Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In the recent years, there is an increasing tendency to the parenthood delay in developed countries, and there is not enough information available regarding the influence of the male's age on fertility. If any, the negative impact should be acting at advanced ages.

Our aim with this work was to determine the role of paternal age on IUI results embryo quality and IVF outcome. Evenmore, in order to standardize the female factor, good quality oocytes (from fertile oocyte donors) and only first IVF cycles in young women were considered.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A retrospective study has been designed with a total number of 2204 IUI, 1286 IVF cycles and 1412 IVF cycles with donated oocytes from 2000 to 2006.

The inclusion criteria will be for IUI: women under 38 years old, tubal patency demonstrated by hysterosalpingography, normal uterine scan, normal basal hormonal levels, body mass index \< 27 kg/m2, and absence of polycystic ovarian syndrome and endometriosis. For normal IVF cycles and oocyte donation cycles only first cycles will be analyzed. Cycles will be studied only in couples with absence of severe male factor.
