Professor Wingfield discusses the impact endometriosis can have on fertility

Professor Wingfield discusses the impact endometriosis can have on fertility with Arlene Harris.

“It is estimated that one third of women with endometriosis have fertility issues; however, many don’t and endometriosis has been found in women who have several children.

Very bad endometriosis can cause adhesions or scarring within the pelvis and this damages the ovaries, making it difficult for an ovulated egg to find its way into the fallopian tube. In milder forms, the endometriosis lesions cause inflammation or a reaction in the pelvis and toxins are produced which can affect sperm, eggs or embryos.”

Endometrial scratch

Endometrial scratch is a procedure offered by MFC to suitable patients. It involves taking a biopsy of the endometrium or lining of the uterus (womb). If it is done approximately 7 days before starting stimulation for an IVF cycle, it has been shown to improve pregnancy success rates in some women. These are women who have had two or more previous embryo transfers with good quality embryos but where implantation has not occurred and they have not conceived.

ES still requires further international study to determine if it is of benefit in other groups e.g. women trying naturally, IUI, first IVF cycles or frozen embryo cycles. A large international review has just been published by the Cochrane Library which confirms a benefit for some couples but which urges caution until the results of bigger studies become available.

Using Apps to Predict Fertility

Recently published research indicates that electronic resources used by the public to predict fertile windows are “generally inaccurate”. While they may help women to calculate their day of ovulation, we know that women are also fertile on the five days coming up to ovulation. This six –day period is called the fertile window and can vary from cycle to cycle if the woman has an irregular cycle.

Only one of 20 web sites and 3 of 33 apps studied were found to be accurate.

While these devices may help a woman track her cycle, it is important that women don’t rely on them. Please feel free to discuss this with oyur doctors at your appointment.

Outpatient hysteroscopy presentation

Outpatient hysteroscopy clinics are conducted on a weekly basis in the Gynaecology Outpatient Department in the National Maternity Hospital.

Over 300 women were seen in this clinic in 2015 and almost 200 women had a hysteroscopy. The women seen in this clinic have a variety of issues including post-menopausal bleeding, infertility, suspected uterine abnormalities and recurrent miscarriages. This out-patient service ensures that women avoid having unnecessary general anesthetics but still get appropriate investigations and management of their conditions.


Dr Yvonne O’Brien and Dr Mary Wingfield presented their findings of a study that was carried out in Merrion Fertility Clinic at the Irish Fertility Society meeting in Clane on the 13th May 2016. They reported how 117 couples who attended the clinic for investigations of sub-fertility in 2015 had spontaneously conceived. They highlighted the fact that many couples do not need treatment and that it is important for clinics to have a holistic approach to couples with difficulty conceiving. History, examination and appropriate investigations are essential in the management of couples with sub-fertility.

At Merrion Fertility Clinic, we strive to create and offer a balanced, holistic approach to the investigation and treatment of sub-fertility. We individualise people’s care, offering couples the most suitable options for them. We acknowledge that for some couples IVF is the most suitable treatment option. But we also are very aware that not everyone needs or wants IVF and we are in a position to offer other options which can be as successful as IVF for many of our patients including ovulation induction, surgical interventions and complimentary therapies including acupuncture and psycho-sexual counselling if appropriate.

Egg Freezing at MFC

We are delighted to announce our new Egg freezing (Oocyte Vitrification) service.

Egg freezing has been around for a while and success rates are improving all the time. Having said that, the success rates are variable and it would always be preferable for a woman to try to conceive as soon as she can rather than postponing pregnancy and freezing her eggs. Egg freezing is less effective than natural pregnancy and requires ICSI, a type of IVF.

It is an option to consider for women who not currently in a position to conceive but hope to do so in the future. This includes women who are concerned that they are getting older and have not met the right partner or women with cancer, severe endometriosis or low ovarian reserve.

The younger the woman the better the success rates so we recommend you talk to us sooner rather than later if you are wondering about freezing.
