IVF for premature ovarian failure: First reported births using oocytes donated from a twin sister
ABSTRACT 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.
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.
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.
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.

- "It is associated with irregular menses or secondary amenorrhoea and menopausal symptoms, as well as abnormally high baseline FSH (15). There is no effective fertility treatment for POF other than egg donation (16), while EOA is much more common (10%) in the general population and the individual is young and asymptomatic. Their baseline FSH may be within normal limits. "
ABSTRACT: Apparent rise in the incidence of infertility in females and the trend shifting towards delayed child bearing brought up the concept of ovarian ageing. Women in their early thirties show poor ovarian reserve which is an entity named as early ovarian ageing. Early ovarian ageing is mostly genetically determined, but acquired modifiable factors like smoking, or ovarian surgery have some roles. Infertility and subfertility are the only clinical recognizable sequelae in the early ovarian ageing. The worrisome fact is that the outcome of assisted reproductive techniques is also not that much encouraging. Even if ovarian priming with DHEA has raised hope in the assisted reproductive techniques for these patients, but more randomized trials are needed to support this. Screening of these women with antimullerian hormone, antral follicle count and genetic analysis may be useful for recommendation at appropriate biological time regarding conception or fertility preservation.Journal of Reproduction and Infertility 03/2013; 14(1):3-7.

ABSTRACT: For the gamete and embryo donation community, it is well recognized that the implementation of a gamete and embryo donor registry (GEDR) represents a good initiative to ensure the best possible health conditions for donor-conceived individuals. Be they national, institutional or independent, GEDR can play a major role in the transmission of health-related genetic and medical information. However, from a bioethical analysis standpoint, GEDR raise many questions regarding the extent of their beneficent nature. Based on the recent Canadian GEDR aborted attempt, this article will focus on bioethical issues and paradoxes that can impact the wellbeing of donor-conceived individuals, half-siblings, donors and parents. On one hand, the implementation of a GEDR can be ethically justified as a beneficent action towards lessening harm associated with the transmission of hereditary disease and increasing the effectiveness of preventive and therapeutic approaches. On the other hand, examined through the concept of nonpaternalistic beneficence, GEDR challenge us to recognize beneficiaries' free agency, as well as the importance to transmit reliable and pertinent information. Ultimately, beyond an individualistic application of the principle of beneficence, socioethics invite us to consider consistency with societal values as a prerequisite for achieving a common good.Reproductive biomedicine online 01/2013; 28(3).

ABSTRACT: Aims: Exposure to a structured curriculum in reproductive medicine during medical school is helpful given the high frequency of fertility and pregnancy-related issues that future physicians will encounter. This study sought to evaluate a new reproductive medicine module for medical students. Study Design: Prospective cohort study. Place and Duration of Study: Dublin, Ireland; 2008-2010. Methodology: A new educational module in reproductive medicine for upper-level medical students was initiated in 2008 at the Royal College of Surgeons in Ireland (RCSI). The module included reproductive endocrinology lectures, laboratory sessions, and direct observation of clinical consultations as a required component of an obstetrics and gynaecology rotation. Students were assigned to this module on the basis of random allocation by departmental administration. The current investigation used an anonymous questionnaire and a MCQ exam to measure academic performance and student acceptance of this module, at launch and again two years later. The first sampling was from the pilot class in 2008 and a second group was evaluated in 2010. No student was in both groups. Results: 42 of 66 students completed the evaluation in 2008, and 71 of 98 did so in 2010. Mean±SD medical student age and average examination scores were comparable for the two groups. In both samples, most students (95.5%) had no prior lectures on reproductive endocrinology, and most indicated improvement in their level of understanding after the module. Both laboratory and clinical features were scored highly by students. Conclusion: At present, there is no standardised medical student curriculum for reproductive medicine in Ireland. This report is the first to describe a structured learning experience in this subspecialty area for medical students in Ireland. Additional studies are planned to track knowledge acquisition and career impact specific to reproductive medicine based on this module.
