Sperm Selection for Infertility Treatment (SSA)

2016-08-16 10:08:21 | BioPortfolio


Infertility is considered a disease by the World Health Organization, and it is increasing worldwide, affecting more than 70 million couples. About 50% of the cases are due to male inability to fertilize the oocyte. In the last 40 years, several techniques, known as Assisted Reproduction Technology (ART) have been developed to treat infertility, but the efficiency is still relatively low (around 30% of success) whereas the remaining 70% attempts again several times, an expensive and emotionally moving treatment. Over 4million of infertility treatments are practiced around the world per year and a 50% increment is expected over the next 6years. Even though ART allows the birth of babies that would be impossible under natural circumstances, it is still necessary to improve the procedures in order to increase treatment efficiency. The success of ART depends, to some extent, on sperm quality. Indeed, the relevance of spermatozoa quality is notorious even beyond fertilization, extending to embryo development and implantation. In this context, it has been developed a new technology that allows the selection of those spermatozoa at their best functional state (Sperm Selection Assay, SSA; Patent approved for USA and Europe, pending for Japan and Argentina). This method is based on the attraction of spermatozoa ready to fertilize the egg, towards a physiological attractant molecule. The SSA may be applied to improve diagnosis and infertility treatment. The investigators hypothesis states that the use of the SSA will improve the number of good-quality embryos which are the ones to be transferred by intracytoplasmic sperm injection (ICSI), providing a healthy embryo development. The protocol involves three experimental groups where the SSA will be used or not, before performing the ICSI: 1)SSA containing the sperm attractant molecule, 2)SSA without the attractant molecule, and 3)without SSA. The patient inclusion criteria involve female factors associated to tubal obstruction and/or endometriosis and male factors associated to sperm disability. Several outcome parameters will be determined, the percentage of fertilization, embryo quality, rate of pregnancy and rate of birth. The study will be carried out in the Universitarian Institute of Reproductive Medicine (IUMER) which has been recently established in a public hospital depending on the National University of Córdoba, offering free high complexity infertility treatment to patients without health insurance or economic support

Medical and Biotech [MESH] Definitions

An assisted fertilization technique consisting of the microinjection of a single viable sperm into an extracted ovum. It is used principally to overcome low sperm count, low sperm motility, inability of sperm to penetrate the egg, or other conditions related to male infertility (INFERTILITY, MALE).

The quality of SEMEN, an indicator of male fertility, can be determined by semen volume, pH, sperm concentration (SPERM COUNT), total sperm number, sperm viability, sperm vigor (SPERM MOTILITY), normal sperm morphology, ACROSOME integrity, and the concentration of WHITE BLOOD CELLS.

Interactive processes between the oocyte (OVUM) and the sperm (SPERMATOZOA) including sperm adhesion, ACROSOME REACTION, sperm penetration of the ZONA PELLUCIDA, and events leading to FERTILIZATION.

The species Physeter catodon (also called Physeter macrocephalus), in the family Physeteridae. The common name is derived from the milky wax substance in its head (spermaceti). The species also produces an intestinal secretion AMBERGRIS, which was previously used in perfumes. The sperm whale is the largest toothed MAMMAL in the world.

A gray substance found in the GASTROINTESTINAL TRACT of the SPERM WHALE.
