Fig. 4: Composition of seminal proteins transferred by ThaiWolb and Thai males.

Volcano plots showing the abundance of all proteins identified in Thai and ThaiWolb ejaculates (a), seminal proteins classified as SFPs (b), sperm proteins (c), and sperm/SFP overlapping proteins (d). Values below zero represent proteins with higher abundance in ThaiWolb male ejaculates, and values above zero represent proteins with higher abundance in Thai male ejaculates.
