What Are Blastocysts Embryos?In the IVF lab, fertilization occurs through conventional IVF (in vitro fertilization), or ICSI (Intra Cytoplasmic Sperm Injection) after egg retrieval. The resulting embryos are placed in an incubator for further development.The stages of development are as follows:Day 0: Egg retrieval day (IVF or ICSI is performed after egg retrieval).Day 1: Pronuclear stage.Day 2: Two to four-cell stage.Day 3: Eight-cell stage.Day 4: Morula stage.Day 5 or 6: Blastocyst stage.During the blastocyst stage, cells divide rapidly, forming the Inner Cell Mass (ICM) and Trophectoderm cells (TE). A mature blastocyst can contain up to 200 to 300 cells. The Inner Cell Mass (ICM), or embryoblast, is a crucial structure in the initial stages of embryonic development. It holds the potential to develop into the fetus's definitive structures. The inner cell mass formation occurs in the early phases of embryonic development before the embryo's implantation into the uterus'...
TECHNIQUES OF HUMAN SPERM CRYOPRESERVATIONCurrently, the most common method for preserving human sperm is cryopreservation. Cryopreservation is a physical process that involves using low temperatures to suspend biochemical reactions and metabolic activities in cells, to preserve cell structure and function. As a result, cells can be preserved for a very long time2. Currently, there are two common methods of cryopreservation of spermatozoa: slow freezing and vitrification.Besides the benefits of cryopreservation, freezing as well as thawing produces major changes in the cell that have a negative impact on cell viability and function tissue. The cooling process leads to the freezing of intracellular and extracellular water, thereby increasing the concentration of solutes in the remaining liquid phase. This leads to an osmotic imbalance between the cell and the environment, water from the cytoplasm is drawn out, the cell shrinks, and if the cell is too small, damage to the lipo...
The global ivf devices and consumables market was valued at $2.2 billion in 2022, and is projected to reach $12 billion by 2032, growing at a CAGR of 18.4% from 2023 to 2032. The growth of the IVF devices and consumables market is driven by a rise in prevalence of infertility, technological advancements in IVF devices, and increase in trend of delayed pregnancies. For instance, according to the World Health Organization (WHO) in 2022, around 17.5% of the adult population suffer from infertility across the globe.Key TakeawaysBy product, the accessories and disposables segment dominated the global market in 2022.By technology, the fresh embryo IVF segment dominated the global market in 2022.By end user, the fertility clinics segment dominated the market in terms of revenue in 2022.By region, Asia-Pacific dominated the market share in terms of revenue in 2022 and is anticipated to grow at the highest CAGR during the forecast period.In vitro fertilization (IVF) is a comprehensive fertility...
