Merrion Christmas Card

Prof Wingfield’s study with Trinity College selected for an Award

Prof Wingfield’s study with Trinity College Dublin on uterine natural killer cells in endometriosis has been selected for a RAMI Research Award in the Biomedical Science category! See below for information on this publication.

This category received a large number of submissions, so this is a significant achievement.

The RAMI Research Awards 2017 will be held on Wed 29th November, and winners will receive a RAMI bronze medal and educational bursary.

Congratulations Prof Wingfield!!

Natural Killer Cells and Infertility

The role of natural killer (NK) immune cells in infertility is the subject of much controversy in reproductive medicine. It is important to note that circulating blood NK cells and NK cells found in the uterus have very different profiles and functions. Scientific studies in animals indicate that NK cells are in fact essential for pregnancy and development of the placental blood supply.

A recent collaborative study between Merrion Fertility Clinic and Trinity College Dublin found more immature uNK cells known as progenitors in endometrial tissue from women with endometriosis as compared to healthy patients, suggesting that uNK development is altered in the endometriotic uterus. Further analysis of these endometrial tissue samples revealed reduced levels of a growth factor called SCF in women with endometriosis, which may underlie the impaired maturation of uNK cells.

To freeze or not to freeze!?!

What women want? A scoping survey on women’s knowledge, attitudes and behaviours towards ovarian reserve testing and egg freezing.


A recent publication by MFC research staff looks for the first time at Irish women’s knowledge, attitudes and behaviours towards ovarian reserve testing and egg freezing in order to preserve their fertility.

The study, led by Dr. Yvonne O’ Brien (Clinical Research Fellow at MFC), surveyed 663 women aged 18–44 years through the use of social media. Dr. O’Brien found that a majority (60%) of women surveyed had knowledge of ovarian reserve testing, and 64.8% would be interested in having testing performed. Younger women (<30 years of age) and single women were more likely to be interested in checking their ovarian reserve. In addition, the vast majority (89.7%) of women surveyed were aware of oocyte cryopreservation, and 72.2% agreed that they would consider freezing their eggs to preserve fertility. Interestingly, a majority (62.1%) of study participants believed that it is a woman’s right to postpone pregnancy for social reasons and to freeze her eggs, with no significant difference in options noted between younger and older women.

Overall, this study concludes that Irish women are highly knowledgeable about ovarian reserve testing and social egg freezing, likely reflecting increasing awareness of these issues among the Irish public. The study also shows that women are very open to the use of these modern technologies in an attempt to avoid unintended childlessness.

Cabinet approves legislation for IVF funding

After many years of advocating for funding for IVF treatments Merrion Fertility Clinic is delighted to see that the Cabinet has supported Simon Harris’s  proposal to introduce legislation for financial aid for fertility treatments.  The World Health Organisation recognises infertility as a disease, and Ireland and Lithuania are the only two EU countries not to offer state-funding for assisted reproduction.

For the many Irish couples who cannot afford the €4,000 to €6,000 cost of one IVF treatment cycle, the commitment of government funding is very welcome and long overdue.

Donor Sperm at MFC

We are delighted to announce our new Donor Sperm service.

Getting pregnant using donor sperm is a form of assisted reproduction, where the sperm used for the treatment has been donated by someone not in a relationship with the woman who wishes to conceive. Treatment using donor sperm is an option used by patients in a number of scenarios:

  •  If you are a single woman
  • If you are in a same sex relationship (lesbian)
  • If using your partner’s sperm would be extremely unlikely to be successful / if your partner does not produce sperm / if your partner has a genetic condition which could be transmitted to offspring

Donor sperm is imported by Merrion Fertility Clinic from international sperm banks. (There are no sperm banks in Ireland). The sperm is chosen by you (with our help) and stored here until it is ready for use during your treatment. Treatment involves IUI (intrauterine insemination) or IVF.

Using donor sperm is a major decision and you should take your time. For further information please see our Donor Sperm Information or click on the following link to make an appointment at Merrion Fertility Clinic.

Prof. Wingfield’s Interview on Newstalk

Prof. Mary Wingfield discusses new research which suggests a significant drop in sperm counts in men in the Western world, with Dr. Ciara Kelly on High Noon, Newstalk.

“Researchers behind the study have made the catastrophic statement that if the trend continues humans will become extinct”
