What is Testicle (Testis)? The testicles, also known as testes (plural of testis), are the primary male reproductive organs, responsible for producing both sperm and hormones, primarily testosterone. These organs are homologous to the ovaries in females and serve critical roles in both the endocrine and exocrine systems. Testosterone, an essential androgen for male development and reproductive function, is regulated by the luteinizing hormone (LH) from the anterior pituitary gland. Meanwhile ... The testes (singular: testis) are paired male gonads responsible for the production of spermatozoa and the secretion of androgens, primarily testosterone. Enclosed in a fibrous capsule and suspended in the scrotum by the spermatic cords, the testes are vital for male fertility and secondary sexual characteristics. They develop intra-abdominally and descend into the scrotum during fetal life. Each testis is surrounded by multiple layers derived from the anterior abdominal wall, and its ... A testicle or testis is the gonad in males that produces sperm and testosterone. Learn about its structure, development, blood supply, and disorders from this comprehensive article. The testes are the paired male gonads that produce sperm and the male sex hormones, primarily testosterone. It is covered by a thick covering of fibrous tissue, the ‘tunica albuginea (Figure 19). The epididymis is attached to its posterolateral surface, whereas the vas deferens arises from the lower pole of the epididymis and runs up medial to it, behind the testis. The front and sides of the testis lie free in a closed peritoneal sac, the ‘tunica vaginalis,’ and a remnant of the fetal ...
