As spermatogenic cells mature, they migrate from the outer edge of the seminiferous tubule toward the lumen.

Spermatogenic Cells

Cells located in the testis that undergo meiosis to produce spermatocytes, which ultimately develop into mature spermatozoa.

Seminiferous Tubule

Narrow, coiled tubules within the testes where sperm are produced and mature.

Lumen

The interior space or cavity of a tubular structure, such as a blood vessel or intestine, through which liquids and substances move.
