Although Spanish law led the way in regulating the practice of assisted reproduction and made significant progress in comparison with legislation in neighbouring countries, and even though Spain is, furthermore, a leader in the field both in terms of the quality of some of its clinics and health specialists, as well as in terms of the excellent results obtained, it […]
As is the case with all the organs in our bodies, over our lifetime, ovaries go through changes that affect not only their size but also how they perform. The ovaries are situated between the uterus and the fallopian tubes. They are essential to reproduction and, therefore, to the survival of the human race.
The ovaries begin to develop when female embryos are around 8 weeks old and during pregnancy they undergo a number of changes that prepare them for their role in reproduction when a woman is in her childbearing years. […]
Selection of the spermatozoon capable of fertilising an egg and generating a viable embryo is a subject that has been covered in a great number of studies aiming to provide this question with an answer.
Although assisted reproduction techniques have been used for dealing with fertility issues for many years, there is still room for improvement in terms of the results obtained. First of all, we need to fully determine the role of the spermatozoon because it tends to be thought of simply as the transporter of the father’s genetic material with no impact on later development. This idea has already been turned on its head and sperm does not only play a role in the fertilisation process. An abnormal spermatozoon can give rise to abnormal embryos and can even influence implantation failure. […]
Tropical diseases are found exclusively, or mainly, in the tropics, areas of the world that have a humid or warm climate. They are caused by parasites or viruses and are transmitted mainly by insects (for example, malaria or the Zika virus) or contaminated water (for example, hepatitis A or schistosomiasis). […]
Adenomyosis is defined as an abnormal presence of endometrial tissue inside the muscular lining of the uterus.
Adenomyosis is not a well-known condition because diagnosis is not easy. Clinical expression can range from no symptoms whatsoever to heavy, lengthy periods and dysmenorrhoea. […]
Should I tell my children they were born as a result of in vitro fertilisation (IVF) or egg donation?
One of the questions that couples frequently ask me in their appointments is if they should tell their child that they were the result of IVF or egg donation? How will the child react when told?
The answer needs to be thought through and only you will find the one that’s right for you. Your personality is based on a number of factors such as principles, education, opinions (prejudices), beliefs and experiences that shape your thoughts and, as such, the way you feel and act. In order to get a clear answer, I suggest you put those opinions aside and take all the time you need. Set your irrational thoughts aside and the answer will come to you. There are couples who do not know what they will do until their child is born. However, once you’ve decided, don’t doubt your choice. Accept the consequences and be consistent. Whatever you decide to do, be sure that it makes you happy because being happy is a decision. […]
The Internet, with its wide range of possibilities (webpages, forums, social media and so on), opens up an endless array of opportunities for obtaining information.
However, the participants are anonymous and forums often turn into a place to which negative messages can be sent. This is because satisfied patients are busy enjoying their delight at having achieved their goal and rarely go on-line to publicly share their innermost joy. […]
Significant progress has been made over the last few decades in the field of fertility in order for patients to be able to have children of their own. However, one of the greatest challenges in reproductive medicine is pregnancy in women with slim chances of obtaining their own eggs. For example, women with premature ovarian failure (in other words, egg loss at a young age) or, quite simple, women over the age of 40. […]
It has been scientifically proven that there are risk factors in our daily lives that have a negative impact on the quantity and quality of spermatozoa. These factors include emotional stress, doing a physically demanding job, sitting for prolonged periods of time, elevated local temperature, having high blood pressure and taking certain drugs over a prolonged period of time.
With this in mind, are there factors in our daily lives that are good for semen quality? […]
During in vitro fertilisation processes, for the first few days of their lives, human embryos have to develop outside the mother’s body in special incubators. Temperature and pH conditions need to be optimum and embryos also need to have access to all the necessary ingredients in order to feed and, in doing so, meet their energy requirements. Culture media are used for this. […]
