Apart from the huge efforts made to develop an embryo in-vitro, the embryologist is faced with an even bigger task to choose an embryo from a cohort that will produce pregnancy. Selecting a single viable one is often a challenge to the embryologists and clinicians involved. This is because the one that is selected may determine outcome of the cycle. It is not in the embryologist interest to cho...

German embryologist Viktor Hamburger [4] came to the US in 1932 with a fellowship provided by the Rockefeller Foundation [5]. Hamburger started his research in Frank Rattray Lillie?s laboratory at the University of Chicago [6]. His two-year work on the development of the central nervous system [7] (CNS) in chick [8] embryos was crystallized in his 1934 paper, ?The Effects of Wing Bud Extirpatio...

In order obtain sample, patients have assist clinic where sample analyzed....

Abstract Study question Can embryologists and CHLOE-EQ predict ploidy? Does their confidence ability to vary with embryologist seniority? Summary answer High inter-observer variability between on prediction of ploidy. provided a consistent What is known already Previous studies have demonstrated the value using Artificial Intelligence (AI)-based tools, such as (Fairtility), support, quantify st...

In Poland, medical embryology (both scientific research and teaching of the subject) has traditionally involved Chairs of Histology and Embryology rather than Obstetrics and Gynecology. Before World War II, the most buoyant centers for embryological research among the five universities at the time (in Warsaw, Krakow, Poznan, Lvov and Vilnius), were the Chairs of Embryology and Histology at Medi...

In 1931 embryologist and historian Joseph Needham [3] published a well-received threevolume treatise titled Chemical Embryology [4]. The first four chapters from this work were delivered as lectures on Speculation, Observation, and Experiment [5], as Illustrated by the History of Embryology at the University of London. The same lectures were later released as a book published in 1934 titled A H...

Variations in course of the arteries are well documented. Knowledge of the variation of the arterial system is important during vascular and reconstructive surgeries, in the evaluation of angiographic images. During routine anatomical dissection of upper limb ,of adult male cadaver of 55 years in Department of anatomy, SNMC, Agra, we came across a variant origin of the ulnar artery, instead of ...

Sidnie Manton became best known for her work on arthropod locomotion, and for proposing radical views on the evolution of arthropods that were accepted for a generation. However, her early training was as an embryologist, and the work that she carried out at the beginning of her career still stands as one of the major twentieth century contributions to the study of crustacean embryology. Here, ...
