The technology behind the cryopreservation of reproductive cells and tissues is based on scientific principles that were evolved during the past 50 years. The use of liquid nitrogen in sperm cryopreservation at -196oC was introduced during the 1960s, followed by reports of success in assisted reproductive methods, pregnancies and births. The first successful pregnancy by [...]
The Human Fertilization and Embryology Authority (HFEA) recently decided to extend the duration of semen cryopreservation in Great Britain up to 55 years. The time for which semen remains cryopreserved in liquid nitrogen does not affect the functional capacities of the spermatozoa, as at the state of ‘suspended animation’ all cellular functional activity is paused. [...]
According to recently published scientific data, a constant decline in sperm concentration was observed in France between 1989 and 2005, at a rate of 32.2% in total or a yearly rate of 1.9%. In addition, lower percentages of normal sperm morphology were recorded during the same 17-year period. These results are in accordance with the [...]
From April 30th to May 4th 2014, the first Athens Science and Innovation Festival took place in Technopolis, titled: ‘Science in Everyday Life’. The Festival was organized under the auspices of Athens Municipality, aiming to unlock the ‘mysteries’ of everyday life and to introduce the public to various scientific issues in a simple and comprehensible [...]
The most recent data provided by Eurostat with regard to the low birth rates in Europe and especially in our country, are very alarming: the mean European fertility rate is 1.57, whereas the necessary rate for a complete population renewal without the need of immigration should reach 2.1. Greece is rated 17th among European countries, [...]
