Imogen Goold
In 'Egg Freezing and Egg Banking: Empowerment and Alienation in Assisted Reproduction', John A Robertson responds to the American Society of Reproductive Medicine's statement that oocyte preservation should no longer be considered an experimental treatment. He explores the implications of this development, focusing on the potentially empowering impact of oocyte preservation as a means for women to preserve their fertility. He also engages with concerns about the possibility that such a development may raise issues of alienation...

BACKGROUND: Egg donation is a common fertility treatment in female cancer survivors with reproductive wish and iatrogenic ovarian failure. We examined whether women previously treated for cancer have a higher risk of pregnancy complications after egg donation treatments when compared to women without cancer history. METHODS: In this prospective cohort treated during 2003-2015 at a single center, 31 women with previous history of cancer achieved 25 deliveries and 212 women without cancer history achieved 244 deliveries...

STUDY QUESTION: What are the perspectives of adolescents conceived using surrogacy, egg or sperm donation regarding their conception and the third party involved? SUMMARY ANSWER: The majority of adolescents described feeling indifferent about their conception, and yet simultaneously reported an interest in the third party involved, or were in contact with them. WHAT IS KNOWN ALREADY: There is an assumption that children conceived through reproductive donation will feel negatively about their origins in adolescence...

Public discourses commonly frame gamete, organ and other forms of bodily donation as altruistic 'gifts'. However, despite on-going debates about the ethics of payments to donors, few studies have examined the views of donors themselves regarding the meaning of payments and their compatibility (or not) with understandings of these practices as gifts. This article addresses this issue, analysing 24 in-depth interviews with UK identity-release gamete donors. It was crucial to all participants that their donation be viewed as fundamentally other-oriented, motivated by the desire to help others...

Riikka Homanen
The multimillion-euro fertility industry increasingly tailors its treatments to infertile people who are willing to travel across national borders for treatments inaccessible at home, especially reproductive tissue donor treatments. Finland is the Nordic destination for access to donor eggs, particularly for Swedes and Norwegians hoping for a donor match that will achieve a child of phenotypically plausible biological descent. Finns are seen as Nordic kin, and the inheritability of "Nordicness" is reinforced at clinics...

BACKGROUND: Preventive chemotherapy with donated anthelminthic drugs is the cornerstone for the control of helminthiases. However, reinfection can occur rapidly in the absence of clean water and sanitation coupled with unhygienic behaviour. The purpose of this study was to assess the effect of an integrated package of interventions, consisting of preventive chemotherapy, community-led total sanitation (CLTS) and health education, on the prevalence of helminth and intestinal protozoa infections and on participants' knowledge, attitude, practice and beliefs (KAPB) towards these diseases including water, sanitation and hygiene (WASH)...

Genomic based technologies are firmly implanted into clinical medicine. They arrived rapidly and their uses continue to evolve in both the pre and postconception periods. These technologies migrated from the prenatal arena into the domain of the reproductive endocrinology and infertility specialists in some cases nearly simultaneously (expanded carrier screening), in others more slowly (chromosome microarrays), and for some technologies the ethical and cost concerns have resulted in a slower diffusion across the disciplines...

OBJECTIVE: Advanced paternal age is related to poor sperm quality; however, little is known on its effect on aneuploidy embryo rates and, more importantly, on chromosomal abnormalities like trisomy 21, 18 and 13. The objective of this study was to evaluate the effect of advanced paternal age on the trisomy rates of the chromosomes 21, 18 or 13 in embryos obtained from donated oocytes. METHODS: A total of 378 embryos, obtained from 52 IVF/ICSI cycles with donated oocytes in conjunction with PGD, were allocated according to paternal age in three groups: Group A: ≤39 years (n=115 embryos), Group B: 40-49 years (n=157 embryos) and Group C: ≥50 year (n=106 embryos)...

STUDY QUESTION: How do gay father families experience surrogacy in terms of their relationships with surrogates and egg donors, fathers' disclosure decisions and children's views on their surrogacy origins? SUMMARY ANSWER: More families had a relationship with the surrogate than the egg donor, and almost all had started to disclose to their children, the majority of whom expressed limited interest in their surrogacy conception. WHAT IS KNOWN ALREADY: Gay fathers tend to report greater contact with the surrogate than the egg donor and to disclose only the use of a surrogate (omitting discussion of the egg donor and the respective fathers' genetic relatedness)...

PURPOSE: During the transitional phase of premature ovarian insufficiency (POI), sporadic resumption of ovulation is possible because of fluctuation of hormonal levels but the chance of spontaneous pregnancy is low, and the main perspective of childbearing in these women is egg donation or adoption. The purpose of the study was to verify whether treatment with estrogens in POI patients in transitional phase could reduce FSH levels and to evaluate if this pre-treatment could improve reproductive outcomes of in vitro fertilization (IVF)...

This paper argues that the convention of allocating donated gametes on a 'first come, first served' basis should be replaced with an allocation system that takes into account more morally relevant criteria than waiting time. This conclusion was developed using an empirical bioethics methodology, which involved a study of the views of 18 staff members from seven U.K. fertility clinics, and 20 academics, policy-makers, representatives of patient groups, and other relevant professionals, on the allocation of donated sperm and eggs...

Males of many butterfly species secrete long-lasting mating plugs to prevent their mates from copulating with other males, thus ensuring their sperm will fertilize all future eggs laid. Certain species have further developed a greatly enlarged, often spectacular, externalized plug, termed a sphragis. This distinctive structure results from complex adaptations in both male and female genitalia and is qualitatively distinct from the amorphous, internal mating plugs of other species. Intermediate conditions between internal plug and external sphragis are rare...

Endometriosis is a common condition, causing pain and infertility. In infertile woman with superficial peritoneal endometriosis and patent tubes, laparoscopy is recommended, followed by ovarian stimulation alone or in combination with intrauterine inseminations. In case of ovarian or deep endometriosis, the indications of surgery and assisted reproductive technologies remain to be defined precisely. In vitro fertilization is generally proposed after the failure of up to three inseminations, directly for ovarian or deep endometriosis, or in case of an associated factor of infertility, mainly male...

STUDY QUESTION: Are there any changes in the treatments involving ART and IUI initiated in Europe during 2013 compared with previous years? SUMMARY ANSWER: An increase in the overall number of ART cycles resulting from a higher number of countries reporting data was evident, the pregnancy rates (PRs) in 2013 remained stable compared with those reported in 2012, the number of transfers with multiple embryos (3+) was lower than ever before yet the multiple delivery rates (DRs) remained unchanged, and IUI activity and success rates were similar to those of last years...

Children created through mitochondrial replacement techniques (MRTs) are commonly presented as possessing 50% of their mother's nuclear DNA, 50% of their father's nuclear DNA and the mitochondrial DNA of an egg donor. This lab-engineered genetic composition has prompted two questions: Do children who are the product of an MRT procedure have three genetic parents? And, do MRT egg donors have parental responsibilities for the children created? In this paper, I address the second question and in doing so I also address the first one...

OBJECTIVE: To compare obstetrical and neonatal outcomes of twin pregnancies conceived via assisted reproductive technology (ART) with those of naturally conceived ones and to investigate the influence of the ART procedure type on these parameters. PATIENTS AND METHODS: This observational study included 450 ART and 647 spontaneous twin pregnancies delivered over 15 years at a single university-based hospital of Rome, Italy. Logistic and linear regression models adjusted for confounding factors were used to evaluate the effect of ART and the type of assisted conception (IVF/ICSI, ovulation induction ± intrauterine insemination, egg/embryo donation) on maternal and perinatal outcomes...

The use of immature oocytes subjected to in vitro maturation (IVM) opens interesting perspectives for fertility preservation where ovarian reserves are damaged by pathologies or therapies, as in PCO/PCOS and cancer patients. Human oocyte cryopreservation may offer some advantages compared to embryo freezing, such as fertility preservation in women at risk of losing fertility due to oncological treatment or chronic disease, egg donation and postponing childbirth. It also eliminates religious and/or other ethical, legal, and moral concerns of embryo freezing...

PURPOSE: Advances in reproductive techniques, mainly the introduction of oocyte vitrification, have provided the opportunity to conceive from oocyte banks. The aim of this study was to compare the clinical outcomes of fresh and vitrified oocytes in an egg donation program following blastocyst transfer. METHODS: This retrospective observational study included 504 oocyte donation cycles. All donor women were younger than 30 years of age. The recipient cycles were divided into two groups: fresh oocytes (n = 78) or vitrified oocytes (n = 426)...

Spain's plummeting fertility since the late twentieth century may seem to reflect a waning desire for children. Nevertheless, reproductive disappointments resulting from gender inequalities cause many Spanish women to postpone motherhood and experience age-related fertility problems. For them, creating a family often becomes possible only through the reproductive labor of other women. Our analysis of transnational adoption, egg donation, and surrogacy in Spain shows how anonymity and altruism play out in these three strategies, with implications for the valuation of women's reproductive work and relationships among reproductive providers, intermediaries, recipients, and the resulting children...
