WebSeminiferous tubules are highly convoluted loops that range from about 120 to 300 µm in diameter and from 30 to 70 cm in length. They are arranged in lobules bounded by fibrous connective tissue. Each testis has hundreds of such tubules that are connected at both ends to the rete testis ( Figure 12.2 ). WebScattered throughout the loose connective tissue surrounding the seminiferous tubules are many highly specialized cells, the interstitial cells of Leydig, that produce testosterone. There are hundreds of individual seminiferous tubules in the body of the testicle which unite with one another to form a few dozen tubules that exit from the testicle and pass …

Sperm production, otherwise known as spermatogenesis, occurs in the male testes in structures called the seminiferous tubules. Overall, spermatogenesis aims to convert diploid primary germ cells into haploid mature sperm cells, which are able to fertilize a female’s egg cell.
Web5 jul. 2024 · Spermatocytogenesis is the first stage of Spermatogenesis that involves dividing single diploid (double) cells into four haploids (single) spermatocytes.
