Balearic In Vitro Fertilization Centre, CEFIVBA, Assisted Reproduction Unit of USP Hospital Palmaplanas in Balearic Islands Palma de Mallorca (Spain) has recently acquired a new system for embryo incubation at low oxygen tension, which already use the couples who come to the unity of Palma to perform a cycle of "in vitro" fertilization.

With this new incubator, the incubation of embryos is closer to its natural state in the tubes where there is a low oxygen tension. Until now, the incubation was performed at 37° C and a CO2 concentration to provide the optimum pH for development, in an attempt to mimic the natural conditions in which an embryo would develop in the tubes. With this new incubator, designed for assisted reproduction, the oxygen is displaced in order to reach the desired conditions.

This represents a significant advance in terms of culture conditions of embryos which is reflected in increased pregnancy rates.
According to data from assisted reproduction clinics about 40% of women undergoing fertility treatments in Spain are single women.

Spanish Fertility Society (SEF) speaks of more than 1,500 women a year who choose to be single mothers undergoing artificial insemination with donor sperm or in vitro fertilization with donor semen. To these must be added the foreign women who use the Spanish health system.

In the same way sperm donation is used more by women alone than for indication of male pathology. Less than 10 years ago sperm donation was used in four out of five cases because the man of a heterosexual couple had fertility problems in their sperm. Today this trend has changed and sperm donation is requested mainly by heterosexual women who want to be mothers alone.

Homosexual women also have access to these techniques but the group of heterosexual women who decide to have a child alone through sperm donation are the overwhelming majority.

The advent of assisted reproductive techniques opened the door to a solution to the problems of infertility, but the success of treatment still faces the same obstacle: late motherhood.

The age at which women choose to have their first child has increased to around 33, when two decades ago the average was about 26 years. Currently the average age of patients attending consultations also increased to more than 38 years.

The social clock for childbearing has been delayed a lot, but not the biological clock, which is a biological barrier for parents, more and more difficult to overcome.

The limit for this technique in the spanish public network is usually 40 years, so more elderly women often resort to private clinics where there is no one-year waiting to be served.

We can not speak about an age top to provide assisted reproductive services. In the private network exclusion criteria is usually measured by the biological age which carries a complete study of the patient and biological health status and ability to carry a pregnancy to term.

Researchers at the University of Murcia in collaboration with Harvard University have found that a Mediterranean diet rich in fish, fruits, vegetables and cereals increases the rate of motile sperm.

The study presented at the recent annual meeting of the American Society for Reproductive Medicine held in Orlando (USA) aimed to study the correlation between dietary habits and parameters in healthy young semen.

The study of food habits of 188 young men were classified as "mediterranean" or "western" (high in red meat, processed meats, pizza, snacks, candy and energy drinks). Were adjusted for potential confounders such as smoking, total caloric intake, abstinence time, body mass index (BMI) and level of physical exercise and the result was that the "western" diet were associated with reduced movement. While diet "mediterranean" does not seem related to the shape or number of sperm motility was affected if.

Currently the study is replicated in the Region of Murcia.

Previous studies associated intake of fruits and vegetables rich in vitamins with the best semen quality. The hypothesis is that antioxidants contained in such foods could help improve, or at least preserve, the sperm quality, mainly avoiding oxidative stress processes.

Spain is one of the countries with higher rates of assisted reproduction interventions in Europe and yet dosen't have an updated record for Assisted reproduction clinics and furthermore there is no census of embryology professionals.

This situation, in the Spanish economic context of the current crisis, may lead to diminishing the quality of care offered by these centers. There is no legislation to ensure continuity in the quality of these procedures.

For this reason, ASEBIR (Spanish Association of Reproductive Biology) CEFIVBA professionals belong and Aenor develop a standard for quality control, specific for assisted reproduction laboratory.

We are the third European country in relation to the number of assisted reproduction cycles and yet we do not have a specialty of Clinical Embryology, nor a record of over 700 professionals dedicated to this task, it is the responsibility of the Ministry of Health.

Another gap is the absence of a donor registry. The law sets a limit of six children born to donors, but this record anyone can go different clinics and over again without knowing.
