Sertoli cells Sertoli cells Sertoli cells yog cov hlwb somatic ntawm testis uas yog qhov tseem ceeb rau kev tsim cov qe ntshav thiab spermatogenesis. Sertoli hlwb pab txhawb txoj kev loj hlob ntawm cov kab mob mus rau spermatozoa los ntawm kev sib cuag ncaj qha thiab los ntawm kev tswj hwm ib puag ncig milieu hauv cov tubules seminiferous. https://pubmed.ncbi.nlm.nih.gov › …

muaj receptors rau follicle stimulating hormone (FSH) thiab testosteroneuas yog cov tshuaj hormonal tseem ceeb ntawm spermatogenesis.
Cov tshuaj hormones twg tswj cov txheej txheem spermatogenesis thiab tsim cov phev?
Testosterone yog cov androgen loj hauv lub testis uas tswj cov spermatogenesis. Testosterone yog tsim los ntawm Leydig cell nyob rau hauv teb rau stimulation nrog luteinizing hormone (LH) thiab ua raws li ib tug paracrine yam uas diffuses mus rau hauv lub seminiferous tubules.
Lub luag haujlwm ntawm cov tshuaj hormones hauv spermatogenesis yog dab tsi?
LH txhawb nqa Leydig cell T ntau lawm, thiab FSH txhawb nqa hauv Sertoli hlwb, hauv kev sib koom ua ke nrog T, kev tsim cov tshuaj tswj cov molecules thiab cov as-ham uas xav tau rau kev saib xyuas cov spermatogenesis. Li no, ob qho tib si T thiab FSH tswj cov spermatogenesis ncaj qha los ntawm Sertoli hlwb.
