Study Notes
Male Reproductive System Overview
- Cremaster muscle regulates testicular temperature, vital for sperm viability, by contracting or relaxing to maintain a cooler environment than the body temperature.
Sperm Motility Enhancers
- Seminal vesicles produce alkaline fluid, aiding sperm motility and survival in the acidic vaginal environment.
- Prostate gland secretes seminal fluid significantly enhancing sperm motility during ejaculation.
- Bulbourethral glands contribute additional fluid to semen, improving sperm motility.
Protecting Sperm During Intercourse
- Prostate gland plays a crucial role by secreting seminal fluid that protects sperm from vaginal acidity, ensuring sperm survival during intercourse.
Changes During Male Sexual Maturation
- Testosterone influences adrenal glands, promoting development of secondary sexual characteristics like deeper voice and increased muscle mass.
- Luteinizing hormone (LH) stimulates the testes to produce testosterone, leading to further sexual maturation.
Role of the Hypothalamus
- Hypothalamus releases gonadotropin-releasing hormone (GnRH), initiating puberty and stimulating male sexual maturation, including testicular enlargement.
Functions of Testosterone
- Testosterone contributes to the growth of the skeletal system, enhancing bone density and overall growth during male maturation.
