BACKGROUND: One in four pregnancies end in a pregnancy loss. Although the effect on couples is well documented, evidence-based treatments and prediction models are absent. Fetal aneuploidy is associated with a higher chance of a next successful pregn

Meiosis, a key process in the creation of haploid gametes, is a complex cellular division incorporating unique timing and intricate chromosome dynamics. Abnormalities in this elaborate dance can lead to the production of aneuploid gametes, i.e., eggs

Meiotic recombination is sexually dimorphic in most mammalian species, including humans, but the basis for the male:female differences remains unclear. In the present study, we used cytological methodology to directly compare recombination levels bet

Failure of homologous chromosomes to recombine is arguably the most important cause of human meiotic nondisjunction, having been linked to numerous autosomal and sex chromosome trisomies of maternal origin. However, almost all information on these "e
This protocol outlines the generation of metaphase spreads of a single oocyte at either the immature metaphase I (MI) or mature metaphase II (MII) stage. This protocol utilizes formaldehyde fixation and therefore allows for further immunofluorescence

Summary Chromosome segregation errors during female meiosis are a leading cause of pregnancy loss and human infertility. The segregation of chromosomes is driven by interactions between spindle microtubules and kinetochores. Kinetochores in mammalian

We describe the collection, culture, and ex vivo, in vitro maturation of germinal vesicle (GV) oocytes obtained from human small antral follicles (hSAFs). hSAFs contain fully grown GV oocytes and have the advantages that they are more numerous than l
