Siv cov qauv nas uas tsis muaj lub xov tooj ntawm tes cilia hauv lawv cov oviducts - qhov sib npaug ntawm cov hlab ntsha hauv cov poj niam - cov kws tshawb fawb tau coj mus rau qhov pom. kev txiav txim lub luag hauj lwm ntawm cov cilia nyob rau hauv fertilization.
Hauv lawv txoj kev tshawb fawb, luam tawm thaum lub Tsib Hlis 24, 2021 hauv phau ntawv journal "PNAS”, Cov kws tshawb fawb los ntawm lub koom haum Lundquist (California, United States) tau qhia tias mobile plaub muag tam sim no nyob rau hauv Cov hlab ntsha hauv lub cev, txuas lub zes qe menyuam mus rau lub tsev menyuam, yog qhov tseem ceeb rau lub rooj sib tham ntawm gametes. - phev thiab ovum. Vim tias qhov kev cuam tshuam me ntsis ntawm cov qauv ntawm cov cilia los yog lawv qhov kev ntaus ntawm lub raj funnel (ib feem hu ua infundibulum) ua rau ovulation tsis ua hauj lwm, thiab yog li ntawd rau poj niam infertility. Qhov no yog ib qho tseem ceeb nrhiav tau, txij li qhov teeb meem ntawm kev thauj cov qe mus rau hauv lub uterine kab noj hniav yog paub tias yuav ua rau muaj kev pheej hmoo ntawm cev xeeb tub ectopic.
Nyob rau hauv ib nqe lus, cov kws sau ntawv ntawm txoj kev tshawb no nco qab tias thaum lub qe yog fertilized los ntawm ib tug phev nyob rau hauv nruab nrab ntawm lub fallopian raj, lub qe-cell tsim yuav tsum tau thauj mus rau lub tsev me nyuam kab noj hniav rau lub embryonic implantation (los yog nidation).
