Debate The functional life span of the ovaries is dictated in large part by the number of oocytes present, a number that is known to decline precipitously during both fetal development and postnatal life. Furthermore, studies from numerous laboratories have shown that exposure of the ovaries to a variety of pathological insults, such as anticancer therapies and environmental toxicants, accelera...
background: repeated in vitro fertilization (ivf) failure together with ovarian hyperstimulation syndrome (ohss) is one of the distressing situations leading couples to search for alternative treatment options. for such patients with polycystic ovarian syndrome (pcos) who have experienced ovarian hyperstimulation syndrome, mild ovarian stimulation with in vitro oocyte maturation could be a prom...
The objective of this paper is to study the M/M/R machine repair queueing system with mixed standbys. The life-time and repair time of units are assumed to be exponentially distributed. Failed units are repaired on FCFS basis. The standbys have switching failure probability q (0≤q≤1). The repair facility of the system consists of R permanent as well as r additional removable repairmen. Due to i...
BACKGROUND Premature ovarian failure (POF) is generally irreversible. However, developing follicles up to the antral stage are reported in POF and anti-Müllerian hormone (AMH) might be a good indicator of follicular presence. This study analysed serum AMH, ovarian histology and AMH immunoexpression in POF patients. METHODS A cross-sectional study of 48 POF patients in an Endocrinology Departm...
