Fig 2. Variation in the concentration of Glutathione Peroxidase 5 (SP-GPX5) in seminal plasma among the three different portions of the boar ejaculate.

Fig 2

Box-whisker plot showing variation in the concentration of SP-GPX5 in the three-ejaculate portions: the first 10 mL of spermatozoa-rich ejaculate fraction (SRF, sperm-peak portion), the rest of SRF and the post-SRF of 15 ejaculates (one per boar). Boxes enclose the 25th and 75th percentiles; the line is the median; and the whiskers extend to the 5th and 95th percentiles. (a,b) indicate significant differences (P < 0.005) among ejaculate portions.
