BACKGROUND Many variations in oocyte and embryo grading make inter-laboratory comparisons extremely difficult. This paper reports the proceedings of an international consensus meeting on oocyte and embryo morphology assessment. METHODS Background presentations about current practice were given. RESULTS The expert panel developed a set of consensus points to define the minimum criteria for o...

The Drosophila endoderm is patterned by the signals Decapentaplegic and Wingless secreted from the visceral mesoderm. This induction culminates in a precise pattern of spatially restricted expression of labial, a selector gene with a role in cell type specification in the larval midgut. Here, we show that Decapentaplegic signalling induces elevated expression of the Drosophila AP-1 transcriptio...

Abstract Reproductive efficiency and efficacy are key components of economic return in small ruminant production, therefore utilization assisted reproductive technologies has increased. Despite advances technologies, pregnancy rates per embryo culture transfer still remain low. The physio-chemical parameter pH within the female tract its potential implications success caprine remains to be eluc...

Background: Irisin is a recently identified myokine that acts like adipokines. It has been revealed to be connected with insulin resistance (IR), obesity, and metabolic syndrome. Objective: To investigate serum, follicular fluid (FF), irisin, IR in lean, overweight, obese women undergoing the intracytoplasmic sperm injection (ICSI) cycle correlate them oocyte embryo quality. Methods: Ninety inf...

Sir, We thank Benaglia et al. (2009) for their interesting study. In contrast to Nakagawa et al. (2008), they found that spontaneous ovulation is impaired in ovaries affected by endometriotic cysts. The same group previously observed hypo-responsiveness of the affected ovaries to gonadotrophin-induced controlled ovarian hyperstimulation (COH) (Somigliana et al., 2006a, b). In all studies, ovula...

assessment of embryo quality in order to choose the embryos that most likely result in pregnancy is the critical goal in assisted reproductive technologies (art). the current trend in human in vitro fertilization/embryo transfer (ivf/et) protocols is to decrease the rate of multiple pregnancies after multiple embryo transfer with maintaining the pregnancy rate at admissible levels (according to...

A 30 year old nulliparous woman, married for 7 years presented with complaints of lower abdominal pain since a year. Her menstrual history has been regular, associated dysmenorrhea. She gave past surgical right ovarian cystectomy in view chocolate cyst noted on diagnostic laparoscopy. Investigations revealed bilateral complex and an elevated Ca-125 100 units/ml, proceeded salphingo-oopherectomy...

Objective: Microfluidic channel system (MAC), a new generation method, gives the chance to select better quality spermatozoa with lower DNA fragmentation indices. This study evaluated treatment results in patients who underwent ICSI-ET due MAC technique's male factors.
 
 Methods: Sakarya University ART Center carried out this retrospective study. Patients 35 factor indications were i...

This paper investigates the relationship of features of in-vitro fertilization (IVF) embryos and the associated oocyte and follicle to the outcome of transfer. It differs from previous studies in including a range of features (n = 53) and in using class probability tree analysis. This is a non-parametric multivariate method which expresses relationships as simple rules of features characterizin...
