Amamodeli ayi-10 ahlelwe ukukhombisa ubudlelwano phakathi kwenqubo yokukhula kwengane kanye nesibeletho ngokukhulelwa kuka-Okthoba. Iqanda libizwa ngokuthi likhulelwe noma livundisiwe zingakapheli amasonto ama-2 ngemva kokukhulelwa; Amasonto ama-3-8 ngemva kokukhulelwa abizwa ngokuthi ama-embryo; Kusukela ekupheleni kwesonto lesi-8, libizwa ngokuthi i-fetus; amasonto ayi-8; I-embryo icishe ibe ngu-3cm ubude futhi isiqalile ukuthatha isimo somuntu, inekhanda elikhulu kakhulu, amehlo abonakalayo, izindlebe, impumulo nomlomo. Ukwakheka kwenhliziyo yokuqala kanye nokushaya kungatholakala ngokuhlolwa kwe-ultrasound. Emasontweni ayi-12, ingane ingama-7 ~ 9cm ubude futhi inesisindo esingama-20g. I-orthogonia yangaphandle ivele, kukhona umsebenzi obuthakathaka ezithweni, futhi izikhungo zokwakheka kwezicubu zivele emathanjeni amaningi. Emasontweni ayi-16, ingane ingama-10 kuya ku-17cm ubude futhi inesisindo esingama-100 kuya ku-120g. Inesikhumba esibomvu, esibushelelezi nesicacile esinezinwele ezincane ze-vellus. Ukuthuthukiswa okwengeziwe kwamathambo, ukuhlolwa kwe-X-ray kungabona isithunzi samathambo, i-straightener yangaphandle ingahlukanisa owesilisa nowesifazane. Ukuhlolwa kwesisu kungezwa umsindo wenhliziyo yengane, abesifazane abakhulelwe bangazizwa ukunyakaza kwengane. Emasontweni angama-20, ingane ingama-18 ~ 27cm ubude, inesisindo esingu-280 ~ 300g, isikhumba sibomvu ngokumnyama, ukucaca kuyancipha, umzimba unamafutha engane, ikhanda lengane libalelwa ku-1/3 yomzimba, kukhona ukukhula kwezinwele, futhi umsebenzi wokugwinya uqala. Emasontweni angama-24 ubude bomzimba wengane bungama-28 ~ 34cm, isisindo singu-600 ~ 700g, amafutha angaphansi kwesikhumba aqala ukwakheka, imibimbi yesikhumba. Emasontweni angama-28, ingane ingama-35 ~ 38cm ubude futhi inesisindo esingu-100 ~ 1200g. Umzimba wonke mncane, isikhumba sibomvu, kukhona amafutha engane emunweni (uzwane) uzipho alufinyeleli ekugcineni komunwe (uzwane). Kwabesifazane, i-labia majora iqukethe i-labia minora kanye ne-clitoris, kanti emadodeni, amasende ehlele esinqeni. Ngenxa yamafutha angaphansi kwesikhumba amancane, imibimbi yobuso, njengendoda endala. Uma zizalwa, zingakhala, zigwinye, futhi zinyakazise imilenze yazo, kodwa zibuthakathaka futhi zidinga ukunakekelwa okukhethekile ukuze ziphile. Ingane yamasonto angu-32 inobude obungu-40cm, inesisindo esingu-1500 ~ 1700g, isikhumba sibomvu ngokumnyama, uboya bobuso buwile, futhi bungasinda ngemva kokunakekelwa okufanele. Emasontweni angu-36, ingane inobude obungu-45 ~ 46cm futhi inesisindo esingaba ngu-2500g. Amafutha angaphansi kwesikhumba, imibimbi yobuso iyanyamalala, uzipho lomunwe (uzwane) lufinyelele umunwe (isihloko sozwane). Ngemva kokuzalwa, ukuklebhula nokumunca kunethuba elihle lokusinda. Ingane ivuthiwe emavikini angu-40, inobude obungu-50cm kanye nesisindo esingaba ngu-3000 ~ 3300g. Isikhumba sipinki, amafutha angaphansi kwesikhumba akhule kahle, iningi lengane selinciphile, kanti izinwele zingu-2 ~ 3cm ubude. Uzipho lomunwe ludlule phezu kwesihloko somunwe. Ukunyakaza kwemilenze okusebenzayo, ukuklebhula okukhulu, i-reflex yokumunca enamandla. Ubude bomzimba wengane kanye nesisindo kuyanda kancane kancane ngenyanga yokukhulelwa, ukuze kube lula ukukhumbula, le fomula elandelayo ivame ukusetshenziswa ukubala: ngaphambi kwamasonto angama-20 ubude bokukhulelwa = isikwele senani lezinyanga zokukhulelwa (cm), ngemva kwamasonto angama-20 ubude bokukhulelwa = inani lezinyanga zokukhulelwa ×5 (cm).
Lo modeli ufanelekela amakolishi nasemanyuvesi ezokwelapha, kanye namanye amanyuvesi ezokwelapha, futhi udlala indima enkulu ekufundweni kwabahlengikazi bezokwelapha kanye nezifo zabesifazane.
