New Structure Discovered in Human Sperm Tails

New Structure Discovered in Human Sperm Tails

Sperm are essential for reproduction. Normal sperm parameters (count, motility and morphology) are important for fertilization to occur following intercourse. In order for sperm to be motile, a highly effective sperm tail is needed to propel the sperm though the cervix and uterus into the fallopian tube to find the ovulated egg. A new structure […]

Egg Freezing | Fertility Preservation | FCNE

Women are born with a finite number of eggs which continuously decline from birth. As women age the quality of these eggs also declines leading to fewer successful pregnancies and more chromosomally abnormal pregnancies and miscarriages. The concept of  ‘fertility preservation’ arose from trying to halt the ‘biologic clock’ by freezing eggs until such time […]

Preimplantation Genetic Testing

preimplantation genetic diagnosis

In this five part series preimplantation genetic testing is defined and the categories of genetic disorders that preimplantation genetic testing may identify are described. Preimplantation genetic testing for diagnosis is referred to as PGD and is used to identify specific chromosomal or genetic defects in embryos created though in vitro fertilization (IVF) and intracytoplasmic sperm […]
