i-Port: bidding farewell to injections during ovarian stimulation

At Instituto Bernabeu, we are bidding farewell to ovarian stimulation injections during courses of in vitro fertilisation (IVF) treatment. The clinic is launching an innovative device called i-Port Advance™ for self-administration of drugs using a system that is already used by diabetics and which is being put to gynaecological use. By using this device, Instituto Bernabeu is revolutionising the future of assisted reproduction and making administration of injectable drugs easier. In short, it takes the stress out of having to have one, or sometimes more than one, daily injection. […]

Physiological conditions in embryo culture: reduction of the amount of oxygen in the incubator

Improving embryo culture by mimicking the conditions generated during in vivo culture is a key contributor towards improving success rates in couples who turn to in vitro fertilisation in order to solve their sterility issue.
In vitro culture of human embryos has traditionally been carried out in incubators in a controlled atmosphere at 6% CO2 and 21% O2. However, based on studies carried out on different species of mammals, we know that these conditions do not match those found in vivo in the fallopian tubes and the uterus where oxygen tension ranges between 2 and 8%. […]

Choosing a fertilisation technique when oocyte counts are poor. IVF or ICSI?

A low ovarian response is an increasingly common situation for clinicians. It is mainly associated with delayed motherhood and, accordingly, with lower ovarian reserves. In this type of patients, the number of oocytes retrieved after puncture is normally limited. In this situation, choosing the most adequate fertilisation technique, conventional IVF or Intracytoplasmic Sperm Injection (ICSI), may stir a little controversy (of course, provided that the sperm quality and the medical history lead us to consider conventional IVF as a reasonable option). […]

Azoospermia in the IVF lab

Azoospermia is defined as the absence of sperm in the ejaculate, which is generally classified as either obstructive or secretory. In obstructive azoospermia, the sperm cells cannot complete their journey from the testicle to the urethra through the seminal tract; however, the sperm cells are produced in the testicle (spermatogenesis). […]
