A new type of alloplastic spermatocele: the bridge spermatocele
Microsurgery
|January 1, 1984
Abstract:
A new type of artificial spermatocele is proposed. A Gore-tex cylinder is sutured to the tails of the epididymides making a bridge between the two testes. The advantages of this spermatocele are (1) use of a single puncture; (2) easy execution of the puncture because the bridge stabilizes and holds the testicles in place; (3) a greater quantity of aspirate and, therefore, easier conservation of sperm; (4) a better quality of aspirate; and (5) relative ease of the surgical procedure.

01:41Spermatogenesis
Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male reproductive...
01:22Spermatogenesis
Spermatogenesis is a complex process that involves the development of sperm cells from undifferentiated stem cells in the seminiferous tubules of the testes. The process is essential for the production of mature and functional sperm cells that are capable of fertilizing an egg.
The process of spermatogenesis can be divided into mitosis, meiosis, and spermiogenesis. During mitosis, the spermatogonia or stem cells divide to produce two identical daughter cells, type A and B spermatogonia. Type-A...

01:15Sperm Transport
The journey of sperm from its origin to the point of ejaculation begins within the seminiferous tubules of the testis. Here, Sertoli cells produce fluid that propels non-motile sperm through a series of conduits, starting with the straight tubules leading to the rete testis. This interconnected network of tubules acts as the initial pathway for sperm, guiding them into the efferent ductules and then into the epididymis for maturation.
