The objective of the current study was to investigate the association between rapid motility of sperm and IVF outcome when ICSI is used for insemination of oocytes. The first IVF cycle of women up to age 42 were evaluated. Patients were classified in

There is evidence that follicle-maturing drugs, especially when used for controlled ovarian hyperstimulation for in vitro fertilization–embryo transfer (IVF–ET) purposes, may be associated with lower pregnancy rates following ET related to a host

An overview of various sperm tests is presented. The standard semen analysis obtained by most clinicians evaluating infertility usually consists of sperm concentration, percent motility, quality of motility, and sperm morphology. Unfortunately, unles

The hypo-osmotic swelling (HOS) test measures the functional integrity of the sperm membrane. Although, the sperm membrane is essential for the fertilization of oocytes, several clinical studies suggest that abnormally low HOS test scores do not pred

Some sperm specimens contribute to infertility not by impairing the fertilization process but by causing embryo implantation defects. One hypothesis is that a toxic factor attached to the sperm is transferred to the zona pellucida by the supernumerar

Purpose: To determine if production of the immunomodulatory protein, progesterone induced blocking factor (PIBF), requires merely progesterone or whether other factors made by the corpus luteum are required. Methods: The percentage of peripheral lymp

Although the transfer of fertilized donor oocytes is the most efficacious mode of conception for infertile women with hypergonadotrophism associated with incipient or apparent ovarian failure, there are many individuals who, for religious, ethical, o

A recent study suggested that oligoasthenozoospermia may be an etiologic factor for spontaneous abortion (SAB) after in vitro fertilization-embryo transfer (IVF-ET). However, IVF-ET with intracytoplasmic sperm injection (ICSI) did not seem to be asso

Cryopreservation of human sperm using present methods leads to a reduced fertility potential of the specimen. In many instances this prevents the successful fertilization of the female partner from the frozen-thawed specimens of males whose semen has

Several studies suggest that sperm withor =4% normal morphology (NM) using strict criteria are subfertile and IVF with ICSI may be needed. However, not all studies agree on the clinical importance of the use of NM with strict criteria. One study of m
