What is PGD?

PGD stands for Pre-implantation genetic diagnosis and is a genetic screening that can be performed in IVF treatments. During IVF treatment, the female egg is fertilized with the sperm in a laboratory environment outside the human body. The embryo is usually observed for 5 days for desirable progress before implantation back to

the female uterus. This 5-day period allows a genetic screening to be performed on the embryo in order to determine if the embryo has a genetic disease passed from the parents. This ensures that the embryo selected for transfer is free from genetic disease.

Pgd Treatment

Humans have 23 pairs of chromosomes for a total of 46. 22 of these pairs are called autosomes and are the same for both males and females. The 23^rd pair is the gender chromosome, which is different in males and females. Typically, in PGD analysis, 5-9 pairs of chromosomes are analysed for the most common genetic diseases.  This type of genetic testing enables genetic disease like Monosomy, Trisomy, Down’s syndrome to be screened. In some cases, PGD is performed to enable gender selection for families having a preference for a certain baby gender. It is also worth to note that some genetic diseases only affect a certain gender. For example genetic diseases like Duchenne muscular dystrophy or Haemophillia A only affect males, hence making it important to know the baby gender before implantation.

PGD is a general name given for all pre-implantation genetic testing and many other types of genetic testing can also be performed. The type of genetic testing to be performed can be decided based on the family history of genetic diseases.

Only drawbacks of PGD is that during the biopsy phase (a cell has to be removed from the embryo to enable genetic testing) damage could occur inhibiting the development of the embryo. In addition, despite having extremely high success rates (over 99%), the PGD screening may end up being inconclusive.

To summarize, in general families with genetic disorders, older women, women who had several miscarriages and couples wishing to do gender selection usually choose to proceed with PGD. Performing PGD helps avoid abortion when a genetic anomaly is found later in pregnancy.

What is gender selection?

Sex Selection

Gender selection (sex selection) is the process of choosing the gender of a couple’s baby before pregnancy. In order to make gender selection possible, the couple has to go through IVF treatment. In vitro ferilization treatment is the fertilization of eggs with sperm in a laboratory environment outside the human body. During this treatment, the female ovaries are stimulated to produce as many eggs as possible for the Oocyte Pick Up (OPU) phase. On the OPU day, all the healthy eggs collected from the female are fertilized with the partner’s sperm to create embryos. The embryos are then kept in incubators simulating the human body. The progress of the embryos is observed for 5 days and on the 5^th day, the healthy embryos go through genetic testing.

During this genetic testing, chromosome analysis is performed. One of the chromosomes analysed is the XY chromosome. By looking at the XY chromosome, the gender of the embryo can be determined. Only the embryos with the desired gender are then transferred back to the female once the gender of the embryos are known. After the embryo transfer is performed, pregnancy develops normally. In most cases, in addition to the XY chromosome, several other chromosomes are checked to determine if the embryo has any genetic disease like Down’s syndrome or Trisomy. Currently the gender determination screenings have a success rate of 99.9% which make it a very attractive procedure for couples wishing to choose the gender of their baby. 

Gender selection is more popular in some cultures than others where there is a strong preference for a specific gender. However, many couples also do gender selection for family balancing purposes. Regulations regarding gender selection vary between countries. Most countries only allow it for medical reasons (i.e. due to some hereditary disease that passes only to a specific gender).

Gender selection before implantation of the embryo back to the female has the added benefit of avoiding abortions when the mother is not pregnant with the desired gender. 

Only a select few countries in the world freely allow this method causing many couples to travel for this treatment. With the success rates at good clinics being at such high rates and the cost becoming more and more affordable, travelling for gender selection treatment is becoming more and more common.

Why Do UK Couples Seeking IVF Treatment Travel to North Cyprus?

Despite first IVF babies being born over 30 years ago, IVF treatments have only become mainstream in the last few years. Many UK couples seeking fertility treatment usually try the NHS but a considerable percentage is now looking to go abroad for the treatment. UK couples traditionally prefer Spain for fertility treatments but a significant number have started travelling to a less known destination for IVF treatments: North Cyprus.

The island of Cyprus long known to UK tourists as the ex-colonial sunny holiday destination is now becoming a hot spot for medical fertility tourism. But why do so many British couples travel to North Cyprus to undergo fertility treatment and join it with a holiday?

Yes, Cyprus does offer sandy beaches and year-round sunshine which already make it an attractive destination but people come to North Cyprus for things that are better than or not available in the UK fertility treatment system. The biggest reason is the regulations in the IVF industry. North Cyprus has more liberal IVF regulations compared to the rest of Europe making the industry thrive in this small island.

UK couples choose North Cyprus mainly for egg donation and gender selection procedures. For egg donation, North Cyprus offers a no-wait list, anonymous egg donation program with very reasonable treatment prices. It is a very difficult process for UK couples to go through egg donation in the UK due to the difficulty of finding an egg donor and hence the wait list associated with it. This further delay the couples wish to become parents, motivating them to travel abroad.

Couples willing to travel to North Cyprus can rapidly be matched with a donor and go through the treatment immediately after choosing to come to the island. Therefore instead of going through the long and frustrating process in the UK, the couple can literally achieve pregnancy within a few weeks after choosing the right clinic for them. Also, gender selection is not allowed anywhere in Europe except North Cyprus making the destination attractive for UK patients wishing to do family balancing.

Most UK couples wishing to undergo fertility treatment in North Cyprus spend the preparation phase, called the controlled ovarian hyper-stimulation in the UK, which lasts for 10-14 days. They then travel to North Cyprus and spend only 5-7 days there, which couples see as the perfect opportunity to join a holiday. The nature of IVF treatment is such that very few visits are required to the IVF clinic for a successful treatment procedure.

The highly specialized IVF clinics offer high pregnancy rates, but as with any medical treatment, the patients advised to do their homework before choosing the right clinic for them. With the right clinic, North Cyprus offers excellent value for money for couples seeking fertility treatment abroad.
