If you see this card
Patingin nung picture about flow of seminal fluid plssss
Familiarize the detailed flow of sperm production to ejaculation
- Sperm develop as tiney round cells in seminiforous tubules of testicles
- Hormones from testicles and pituitary gland help sperm mature
- They travel to epididymis and develop further for several weeks
- Migration to vas deferens
- Travel to seminal gland, nourished by semen fluid
- Travel to prostate gland and mix with prostate fluids
- Exit through urethra during ejaculation

IMPORTANCE OF SEMEN ANALYSIS
