The present randomized controlled in vitro study was designed to evaluate the effects of the exposure of human cryopreserved oocytes to endometriotic fluid. Twenty-three women aged 36 (4) years donated a total of 147 vitrified supernumerary metaphase II oocytes. Warmed oocytes were randomly assigned to exposure to endometriotic fluid or unexposed control. Thereafter, oocytes were parthenogenetically activated and cultured for up to 5 days. The rate of activation on day 1 and the developmental rates on days 3 and 5 did not significantly differ between the 2 groups...

BACKGROUND: The demand for donor oocytes has increased dramatically over the years. Today people in need of ART with the use of donor oocytes can appeal to commercial or public donor oocyte banks. The introduction of oocyte banks has shed a new light on the practice of ART using donor oocytes. The establishment and maintenance of oocyte banks should be sensitive to the ethical considerations. However, it is currently unclear which ethical aspects have to be taken into account. OBJECTIVE AND RATIONALE: The aim of this article is to identify the ethical aspects of establishing and maintaining oocyte banks for third-party ART...

Benign hydatidiform mole, complete or partial, is the most common type of gestational trophoblastic disease (GTD) characterised by excessive trophoblastic proliferation and abnormal embryonic development. Although most complete hydatidiform moles (CHMs) are diploid androgenetic, a few cases of CHMs are biparental, characterised by recurrence and familial clustering. In these rare cases, mutations in NLRP7 or KHDC3L genes, associated with maternal imprinting defects, have been implicated. Current data regarding future pregnancy options in hydatidiform moles are discussed and our opinion is presented based on an incidence that took place in our hospital with a woman with consecutive molar pregnancies...

Classic galactosemia is a rare inherited disorder of galactose metabolism. Primary ovarian insufficiency (POI) with subfertility affects > 80% of female patients and is an important concern for patients and their parents. Healthcare providers are often consulted for subfertility treatment possibilities. An option brought up by the families is intrafamilial oocyte donation (mother-to-daughter or sister-to-sister). In addition to POI, galactosemia patients can also present varying cognitive and neurological impairments, which may not be fully clear at the time when mother-to-daughter oocyte donation is considered...

Mutant mitochondrial DNA gives rise to a broad range of incurable inborn maladies. Prevention may now be possible by replacing the mutation-carrying mitochondria of zygotes or oocytes at risk with donated unaffected counterparts. However, mitochondrial replacement therapy is being held back by theological, ethical, and safety concerns over the loss of human zygotes and the involvement of a donor. These concerns make it plain that the identification, validation, and regulatory adjudication of novel embryo-sparing donor-independent technologies remains a pressing imperative...

This article begins with the story of a 51-year-old Los Angeles, California man, Justin Goldberg, whose daughter caught a glimpse of his striking look-alike at a popular market. Many people have so-called doppelgängers, but this occurrence is especially intriguing - the individual in question, born in New York City in the mid-1960s to an unwed mother, was an adoptee placed by the Louise Wise Adoption Agency. This agency, under the guidance of a prominent psychiatrist, decided to place twins in separate homes...

In a possible first, the heritable transmission of a fatal mitochondrial DNA disease (Leigh syndrome) may have been prevented by replacing the mutation-bearing mitochondria of oocytes with donated mutation-free counterparts. The procedure, carried out by a U.S.-led team, took place in Mexico in circumvention of a statutory U.S. moratorium on mitochondrial replacement. This development calls into question the regulatory utility of a national moratorium in a globalized world wherein cross-border care is increasingly prevalent...

Background and Objective: Administration of growth hormone (GH) during ovarian stimulation has been shown to improve success rates of in vitro fertilization. GH beneficial effect on oocyte quality is shown in several studies, but GH effect on uterine receptivity is not clear. To assess it, we studied whether GH administration can improve the chance of pregnancy and birth in women who experienced repeated implantation failure (RIF) using donated oocyte programs. Design and Study Population: A total of 105 infertile women were enrolled in the randomized controlled trial: 70 women were with a history of RIF with donated oocytes, and 35 infertile women underwent the first oocyte donation attempt...
