1. A method for determining the quality of a semen of a vertebrate animal, the method comprising:

  • measuring at least one absorption spectrum of a sample of said semen with a spectrometer;

    selecting a number n, with n≥

    4, of wave numbers σ

    j (j∈

    [1;

    n])
    where the wave numbers are spatial frequencies in the spectrum characteristic of semen of a breed or of species of said animal;

    determining from said at least one absorption spectrum of at least one of a value of the absorption Xj or a value of the second derivative of the absorption Xj

    (j∈

    [1;

    n])
    for each of said n wave numbers σ

    j (j∈

    [1;

    n])
    ; and

    calculating a non-return rate Y at a predefined number of days from at least one of said absorption values Xj or the second derivative of the absorption Xj

    previously determined.
