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...

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...

The aim of the 6th phase of this longitudinal study was to establish whether children born through assisted reproduction involving reproductive donation were at risk for psychological problems following the transition to adolescence at age 14 and, if so, to examine the nature of these problems and the mechanisms involved. Eighty-seven families formed through reproductive donation, including 32 donor insemination families, 27 egg donation families, and 28 surrogacy families, were compared with 54 natural conception families...

Promoted by sexual selection, males usually adopt different ways to increase their fertilization chances. In many insect taxa males donate nuptial gifts, together with sperm, which represent a valuable additional nutrient source that females can use to provision eggs. This has also been suggested to occur in simultaneous hermaphrodites, organisms with both sex functions. In theory, donation of nuptial gifts or extra nutrients might work in hermaphrodites that mate unilaterally (one-way donation of ejaculates), but will not be effective when these organisms mate reciprocally (mutual exchange of ejaculates), since on average each partner would receive the amount it also transfers...

Women doing in vitro fertilization (IVF) to have a child describe it as painful and emotionally draining. Egg donors undergo the same medical regimen for a different reason - to produce eggs for another woman in exchange for thousands of dollars - and describe it as quick and relatively painless. Medical researchers typically compare bodily responses by variables such as gender, age, and health status. We use the case of "egg production" to propose a new factor that may be an important source of variation in bodily experience: an individual's reason for undergoing the medical intervention in the first place...

In the discussions leading up to the enactment of the UK Human Fertilisation and Embryology (Mitochondrial Donation) Regulations 2015, it was repeatedly emphasised, by many commentators, that maternal spindle transfer (MST) and pronuclear transfer (PNT) did not give rise to children who could be considered as having three or more parents. This was because it was argued that only the genetic material found in the chromosomes should be considered as the determining factor for the formation of parent-child relationships and the resulting kinship identities...

Iron is a 'one-way' element and the primary point of regulation of body iron stores is at the level of intestinal iron absorption. Repeated blood transfusions for congenital anaemias bypass this regulatory checkpoint and inevitably lead to iron overload in the long-term. Iron overload causes multi-organ dysfunction of the heart, liver, pancreas and joints. It also causes reproductive toxicity primarily through its damaging effect on the anterior pituitary leading to hypogonadotrophic hypogonadism. Another less understood mechanism of reproductive toxicity is direct gonadal damage of excess free iron...

This paper reports on a study of the views and experiences of 21 sperm donors and five egg donors registered with UK DonorLink (UKDL), a voluntary DNA-based contact register established to facilitate contact between adults who wish to identify and locate others to whom they are genetically related following donor conception. Specifically, the paper examines donors' reasons for searching for, or making information about themselves available to donor-conceived offspring. Their expectations of registration with UKDL, experiences of being registered and finally, the experiences of those who had contacted donor-conceived offspring and other genetic relatives are investigated...

Since the late 1990s, assisted reproductive technologies (ARTs) have been legitimized in Iran through an official religious endorsement. Iran, under the dominant authority of the Shia sect, is now the most enthusiastic adopter of ARTs in the Muslim world, permitting all forms of treatments, including third party donation. This study examined the public perception of assisted conception and its influence on the adoption of these methods in Iran. The study was questionnaire-based and conducted in 2012 in Shiraz, the most populated city in the south of Iran...
