Study Notes
Pathway of Sperm
- Sperm production follows the SEVEn UP pathway:
- Seminiferous tubules: Site of sperm production
- Epididymis: Location for sperm maturation and storage
- Vas deferens: Tube transporting sperm to urethra
- Ejaculatory duct: Connects the vas deferens to the urethra
- Urethra: Conducts sperm to exterior
- Penis: Final exit point for sperm
Epididymis
- Responsible for sperm maturation and storage, providing the necessary conditions for sperm to develop fully before ejaculation.
Vas Deferens
- A muscular tube that transports sperm from the epididymis to the urethra, playing a critical role in the male reproductive system.
Prostate Gland
- Contributes to seminal fluid, nourishing and protecting sperm; plays a significant role in fertility.
Erectile Tissue
- Corpora Cavernosa: Paired erectile tissues that fill with blood during arousal, contributing to penis erection.
- Corpus Spongiosum: Surrounds the urethra and keeps it open for ejaculation, also engorges with blood but to a lesser degree than corpora cavernosa.
Glans Penis
- The head of the penis, highly sensitive and important for sexual pleasure.
Frenulum
- Indentation located on the underside of the penis; known as the most sensitive area and classified as an erogenous zone.
Sperm Production
- Occurs in the seminiferous tubules, where spermatagonia develop into sperm cells.
Cells in Seminiferous Tubules
- Spermatagonia: Stem cells that give rise to sperm cells.
- Sertoli Cells: Provide support and nourishment to developing sperm cells.
Cells Between Tubules
- Leydig Cells: Located between seminiferous tubules, these produce hormones, primarily testosterone, essential for male reproductive development.
