LONDON, July 6,2020 /PRNewswire/ --IVIRMA, a global network of fertility clinics and world-leading pioneer in fertility research, are presenting a breakthrough study at the 36th Congress of the European Society of Human Reproduction and Embryology (ESHRE) today, demonstrating the possibility of 're-awakening' the ovaries in women under 40 (38 years and below) with the lowest reproductive reserve at the ovarian level.1 The ASCOT technique (involving infusion of stem cells in the ovarian artery), which has recently been shown to be successful in low-responder patients, has now shown it can achieve pregnancy in a woman with premature ovarian failure (POF).1

The study, 'Bone marrow derived stem cells restore ovarian function and fertility in premature ovarian insufficiency women. Interim report of a randomized trial: mobilization versus ovarian injection',1 which is still ongoing, includes two study arms: one using the ASCOT technique, that is, the infusion of stem cells in the ovarian artery* and, second, a less invasive option consisting of mobilising the stem cells, and allowing them to reach the ovaries through the bloodstream directly. The preliminary results have shown that ovarian follicle development was achieved in both groups, with some patients re-starting menstruation, and a decrease in menopausal symptoms. As a result of this procedure, embryos were obtained in 2 out of the 10 participants, and even one pregnancy through the ASCOT technique was achieved.

Dr. Diaz, Medical Director, IVI London, a leading fertility specialist and co-pioneer of the world's first womb transplant, commented, "We are truly excited by these very promising results achieving ovary re-awakening and pregnancy using stem cells in a woman who previously may not have had the option to conceive using her own eggs. We continually strive to pioneer on the cutting-edge of fertility research, as we know how harrowing it can be for every person struggling to conceive. These new techniques may give us potential new options for women with premature ovarian failure, in addition to those with low ovarian reserve."

It is estimated that 1 in 100 women under 40 years of age suffer from premature ovarian failure (POF) in the UK. 2.5% of all patients with POF are adolescents.2 This premature cessation of ovarian activity is one of the most challenging scenarios in terms of reproduction and can be devastating. Now, thanks to the findings of this study, led by Dr. Sonia Herraiz, researcher at the IVI Foundation-IIS la Fe, Spain and Dr. Nuria Pellicer, gynaecologist at Hospital la Fe in Valencia, Spain, there might be hope for women suffering from this fertility issue.

Dr. Nuria Pellicer, Gynaecologist, Hospital la Fe, Valencia, Spain added, "So far, we obtained embryos in 2 of the 10 patients included and one 37-week pregnancy in the ASCOT arm, in patients with almost no chance of successful pregnancy with classic in vitro fertilisation procedures. We found that both arms promoted the development of follicles, and some patients have even recovered their menstruation, thus reducing menopausal symptoms However, these are preliminary results of an ongoing study, so we remain cautious until the study is complete. We aim to develop a technique that is as minimally invasive as possible over time and standardise it so that it can be implemented in all our clinics. We would like to make it possible to offer any woman who wishes to become a mother the possibility of doing so, even when her reproductive circumstances are unfavourable."

"This is a very encouraging line of research in which we will continue to work with a single goal: to improve assisted reproduction techniques and treatments in order to obtain the best results, however difficult the reproductive prognosis may seem,"concluded Dr. Herraiz, researcher at the IVI Foundation-IIS, la Fe, Spain.

More About the Study1

In addition to this research, IVI are presenting three more studies at the ESHRE Congress:

These new techniques and other research conducted by IVI is translated and applied to the treatments available in their clinics across the world, which is in turn reflected in the achieved results. The London clinic has achieved 71.4% clinical pregnancy rates per embryos transferred in women under the age of 386 and recent data shows that with PGT-A genetic screening the evolutive pregnancy rate is 57% in women undergoing treatment at IVI London as compared to the national average of 42%.7 Furthermore, 100% of these pregnancies have been achieved through single embryo transfer, eliminating chances of multiple pregnancy and the complications that arise with it.7

More about the ASCOT technique development: 3 babies and 6 pregnancies achieved so far in low-responder patients

To date, 3 babies and 6 pregnancies have been achieved using the ASCOT technique for ovarian rejuvenation in low-responder patients with low ovarian reserve, pioneered by IVIRMA Global. The technique involves transplanting bone marrow-derived stem cells (BMDSC) into the ovarian artery, achieving a partial reversal of ageing of the ovary, the organ responsible for ovulation, and activating the dormant follicles that would otherwise remain arrested in the ovary. After its first phase in animal models to test the effectiveness of the technique with stem cells, this study went to its second phase in low-responder patients. A total of 20 patients had their stem cells mobilized, extracted from peripheral blood and implanted back into the ovary in order to reverse the ageing process and activate the dormant follicles. This technique has improved ovarian function biomarkers in 81% of low responder patients. In addition, spontaneous pregnancies occurred. In view of the success of this phase, the next stage was undertaken, which consisted of recruiting women under 38 years of age, this time with early ovarian failure (a situation with a worse reproductive prognosis that of low responders). From here the above-mentioned study arose.

IVIRMA Global and IVI London, UK

IVI was founded in 1990, as the first medical institution in Spain fully dedicated to Assisted Reproduction. Since then it has helped with the birth of more than 200,000 babies thanks to the application of the latest Assisted Reproduction technologies. In early 2017, IVI merged with RMANJ, becoming the largest Assisted Reproduction group in the world. It currently has more than 65 clinics in 9 countries and is the leading centre for Reproductive Medicine. In 2016 IVI opened its doors in London, located in the heart of the medical
