treatment is without risk, the main problem resides in a possible ovary hyper-stimulation syndrome due to the hormonal treatment. The percentage of cases is weak and your gynecologist will inform you about the controls in case a risk is present or not.
  • Multiple pregnancies:
    With regard to the In Vitro Fertilization, if we transfer 3 embryos, the percentage of twins is 20% and tripled by 4%. If such an eventuality is not foreseeable, we can voluntarily reduce the number of embryos to transfer, at the risk of reducing the changes of success.

What are the main assisted human reproduction treatments?

The main assisted reproductive treatments are artificial insemination or intra-uterus and in vitro fertilization. For the in vitro fertilization, we use the technical ICSI (intracytoplasmatic injection of sperms), to which we can add the IMSI technique (the sperms are morphologically selected by a 40 x better observation than the conventional ICSI) in our laboratory.

What is the difference between artificial insemination and in vitro fertilization? What’s the best option?

They are distinct techniques that are prescribed depending on the case. Artificial insemination is simpler, because it consists of depositing the sperms improved in the laboratory in the uterus of the woman at the time of ovulation. The hormonal stimulation is very light and lasts only approximately 7-10 days.

The in vitro fertilization is more complex, because it requires a more important hormonal stimulation to proceed to the insertion of ovaries (in the operating block and under sedation), to extract the oocytes that will be fertilized in the laboratory by sperms. After 2 to 5 days of development in the special incubators, the embryos are placed in the uterus and a normal pregnancy will be experienced. The entire procedure lasts approximately 20-25 days.

more info +

Are these assisted reproductive treatments painful?

These techniques are not particularly painful. If an ovary insertion is required (during the In Vitro fertilization) in order to extract the eggs, the patient will undergo a conscious sedation without receiving any anesthesia; and she will not feel any pain. They are ambulatory techniques.

What kind of rest do these human reproduction treatments require?

  • For an Artificial Insemination:
    During the treatment, you have to come to the fertility clinic 2 or 3 times to monitor the controls. The consultation period is generally 15 minutes. On the day of artificial insemination, the couple should, if required, bring a sperm sample an hour and a half before the treatment. The artificial insemination is a process which lasts for fifteen minutes and which does not require any special rest, neither on the same day nor on the next. You can therefore restart your professional activities without any difficult, but without making any violent effort. By coordinating the meetings with the gynecologist, you can go for check-ups and for the artificial insemination treatment beyond working hours.
  • For an In Vitro Fertilization:
    The woman should go for a consultation for a check-up 3 to 5 times, depending on the type of assisted reproduction treatment. The consultation period is approximately 15 minutes. On the day of extraction of eggs, the couple should bring a sperm sample and the woman will enter the operating block for a period of 30 minutes. The intervention is done under sedation and the woman can then leave. The transfer of embryos will take place 48-72 hours later. The operation lasts for 15 minutes and a 48 hours relative rest is recommended. The woman can then restart her normal life, but without any important efforts.
  • In case of foreign patients or associated gynecologists, the controls of the cycle may be performed outside our assisted reproduction center, such that the patient needs to come to Tarragona (Reus) only on the day of extraction of eggs and on the day of transfer of embryos; and for an artificial insemination, on the day of insemination.

During the in vitro fertilization cycles, how many eggs do we extract and how many embryos should we obtain?

All the inserted follicles do not necessarily contain an egg and certain of the eggs obtained are not convenient for fertilization. The number of eggs obtained will vary depending on the case: sometimes we obtain only few eggs, sometimes the number is very high. It all depends on the age, the quality of the sperm and the response to the treatment. The number of eggs obtained is on average 5 to 10, and 3 to 6 fertilized embryos in women less than 35 years.

I am having lots of problems with the treatment and I am very anxious. What can I do?

The assisted reproduction techniques are complex processes which condition a large number of aspects of your personal life and of the couple’s life. You will have doubts and fears and sentiments of intense enthusiasm and impatience. Procrear, our assisted reproduction center, provides its patients with professionals that will solve all the doubts derived from the treatment, thanks to their experience. If required, our team will provide a psychologist whose aim will be to psychologically prepare the patients to confront the treatment in the best possible way and by teaching them relaxation and anxiety reduction techniques.

At what time can I perform the pregnancy test after the treatment?

If at the end of 13 days, you don’t have your periods, we recommend performing a blood test (BETA-HCG in the blood). If the test is positive, you are pregnant. You will then have to continue the treatment until you have a consultation (two weeks later). We will now check by ultrasound if effectively, the pregnancy has progressed and if the heart of the embryo is beating.

My periods returned. Should I still continue?

A failed treatment can consequently lead to a psychological depression and loss of trust, logic in the technique and the team. By consulting the gynecologist, you can understand the degree of difficulty of your case; know whether you have to change techniques or treatments, or if it’s better to stop trying. After many tries, the accumulated probability of pregnancy increases.

Can we select embryos implanted safely?

It is currently not possible. The only thing that we can do is select embryos that, from a morphological perspective, show the best quality (a better “aspect”). If the number of embryos is enough and appropriate to your specific case, we can opt for a long term culture of embryos or blastocysts, or for a pre-implant diagnosis to increase the chances of implantation.

Are the children born under this technique the same as other children?

Yes. They show the same risks of genetic alterations, malformation, etc. as the normal population. Only in certain genetic male sterility cases, there is the risk of transmitting the paternal sterility to the son while using the intracytoplasmatic micro-injection of sperms (ICSI) and so, the son will have to rely on this technique too to become a father.

Are the procedures of pregnancy and delivery the same as that in a natural process?

Yes. Although in our assisted reproduction center, we establish a specific protocol to monitor the pregnancies obtained after an assisted human reproduction.

About the oocyte donation

Who can donate oocytes?

The oocyte donors are young healthy women that want to help other women in becoming mothers. They are generally socially engaged and of a high cultural level. Many of them are university students.

In our Center, the require conditions are: being between 18 and 28 years, possess a negative family medical file concerning genetic transmission diseases, present a normal Karyotope (chromosome analysis), a negative genetic disease screening, a negative complete report with regard to sexually transmissible diseases (aids, hepatitis B and C, syphilis), a normal reproducing device, good physical and mental health, good fertility and response to the ovary stimulation treatment, and an appropriate corporal mass index. The donation is anonymous (the information about the identity of donors remains a secret). The oocyte donation is an altruistic act, but an economic compensation is allowed to cover the travelling expenses, leaves of absence, etc.

How can I become a donor?

To become a donor, please contact our assisted reproduction center and plan a meeting.

contact-us

Is the process painful?

The oocyte donation is not painful. The most common irritation is a pinch in the abdomen similar to what is felt during ovulation.

Can a donation affect my subsequent fertility?

No. The oocyte donation will not affect your future fertility. By using a strict preliminary gynecological report, you can diagnose and process alterations which, in short term, could compromise your fertility.
