Complete understanding of the route of HIV-1 transmission is an important prerequisite for curbing the HIV/AIDS pandemic. So far, the known routes of HIV-1 transmission include sexual contact, needle sharing, puncture, transfusion and mother-to-child transmission. Whether HIV can be vertically transmitted from human sperm to embryo by fertilization is largely undetermined. Direct research on em...

This work was designed to study how this ability is affected by different sperm treatments routinely used for in vitro fertilization (IVF) assay. In this study, boar sperm samples from epididymal or ejaculated origin were processed by three different methods: left unwashed (NW group), washed in Dulbecco's phosphate-buffered saline supplemented with 0.1% BSA (BSA group), and washed on a Percoll(...

Gold containing Ayurvedic preparation, Swarna Vasant Malti, was given to 20 male persons in a dose of 100 mg twice a day for 40 days under supervision of Ayurvedic physicians. The total cumulative intake of 160 mg of gold at the rate of 4 mg per day in this form did not have any toxic effect on human body as evidenced by clinical examination, unaltered body weight, absence of urinary pathology ...

Frozen-thawed (FT) embryo transfer is a procedure used for the storage and transfer of excess embryos obtained during in vitro fertilization- intracytoplasmic sperm injection cycles. In recent years, improvements in laboratory conditions and limitations on the number of embryos to be transferred have led to a progressive increase in FT embryo transfer cycles. However, the best solution for endo...

Abstract Study question In men with Raised Sperm DNA Fragmentation Index (DFI), Would advance sperm preparation techniques at Intra-Cytoplasmic Injection (ICSI) alter embryo euploidy status? Summary answer raised DFI, use of selection are safe and do not appear to ploidy status the embryos What is known already MACS (Magnetic Activated Cell Sorting), Microfluidic Sorting (MF), surgically retrie...

introduction: the acrosome is a sac shaped organelle contaning lysosomal enzyme that is located on the anterior of sperm head. during the acrosome reaction its content is released in the vicinity of the egg. the acrosome reacted sperm then penetrates through the egg barriers. there are several methods for evaluating the acrosomal status; some of those are complex, expensive and/or non-accurate ...
