BACKGROUND: The use of in vitro fertilization that includes third-party in vitro fertilization is increasing. However, the relative contribution of third-party in vitro fertilization that includes the use of donor oocytes, sperm, or embryo and a gestational carrier to the birth cohort after in vitro fertilization is unknown. OBJECTIVE: The purpose of this study was to examine the contribution of third-party in vitro fertilization to the in vitro fertilization birth cohort over the past decade...

Implantation rate decreases and miscarriage rate increases with advancing maternal age. The oocyte must be the locus of reproductive aging because donation of oocytes from younger to older women abrogates the effects of aging on fecundity. Nuclear transfer experiments in a mouse model of reproductive aging show that the reproductive aging phenotype segregates with the nucleus rather than the cytoplasm. A number of factors within the nucleus have been hypothesized to mediate reproductive aging, including disruption of cohesions, reduced chiasma, aneuploidy, disrupted meiotic spindles, and DNA damage caused by chronic exposure to reactive oxygen species...

With the introduction of oocyte vitrification, a special form of intergenerational intrafamilial medically assisted reproduction (IMAR) has now become feasible: fertility preservation for mother-to-daughter oocyte donation (FPMDD). For girls diagnosed with premature ovarian insufficiency (POI), banking of their mothers' oocytes can preserve the option of having genetically related offspring. Since policy documents on IMAR do not discuss specific concerns raised by FPMDD, clinicians can feel at a loss for guidance with regard to handling these requests...

OBJECTIVE: To investigate whether thrombomodulin dysregulation is involved in the development of preeclampsia after oocyte donation (OD). Women who become pregnant after OD are prone to develop preeclampsia, a syndrome characterized by an aberrant immunologic response, hypercoagulability, and endothelial dysfunction. A mediator of inflammation and coagulation is thrombomodulin, which has a possible role to play in this syndrome. DESIGN: Case-control study. SETTING: Not applicable...

BACKGROUND: Pregnancies resulting through oocyte donation have been associated with increased risk for adverse outcomes for the mother, such as gestational hypertensive disorders. However, little is known about possible neonatal complications of such pregnancies. The purpose of this study was to evaluate the neonatal health outcomes among singleton pregnancies in a population of relatively young and healthy oocyte recipients in Sweden, taking into account the medical indication leading to treatment...

PURPOSE: To identify the utility and issues associated with the use of decision trees in oncofertility patient care in Japan. METHODS: A total of 35 women who had been diagnosed with cancer, but had not begun anticancer treatment, were enrolled. We applied the oncofertility decision tree for women published by Gardino et al. to counsel a consecutive series of women on fertility preservation (FP) options following cancer diagnosis. Percentage of women who decided to undergo oocyte retrieval for embryo cryopreservation and the expected live-birth rate for these patients were calculated using the following equation: expected live-birth rate = pregnancy rate at each age per embryo transfer × (1 - miscarriage rate) × No...

BACKGROUND: Ovarian failure (OF) is considered premature if it occurs before the age of 40. This study investigates the genetic aetiology underlying OF in women under the age of 40 years. METHODS: We conducted an experimental prospective study performing all genome microarrays in 60 patients younger than 40 years presenting an OF revealed by a decrease of circulating Anti-Müllerian Hormone (AMH) and leading to an oocyte donation program. RESULTS: We identified nine significant copy number variations (CNVs) including candidate genes potentially implicated in reproductive function...

PURPOSE OF REVIEW: Utilization of cryopreserved instead of fresh donor oocytes has rapidly increased in recent years. Whether treatment outcomes are comparable has, however, remained controversial. RECENT FINDINGS: More than 24% of initiated oocyte donation cycles in the USA during 2013-2014 involved previously cryopreserved oocytes. The use of cryopreserved-donated oocytes may simplify logistics and lower costs per treatment cycle. Whether cryopreserved donor oocytes also lower costs per live birth is still undetermined as they result in lower live birth rates in comparison to fresh donor oocyte cycles...

Time-lapse imaging offers new tools to study dynamic processes of development such as blastocyst formation and expansion. This study quantitatively describes expansion in human blastocysts from donated oocytes. Measurements of hourly interval rate of changes in the blastocoel cross-sectional area revealed oscillatory pulses having 2-4 h periodicities. Two types of oscillations were distinguished. An E-Type ('expansion') had positive peak and positive or slightly negative trough interval rate of change values, and these characterized most of the expansion period...

Turner syndrome (TS) occurs in one in 2500 live female births and is one of the most common chromosomal abnormalities in women. Pregnancies in women with TS, conceived with either autologous or donated oocytes, are considered high risk because of the associated miscarriages and life-threatening cardiovascular complications (aortic dissection, severe hypertension). Therefore, it is imperative to conduct a full preconception evaluation and counselling that includes cardiac assessment with Holter blood pressure monitoring, echocardiography, and thoracic MRI...

The oocyte quality is to a large extent influenced by the sexual maturity of the donor female. Although this phenomenon has already been broadly described in domestic animals, the underlying mechanisms are poorly understood. Published data focus on oocyte ultrastructure, fertilization abnormalities, and blastocyst developmental rate. The goal of the present experiment was to characterize the follicular environment (oocyte, cumulus [CC] and granulosa (GC) cells as well as follicular fluid [FF]) in ovarian follicles of prepubertal heifers and cows...

STUDY QUESTION: Does switching to donor semen after at least three failed oocyte donation (OD) cycles with the partner normozoospermic semen increase the live birth rate in a subsequent OD cycle? SUMMARY ANSWER: Switching to donor semen after at least three failed OD cycles with the partner normozoospermic semen does not increase the live birth rate. WHAT IS ALREADY KNOWN: In some patients, a viable pregnancy cannot be achieved after several OD cycles, despite normal diagnostic findings for the couple...

BACKGROUND: Approximately 50 000 oocyte donation (OD) treatment cycles are now performed annually in Europe and the US. OBJECTIVES: To ascertain whether the risk of adverse obstetric and perinatal/neonatal outcomes is higher in pregnancies conceived by OD than in pregnancies conceived by conventional in-vitro fertilisation (IVF)/intracytoplasmic sperm injection (ICSI) or spontaneously. SEARCH STRATEGY: A systematic search was performed in the PubMed, Cochrane and Embase databases from 1982-2016...

INTRODUCTION: Turner syndrome (TS) is associated with subfertility and infertility. Nevertheless, an increasing number of women become pregnant through oocyte donation. The wish to conceive may be negatively influenced by the fear of cardiovascular complications. The aim was to investigate the wish to conceive and the concerns about cardiovascular complications during pregnancy in women with TS. METHODS: The patient association for TS invited all members of ≥18 years old (n = 344) to complete a specifically developed, disease-specific questionnaire, including questions about fertility, wish to conceive, attempts and concerns...

UNLABELLED: Chromosomal polymorphisms involve heterochromatic regions and occur in the general population. However, previous studies have reported a higher incidence of these variants in infertile patients. The aim of this study was to examine the relationship between polymorphic variants and infertility and their association with aneuploidies in male gametes and embryos. We retrospectively considered 1,551 cytogenetic studies involving infertile patients (study group; n=866) and oocyte/sperm donors as the control group (n=685)...
