The male testes have tiny tubules containing diploid cells called spermatogonium that mature to become sperm. The basic function of spermatogenesis is to turn each one of the diploid spermatogonium into four haploid sperm cells. This quadrupling is accomplished through the meiotic cell division detailed in the last section. During interphase before meiosis I, the spermatogonium's 46 single chromosomes are replicated to form 46 pairs of sister chromatids, which then exchange genetic material through synapsis before the first meiotic division. In meiosis II, the two daughter cells go through a second division to yield four cells containing a unique set of 23 single chromosomes that ultimately mature into four sperm cells. Starting at puberty, a male will produce literally millions of sperm every single day for the rest of his life.
What else can I help you with?
Which cells types support and nourishes the cells of the spermatogenic lineage?
Sertoli cells within the seminiferous tubules of the testes provide physical and nutritional support to the developing germ cells of the spermatogenic lineage. They regulate the microenvironment within the tubules, provide structural support, and also secrete various factors necessary for sperm production.
What type of cell is the least mature type of spermatogenic cell?
The least mature type of spermatogenic cell is the spermatogonium. Spermatogonia are the stem cells located in the seminiferous tubules of the testes, responsible for undergoing mitosis to produce more spermatogonia or differentiate into primary spermatocytes. They represent the earliest stage in the process of spermatogenesis, which ultimately leads to the formation of mature sperm cells.
Are sperm cells formed within the female flower plarts?
Sperm cells are not formed in the female flower parts, called the Oogonia. The sperms cells are formed within the male flower reproductive organs, called Antheridia. These sperm cells form from spermatogenic tissue.
What cells of the epithelium line the seminiferous tubule give rise to sperm cell?
Spermatogonia, which are stem cells located within the seminiferous tubules of the testes, give rise to sperm cells. These spermatogonia undergo repeated rounds of cell division through the process of spermatogenesis to produce mature spermatozoa.

What produced sperm cell?
Cells do not produce sperm. Spermatozoa, also known as sperm cells, are produced in the testes.
Which cells types support and nourishes the cells of the spermatogenic lineage?
Sertoli cells within the seminiferous tubules of the testes provide physical and nutritional support to the developing germ cells of the spermatogenic lineage. They regulate the microenvironment within the tubules, provide structural support, and also secrete various factors necessary for sperm production.
What hormone keeps the concentration of testosterone in the vicinity of the spermatogenic cells high to stimulate spermatogenesis?
Androgen-binding protein (ABP)
What are the spermatogenic cells?
Spermatogenic cells are the cells within the testes that undergo spermatogenesis, the process of sperm production. These cells include spermatogonia (stem cells), primary and secondary spermatocytes, spermatids, and spermatozoa. They go through a series of mitotic and meiotic divisions to develop into mature sperm cells.
What type of cell is the least mature type of spermatogenic cell?
The least mature type of spermatogenic cell is the spermatogonium. Spermatogonia are the stem cells located in the seminiferous tubules of the testes, responsible for undergoing mitosis to produce more spermatogonia or differentiate into primary spermatocytes.
