Seminal lavage: what is it and what is it used for?
Human immunodeficiency virus (HIV), hepatitis C (HCV) and hepatitis B (HBV) are viruses that are transmitted through blood and body fluids as well as through vertical transmission (from the mother to the foetus). As a result, couples […]
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 […]
Oocyte quality is one of the most important of the factors that have an impact on fertility in women. Optimum oocyte quality generally gives rise to embryos with an increased ability to implant in the uterus.
Fragile X chromosome syndrome and fertility
What are the physical characteristics and symptoms of the X Fragile syndrome? Fragile X syndrome is one of the most common causes of hereditary intellectual disability. The gene responsible for the disease is known as […]
The spermatozoa in ejaculate need to have gone through a process known as sperm capacitation in order to obtain the ability to fertilise. This happens naturally in the female reproductive system and techniques in order to […]
Effects of advanced paternal age on fertility
Owing to sociocultural and economic factors, there has been a considerable increase in recent years in the number of men over the age of 35 who wish to have children. As a couple ages, the […]
Embryo transfer on day 4 – why not?
In most laboratories, embryo transfer traditionally takes place on day 2 to 3 of culture, or during blastocyst stage, whilst embryo transfer on day 4 is an alternative that has not commonly been adopted into laboratory practice. When compared with […]
From the very moment when sperm fertilises an ova, a new embryo starts developing and a large number of cell divisions take place. This embryo development is observed in an in vitro fertilisation laboratory up until the […]
Are sterility and infertility the same? No, they are two completely different concepts. Sterility is the inability to conceive whilst infertility is the inability to complete a full term pregnancy and give birth to a healthy child. […]
