Maikutlo: Li-receptor tse tšoanang tsa dopamine tse fokotsehang ka lithethefatsi (D2) ke tsona tse ka sehloohong tse amehang ka libido le likhetho. Basebelisi ba bang ba boima ba litšoantšo tsa bootsoa ba tlaleha ho se sebetse ha erectile, e kanna ea ba ka lebaka la "ho fokotsa meputso ea bona," e amanang le ho theoha ha li-receptor tsa bohlokoa tsa dopamine.

Tšebeliso ea D1 / D2 dopamine receptor agonist apomorphine bakeng sa phekolo ea ho se sebetse ha erectile e fana ka tšehetso e matla bakeng sa ho kenya letsoho tsamaisong ea dopaminergic ho laola mokhoa oa thobalano.
Leha ho le joalo, ha ho tsejoe hore na ho kenyelletsoa ha dopamine hakae ho laola takatso ea ho kopanela liphate le ho tsoaloa ha thobalano ho banna. Tlhahlobo ea lits'ebetso tsa litoeba tsa banna e fana ka maikutlo a ho ba le dopamine ka tšusumetso ea thobalano hammoho le ts'ebetso ea ho kopitsa. Liteko tse khethehileng tse lumellanang le ts'oaetso ea thobalano li bontšitse hore ho lokolloa ha dopamine boemong ba nucleus accumbens (ho sa hlokomeloe ke tsela ea maonolimbic dopaminergic) le sebaka se ka pele sa hypothalamus (se sa hloekisoang ke dopaminergic incertohypothalamic path) se laoloang hantle ho lebelloa / ho susumetsa mohato oa boitšoaro bo hlephileng. Karolo ea ho lumella motho hore a amohelehe ka mokhoa o lumellanang le lefu la dopamine e lokolitsoeng boemong ba sebaka se bohareng sa hypothalamus se bontšang boitšoaro bo kopanetsoeng se boetse se bontšitsoe. Hoa hlokomeleha hore likarolo tsena tsa tsamaiso ea dopaminergic ha li totobetse ka mokhoa oa ho kopanela liphate empa ho e-na le hoo li bonahatsa ho ameha ha dopamine ka taolo ea ts'ebetso ea mohopolo, ea bohlokoa le ea moputso. Ka lebaka la karolo ea eona ho laola mosebetsi oa ho lokisa, botšepehi ba tsela ea nigrostriatal dopaminergic bo boetse boa hlokahala bakeng sa pontšo ea boitšoaro bo hlephileng.
Ka tsela e itseng ka ho khetheha ho sebetsa ka thobalano, ho ka 'na ha etsahala hore dopamine e ka etsa hore penile erection e sebetse ka li-neuronic oxytocinergic tse ka tlas'a mokokotlo oa hypothalamus,' me mohlomong ho na le khalase ea pro-erectile sacra parasympathetic ka hare ho mokokotlo. Qetellong, dopamine e bohareng ke neurotransmitter ea bohlokoa ho laola mokhoa oa thobalano.
