Peroxiredoxin 5 (PRDX5) is an important peroxiredoxin with antioxidant and antiapoptotic functions. The objective of this study was to determine whether the antioxidant and antiapoptotic activities of PRDX5 play an essential role in the in vitro development of bovine SCNT embryos. We analyzed the expression patterns of PRDX5, and found the expression of PRDX5 in second meiotic metaphase oocytes, which persisted until the blastocyst stage IVF and SCNT embryos. In addition, PRDX5 transcript levels were significantly higher in SCNT embryos than those in IVF embryos...

This work was designed to study whether viscous media can improve the in vitro sperm functionality in pigs by using methylcellulose as a thickener. Viscosity of porcine oviductal fluid (POF) was compared with culture medium (Tyrode's) supplemented with methylcellulose (MET 0, 0.5 and 1% w/v). Spermatozoa were incubated in the different media (0, 1 and 2 h) and sperm motion parameters, lipid membrane disorder, plasma membrane integrity and reactive oxygen species (ROS) formation were assessed. Fertilization results were assessed i) preincubating spermatozoa in the viscous media followed by gamete coculture in a non-viscous medium; and ii) gamete coculture in the viscous media...

We report that the Gm7068 (CatSperε) and Tex40 (CatSperζ) genes encode novel subunits of a 9-subunit CatSper ion channel complex. Targeted disruption of CatSperζ reduces CatSper current and sperm rheotactic efficiency in mice, resulting in severe male subfertility. Normally distributed in linear quadrilateral nanodomains along the flagellum, the complex lacking CatSperζ is disrupted at ~0.8 μm intervals along the flagellum. This disruption renders the proximal flagellum inflexible and alters the 3D flagellar envelope, thus preventing sperm from reorienting against fluid flow in vitro and efficiently migrating in vivo...

Propagating genetically valuable individuals through oocyte collection, in vitro fertilization (IVF) and embryo transfer is critical to maintain sustainable populations of the endangered Eld's deer. The objectives of this study were to assess the impact of exogenous FSH injections on (1) the number and in vitro competence of oocytes collected and (2) the developmental potential of resulting IVF embryos after transfer into recipients during the breeding season (February-April). In a pilot experiment, estrus synchronization was conducted in three surplus females (using intravaginal progesterone-releasing devices, CIDRG for 14 days and injections of buserelin (a GnRH agonist)...

GnRH agonist (GnRHa) trigger for final oocyte maturation in GnRH antagonist co-treated IVF/ICSI cycles significantly reduces the risk of ovarian hyperstimulation syndrome (OHSS). GnRHa trigger followed by modifications of the standard luteal phase support (modified luteal phase support) secures fresh transfer in the majority of patients with excellent reproductive outcomes. In freeze all cycles (segmented cycles) GnRHa trigger allows oocyte retrieval with a minimal risk of early onset OHSS and good reproductive outcomes in subsequent frozen thaw cycles...

BACKGROUND: Although the increased risk for perinatal morbidity and mortality of babies born after ART is largely attributed to a higher rate of multiple gestations, a significantly worse perinatal outcome for singleton pregnancies following ART compared to pregnancies after natural conception has been reported as well. Most studies only include IVF/ICSI pregnancies; studies describing the perinatal outcome of pregnancies after non-IVF assisted reproduction are scarce. METHODS AND MATERIALS: Population-based cohort study with three exposure groups: a study group of pregnancies (1) after ovarian stimulation (OS), with or without artificial insemination (AI), (2) after IFV or ICSI and (3) a naturally conceived (NC) comparison group...

The epidemic of iatrogenic multiple births as a result of infertility treatment are responsible for an unacceptable high incidence of maternal, perinatal and childhood morbidity and mortality. Healthcare costs due to infertility therapy are too high and this may lead to social and political concern. The introduction of single embryo transfer (SET) was a real breakthrough, but was only accepted in most European countries and Japan. The United States, Latin America and most developing countries still have high multiple pregnancy rates...

Special considerations must be taken when patients with human immunodeficiency virus (HIV), Hepatitis B, or Hepatitis C desire to achieve pregnancy. Patients with chronic viral illnesses desire children at rates similar to the general population, and options are available to decrease both vertical transmission and viral transmission between partners. Preconception counseling or consultation with fertility specialists is imperative in patients with HIV, Hepatitis B, and Hepatitis C so that reproductive goals can be addressed and optimized...

Infertility treatments remain expensive and in many countries are covered by little, if any, insurance, raising critical questions concerning how patients and providers view and make decisions regarding these challenges. In-depth semi-structured interviews of approximately 1 hour were conducted with 37 IVF providers and 10 patients (17 physicians, 10 other providers and 10 patients), and were systematically analyzed. These data suggest current insurance policies and legislation pose critical ethical and logistical challenges for both patients and providers...
