Identify, by Lipidomics approaches, biochemical markers of fertility / infertility in sperm and seminal plasma linking the success or failure of the artificial insemination (IUI)

Analyze lipid profiles in samples of sperm and seminal plasma of three populations:

1. male sperm donors
2. men assigned to a program of assisted reproduction with normal sperm / slightly abnormal successfully in the IUI;
3. attached to a program of assisted reproduction with male semen Normal / slightly abnormal unsuccessfully in IUI

Establish partnerships between the composition of fatty acids, especially fatty acids polyunsaturated (PUFA) of the omega-3 (w3) series of samples analyzed parameterssemen and results of the IA to identify biochemical markers of fertility.

Assess markers found by checking the increase in the rate of success in the IA.

Patients who undergo cycles of artificial insemination with own semen. Donor semen samples are intended for cycles of artificial insemination of donor Once the technical and knowing the value of the ßhCG (indicating pregnancy hormone)determined up to a maximum of 4 treatments, the population for this study were divided into three groups
