Accurate assessment of embryos viability is an extremely important task in the optimization of in vitro fertilization treatment outcome. One of the common ways of assessing the quality of a human ...embryo is grading it on its fifth day of development based on morphological quality of its three main components (Trophectoderm, Inner Cell Mass, and the level of expansion or the thickness of its Zona Pellucida). In this study, we propose a fully automatic method for segmentation and measurement of TE region of blastocysts (day-5 human embryos). Here, we eliminate the inhomogeneities of the blastocysts surface using the Retinex theory and further apply a level-set algorithm to segment the TE regions. We have tested our method on a dataset of 85 images and have been able to achieve a segmentation accuracy of 84.6% for grade A, 89.0% for grade B, and 91.7% for grade C embryos.
The paper explains basic ways of functioning of private law instruments aimed at financing in vitro fertilization, expansion of which goes hand to hand with the progress of reproductive medicine. In ...addition to state (public) instruments of financing the costs of in vitro fertilization (IVF) procedure, comparative practice has experienced a development of private law instruments for covering such expenses. These instruments are offered by insurance companies, other financial organizations (funds which are established with particular purpose) or clinics (often consortium of clinics) which practice in vitro fertilization. The most common among them are: 1. Private health insurance which covers the expenses incurred in connection to IVF procedure; 2. The program of refund (return) of most (80 to 90 percent) or all (100 percent) of the expenses of IVF after a number of unsuccessful procedures (known under different titles such as: money-back guarantee program, shared-risk, success-based risk sharing plan, IVF success guarantee program, the IVF baby guarantee or your money back plan, pregnancy guarantee program etc. ); 3. Packages contained of a number of procedures - cycles for lower price (packages of 2, 3 or 4 ivf cycles). Programs such as these increase the level of reproductive medicine's usability. Since the programs are not yet applied in Serbia, the paper explains basic mechanisms of their functioning in comparative law.

Conventional IVF Insemination Nel-Themaat, Liesl; Elliott, Thomas; Chang, Ching-Chien ...
Practical Manual of In Vitro Fertilization
Book Chapter
Our objective with this chapter is to give a brief overview of the conventional in vitro fertilization (IVF) procedure and some of the factors that determine success. The decision-making process of ...whether to do conventional IVF, intracytoplasmic sperm injection (ICSI), or split-ICSI is very complex. We present the influencing factors in a manner that allows thorough evaluation of every case, resulting in an educated, well thought through decision of which insemination method to use. We believe it will assist embryologists in deciding which method of fertilization to use in their labs.
