The importance of DNA quality in sperm and its influence on embryo development

In a previous post we talked about some of the tests performed in the andrology laboratory to screen sperm prior to receiving fertility treatment. Evidence suggests that increased DNA fragmentation in sperm can negatively effect embryo quality, particularly from day 3 of embryo development, or after embryos have been transferred to the womb. DNA fragmentation test: The DNA fragmentation test aims to pinpoint possible breaks in genetic material contained in sperm. It is a specialist test that is not performed … Continue reading The importance of DNA quality in sperm and its influence on embryo development

Techniques used in andrology laboratories: MACS

This method has many benefits although only a handful of centres still currently use it. For over twenty-five years, magnetic-activated cell sorting (MACS) has been used for treatment when the male factor has a big impact. The method enables the best sperm to be selected, thus increasing the chances of fertilisation. For severe male factor infertility, sperm quality can affect the treatment’s success rate as it affects the development of the fertilisation process in its early hours. In the 1990s, … Continue reading Techniques used in andrology laboratories: MACS

Sperm analysis

Sperm analysis Sperm analysis is the most comprehensive test available to assess sperm quality. It can be used to ascertain the ejaculate volume, sperm count per millilitre, morphology, motility, vitality and the presence of binders. Sperm analysis can be used in conjunction with other more specific tests, such as motile sperm count or a sperm survival test. Sperm analysis enables certain pathologies to be diagnosed, such as: – Oligospermia: less than 15 million sperm in semen sample – Asthenospermia: less … Continue reading Sperm analysis
