Laboratory Analysis of Split Ejaculates
From the works of Mac Leod and Hotchkiss in 19421 and Lundquist in 1949,2 it is generally accepted that during ejaculation in man, the accessory sex glands always secrete in the following order: Cowper’s glands, prostate, seminal vesicles. Epididymal fluid which contains the spermatozoa is liberated after release of prostatic fluid and is usually found highly concentrated in the first fraction of split ejaculate. One can therefore obtain a high concentration of male gametes to be used in artificial insemination by collecting this first fraction and thus eliminate problems associated with laboratory manipulation of the entire sample.
