Over the last three decades there have been drastic social changes, with severe repercussions especially on fertility. According to the data published by the Spanish Fertility Society (SEF), a significant drop in reproductive capacity has characterised the last 30 years, in particular the last decade. In Spain around 15-18% of couples suffer from infertility. This drop is directly linked to social changes, such as the age at which couples seek the first pregnancy, which is postponed more and more.
Semen quality among Spaniards is constantly decreasing. It is important to bear in mind that not only the sperm count is relevant, but also its physiologic capacity to fertilise. This has to do with eating habits, exposition to toxic environments, consumption of alcohol, tobacco and drugs and level of stress. All these, among other factors, can have an impact on the sperm. A sperm analysis is a simple and quick test that can provide us with lots of information about men’s reproductive health.
There are currently sperm banks where to keep sperm samples for long periods of time, without losing their reproductive capacity. Most people associate them with banks where donors’ samples are stored, but this is not their only function. They also store sperm samples of men that, for different reasons, want to postpone the moment of having a child without losing in the future their current sperm quality or men that would like to undergo a vasectomy, but want to store samples in case they change their mind later (the saying “prevention is better than cure” applies here too!).
