abstract
Isikhathi se-Lordosis se-hamster yegolide yowesifazane (Mesocricetus auratus) ukuphendula inoveli nabalingani abajwayelekile bokuzala. Ku -esera engu-1, izintokazi ziye zafika ezingeni lokuzanelisa ngokocansi nge-hamster eyodwa yowesilisa, nangemva kokukhishwa kwayo, zakhombisa ukuphinda kuvunyelwe ekuphenduleni ngenkathi kuqalwa owesilisa wesibili. Lapho kuhlukaniswa ngokobulili nowesilisa wesibili, abesifazane bathola inoveli yesithathu yenenekazi noma babuyiselwe kowesilisa wokuqala. Isikhathi sonke se-Lordososis kwibhomu lesithathu eqenjini elithola inoveli yesilisa sasisikhulu kakhulu kunaseqenjini elibekwe kabusha kowesilisa wokuqala.
Ekuhlolweni 2, ukufakwa kokulibaziseka okungu-1-h phakathi komlingani wesibili nowesithathu wokukhwelana akuzange kube nomthelela ekuphenduleni kwabesifazane, noma ngabe owesilisa wesithathu bekungowesilisa wokuqala noma owesilisa onoveli.
Ku-Experiment 3, ukususwa kwama-ovari kulandelwe ukwelashwa kwe-hormone replacement (40 micrograms estradiol benzoate, 72 h ngaphambi kokuhlolwa, kanye nama-500 micrograms progesterone, 4 h ngaphambi kokuhlolwa) kwehlulekile ukuguqula amandla abesifazane ukucwasa phakathi kwenoveli nokuhlangana okujwayelekile ophathina.
Le miphumela ikhombisa ukuthi izintokazi zenza ukucwaswa okucacile phakathi kwabalingani bomuntu ngamunye, ukuthi lokhu kungathinta ukuqashelwa ngokocansi futhi kuzoqhubeka ukukwenza kulandela ukulibaziseka okungenani kwe-1 h, nokuthi umphumela awuhambisani nokukhululwa kwe-ovarian steroid.
