Polycystic Ovary Syndrome

The term polycystic ovary syndrome is used to define an ultrasound diagnosis characterised by the presence of 12 or more follicles in each ovary (between 2 and 9 mm in diameter) and/or an incremented ovary volume (>10 ml). Findings such as these in ultrasounds in a single ovary are sufficient in order to be able to give a diagnosis. However, since taking oral contraceptives can change ovary morphology, this diagnostic criteria does not apply to women who take oral contraceptives.
From a practical point of view, when assisted reproduction technology (ART) is being used, detection of polycystic ovaries in isolation is useful for predicting the ovary’s response to stimulation using drugs and the risk of ovarian hyperstimulation syndrome. […]

Seminal lavage in males with HIV

Human immunodeficiency virus (HIV) is a retrovirus and, during its most advanced stage of infection, it leads to acquired immunodeficiency syndrome (AIDS). Whilst there is currently no cure for HIV/AIDS, antiretroviral treatments do exist that stop the symptoms from developing or delay them until later. As such, we come across increasing numbers of couples of childbearing age who wish to have children and in which one of the partners is a carrier of the virus. […]

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%. […]

First Pregnancy Scan after IVF Treatment

 Confirming pregnancy after IVF and Egg Donation . The first ultrasound in which we can see the pregnancy  is a very emotional time for the parents, especially for patients who have gone through  treatments for assisted reproduction. For these patients, after having a positive pregnancy test , their anxiety does not go away but gets stronger until the pregnancy is seen to develop normally. Therefore it is very important to know what happens during this exploration, and what to expect. […]
