6PPD-Q (6PPD-Quinone), a contaminant present in the environment and soil, is a derivative of the tire antioxidant N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD), which impairs the quality of spermatozoa in mice and induces impaired male fertility.

Estradiol (E2) is a naturally occurring steroidal sex hormone that is essential for female fertility and maintenance of secondary sexual characteristics. Estradiol upregulates IL-6 expression through estrogen receptor beta (ERβ).

Lupeol acetate is a derivative of Lupeol with anti-cancer, anti-inflammatory, anti-diabetic, anti-snake venom, anti-fertility effects and oral activity. It is able to inhibit rheumatoid arthritis by down-regulating inflammatory cytokines (TNF-α, IL-1β, MCP-1, COX-2, VEGF, granzyme B) and is cytotoxic to Hep-3B and A549 cells.

Quassin has female anti-fertility properties, possibly acting via inhibition of estrogen secretion.
