1 Review Ovarian reserve screening in infertility: practical applications and theoretical directions for research. 2009

Sills, Eric Scott / Alper, Michael M / Walsh, Anthony P H. ·Division of Reproductive Endocrinology and Infertility, Department of Obstetrics & Gynaecology, School of Medicine, Royal College of Surgeons in Ireland, The Sims Institute/Sims International Fertility Clinic, Dublin, Ireland. drscottsills@sims.ie · ·Eur J Obstet Gynecol Reprod Biol · Pubmed #19487066.

ABSTRACT: The concept of ovarian reserve describes the natural oocyte endowment and is closely associated with female age, which is the single most important factor influencing reproductive outcome. Fertility potential first declines after the age of 30 and moves downward rapidly thereafter, essentially reaching zero by the mid-40s. Conceptions beyond this age are exceedingly rare, unless oocytes obtained from a younger donor are utilised. How best to estimate ovarian reserve clinically remains controversial. Passive assessments of ovarian reserve include measurement of serum follicle stimulating hormone (FSH), oestradiol (E(2)), anti-Müllerian hormone (AMH), and inhibin-B. Ultrasound determination of antral follicle count (AFC), ovarian vascularity and ovarian volume also can have a role. The clomiphene citrate challenge test (CCCT), exogenous FSH ovarian reserve test (EFORT), and GnRH-agonist stimulation test (GAST) are provocative methods that have been used to assess ovarian reserve. Importantly, a patient's prior response to gonadotropins also provides highly valuable information about ovarian function. Regarding prediction of reproductive outcome, in vitro fertilisation (IVF) experience at our centres and elsewhere has shown that some assessments of ovarian reserve perform better than others. In this report, these tests are discussed and compared; we also present practical strategies to organise screening as presently used at our institutions. Experimental challenges to the long-held tenet of irreversible ovarian ageing are also introduced and explored. While pregnancy rates after IVF are influenced by multiple (non-ovarian) factors including in vitro laboratory conditions, semen parameters, psychological stress and technique of embryo transfer, predicting response to gonadotropin treatment nevertheless remains an important aim in the evaluation of the couple struggling with infertility.

ABSTRACT: Viewing human history through a medical lens provides a renewed appreciation for today's vexing reproductive challenges, as some modern dilemmas are actually continuations of similar challenges experienced long ago. Certainly there are many examples of assisted fertility therapy that were entirely theoretical only a generation ago, but have become commonplace in modern practice and society. In particular posthumous birth and infertility have, over time, been the focus of compelling social interest, occasionally even impacting national security and dynastic succession. While the concepts have remained static, the tools available to extend and improve reproductive success have changed radically. Appropriately regarded as confidential and private, an individual's reproductive details are typically impervious to formal study. Yet, archival sources including ancient literature and formal court records can occasionally provide evidence of otherwise deeply personal concerns of a different era. Our assessment finds the issues, worries, and desires of patients of antiquity to align closely with contemporary reproductive challenges. Because children and family have always been central to the human experience, the consequences of reproduction (or the lack thereof) can make substantial imprints upon the cultural, economic, and political landscape-irrespective of civilization or century. In this article, selected motifs are described in a broad historical context to illustrate how challenges of human reproduction have remained essentially unchanged, despite a vast accumulation of knowledge made possible by gains in reproductive science and technology. Plus ça change, plus c'est la même chose. -Jean-Baptiste Alphonse Karr (1808-1890).

3 Article Balancing selected medication costs with total number of daily injections: a preference analysis of GnRH-agonist and antagonist protocols by IVF patients. 2012

Sills, E Scott / Collins, Gary S / Salem, Shala A / Jones, Christopher A / Peck, Alison C / Salem, Rifaat D. ·Reproductive Research Division, Pacific Reproductive Center, PRC-Orange County, 10 Post, Irvine, CA 92618, USA. dr.sills@prc-ivf.com · ·Reprod Biol Endocrinol · Pubmed #22935199.

ABSTRACT: BACKGROUND: During in vitro fertilization (IVF), fertility patients are expected to self-administer many injections as part of this treatment. While newer medications have been developed to substantially reduce the number of these injections, such agents are typically much more expensive. Considering these differences in both cost and number of injections, this study compared patient preferences between GnRH-agonist and GnRH-antagonist based protocols in IVF. METHODS: Data were collected by voluntary, anonymous questionnaire at first consultation appointment. Patient opinion concerning total number of s.c. injections as a function of non-reimbursed patient cost associated with GnRH-agonist [A] and GnRH-antagonist [B] protocols in IVF was studied. RESULTS: Completed questionnaires (n = 71) revealed a mean +/- SD patient age of 34 +/- 4.1 yrs. Most (83.1%) had no prior IVF experience; 2.8% reported another medical condition requiring self-administration of subcutaneous medication(s). When out-of-pocket cost for [A] and [B] were identical, preference for [B] was registered by 50.7% patients. The tendency to favor protocol [B] was weaker among patients with a health occupation. Estimated patient costs for [A] and [B] were $259.82 +/- 11.75 and $654.55 +/- 106.34, respectively (p < 0.005). Measured patient preference for [B] diminished as the cost difference increased. CONCLUSIONS: This investigation found consistently higher non-reimbursed direct medication costs for GnRH-antagonist IVF vs. GnRH-agonist IVF protocols. A conditional preference to minimize downregulation (using GnRH-antagonist) was noted among some, but not all, IVF patient sub-groups. Compared to IVF patients with a health occupation, the preference for GnRH-antagonist was weaker than for other patients. While reducing total number of injections by using GnRH-antagonist is a desirable goal, it appears this advantage is not perceived equally by all IVF patients and its utility is likely discounted heavily by patients when nonreimbursed medication costs reach a critical level.

4 Article First reported deliveries in Ireland using surgically retrieved sperm for non-obstructive azoospermia. 2011

Walsh, A P H / Yokota, T T / Walsh, D J / Jones, B J / Coull, G D / Sills, E S. ·The Sims Institute/Sims International Fertility Clinic, Rosemount Hall, Dundrum Road, Dundrum, Dublin 14, Ireland. · ·Ir J Med Sci · Pubmed #20963511.

ABSTRACT: Couples presenting with male factor infertility comprise an important proportion of clinical reproductive endocrinology consultations. Indeed, a problem with the male is the only cause, or a contributing cause, of infertility in ~40% of infertility evaluations. Here we present the first published deliveries obtained from IVF utilising surgically retrieved sperm in Ireland; pregnancy and delivery are also described following transfer of cryopreserved/thawed embryos derived from such sperm. Finding no sperm from a semen analysis in a man without a vasectomy can be a devastating event, and substantially influences the scope of the reproductive endocrinology consultation. Successful treatment of non-obstructive azoospermia is possible without reliance on anonymous donor sperm.

5 Article A descriptive study of selected oocyte, blood and organ/tissue donation features among fertility patients in Ireland. 2010

Sills, E Scott / Collins, Gary S / Walsh, David J / Omar, Ahmed B / Salma, Umme / Walsh, Anthony P H. ·Sims IVF/Department of Obstetrics and Gynaecology, School of Medicine, Royal College of Surgeons in Ireland, Dublin, Ireland. drscottsills@sims.ie · ·Hum Fertil (Camb) · Pubmed #20722579.

ABSTRACT: OBJECTIVE: Anonymous oocyte donation and participation in organ and blood/tissue donation programmes were studied specifically among Irish fertility patients. METHODS: An anonymous questionnaire measured patient perceptions of, and participation in, blood/organ/tissue donor programmes, and to record opinion on anonymous donor oocyte compensation. RESULTS: A total of 337 patents were sampled; 56.7% had no children. None had participated in a donor oocyte programme either as donor or recipient. At baseline, 19.6% had previous in vitro fertilisation experience, more than one-third (35.9%) had donated blood anonymously, 19.9% were organ/tissue donors and 52.2% indicated that anonymous oocyte donors should receive some compensation. We found patients with infertility for extended periods were more likely to view oocyte donation favourably, compared to those with infertility of shorter durations (p = 0.022, by Krusksal-Wallis Rank Sum test). Average recommended compensation for anonymous oocyte donor was euro 2177 (range euro 200-euro 9500), and most (77.2%) favoured confidential protections for recipient and donor identity. CONCLUSION: This is the first investigation of blood and organ/tissue donation features among fertility patients in Ireland; the rate of blood donation in this group was more than 10 times higher than in the general Irish population. Protection of anonymity for both donors and recipients was supported by most patients, even opponents of compensated anonymous donation. Further studies should clarify patient perceptions about oocyte donation as a function of involvement in organ/tissue procurement programmes and blood banks.

6 Article IVF for premature ovarian failure: first reported births using oocytes donated from a twin sister. 2010

Sills, Eric Scott / Brady, Adam C / Omar, Ahmed B / Walsh, David J / Salma, Umme / Walsh, Anthony Ph. ·Division of Reproductive Endocrinology, Sims IVF, Dublin, Ireland. drscottsills@sims.ie · ·Reprod Biol Endocrinol · Pubmed #20334702.

ABSTRACT: BACKGROUND: Premature ovarian failure (POF) remains a clinically challenging entity because in vitro fertilisation (IVF) with donor oocytes is currently the only treatment known to be effective. METHODS: A 33 year-old nulligravid patient with a normal karyotype was diagnosed with POF; she had a history of failed fertility treatments and had an elevated serum FSH (42 mIU/ml). Oocytes donated by her dizygotic twin sister were used for IVF. The donor had already completed a successful pregnancy herself and subsequently produced a total of 10 oocytes after a combined FSH/LH superovulation regime. These eggs were fertilised with sperm from the recipient's husband via intracytoplasmic injection and two fresh embryos were transferred to the recipient on day three. RESULTS: A healthy twin pregnancy resulted from IVF; two boys were delivered by caesarean section at 39 weeks' gestation. Additionally, four embryos were cryopreserved for the recipient's future use. The sister-donor achieved another natural pregnancy six months after oocyte retrieval, resulting in a healthy singleton delivery. CONCLUSION: POF is believed to affect approximately 1% of reproductive age females, and POF patients with a sister who can be an oocyte donor for IVF are rare. Most such IVF patients will conceive from treatment using oocytes from an anonymous oocyte donor. This is the first report of births following sister-donor oocyte IVF in Ireland. Indeed, while sister-donor IVF has been successfully undertaken by IVF units elsewhere, this is the only known case where oocyte donation involved twin sisters. As with all types of donor gamete therapy, pre-treatment counselling is important in the circumstance of sister oocyte donation.
