It is estimated that about 20% of reproductive problems are genetic or chromosomal type. That is why today genetic testing is an essential part of the fertility study in couples who come to our clinic looking for descendants.
For the diagnosis of fertility problems there is a set of genetic studies very useful in the assistance of couples with reproductive desire. Tests such as the karyotype in both partners, microdeletion of the Y chromosome in the male or the molecular study of fragile X syndrome in women are usually required tests to determine a possible genetic basis of fertility problems in couples.

Currently, oocyte donation is probably the most demanded technique in fertility centers, mainly due to the increase of maternal age. Voluntary participation of donors is essential, but donors must be evaluated carefully in order to avoid unsatisfactory results (do not forget that the ultimate goal is the birth of a healthy child without prejudice to the donor or the recipient couple).
In a recent study carried out in our center and presented at the Congress of the British Fertility Society, the leading causes of rejection in our program were evaluated in 560 potential egg donors. Continue Reading »
New technologies are making remarkable progress in the diagnosis of fertility. The latest development that has been incorporated into the range of diagnostic techniques is called array-CGH.
This new genetic test allows us to analyze our cells’ DNA to limits that years ago we would have considered pure science fiction.
The human genome is made up of 46 chromosomes: 23 from the father and 23 from the mother. All of our organism’s genetic information is stored in these chromosomes. The excess or defect of any chromosome region may be responsible for certain diseases or fertility problems, such as implantation failure or recurrent miscarriages. Continue Reading »
Preimplantation Genetic Diagnosis (PGD) is a new technique used in Reproductive Medicine and is one of the main sources of innovation and research. PGD allows embryos to be selected from assisted reproduction cycles and tested for certain genetic or chromosomal abnormalitybefore being transferred to the womb.
Azoospermia is defined as the absence of sperm in the ejaculate, which is generally classified as either obstructive or secretory. In obstructive azoospermia, the sperm cells cannot complete their journey from the testicle to the urethra through the seminal tract; however, the sperm cells are produced in the testicle (spermatogenesis).

All our genetic information is encoded in DNA. DNA is found in the nucleus of every cell of our body as part of the structures called chromosomes. The analysis of these chromosomes is called a karyotype. Continue Reading »
A seminogramme or spermiogramme is one of the basic studies performed on men to determine the sperm quality. Sperm is analysed from both a macroscopic and microscopic viewpoint. The most relevant parameters of the study are threefold:
The information that we can offer online does not replace the direct professional opinion of the doctor after a comprehensive assessment of your personal case and medical history. Therefore, we encourage your to request an appointment with our medical team either in person or through an online video conference if you are unable to travel to one of our clinics in Alicante, Elche, Cartagena or Benidorm.
