Study Notes
Puberty in Boys
- Puberty begins, usually between the ages of 11 and 15, but it isn't until then that all the parts of the reproductive system are in place
- The pituitary gland produces hormones that stimulate testes
- Production of testosterone brings about physical changes
- Timing and the stages of puberty vary for each individual
Sperm Development
- A male who has reached puberty will produce millions of sperm every day
- Sperm develops in tiny tubes within the testicles
- At birth, these tubes contain simple round cells
- Cells divide and change until they have a head and a tail
- Sperm move into the epididymis
- They mature there
Ejaculation
- Semen is a whitish fluid containing sperm
- The penis gets stiff and erect(an erection)
- When the penis is stimulated, muscles around the reproductive tract contract and force the semen through the duct system to the urethra
- Each time a guy ejaculates, it can contain up to 500 million sperm
Conception
- Millions of sperm “swim” up from the vagina through the fallopian tube
- If the sperm meets the egg, the egg is fertilized
- The fertilized egg is called a zygote which contains 46 chromosomes
- The zygote divides again and again
- Ultimately, it forms an embryo, then a fetus and finally a newborn baby
