III. Semen

• A. Composition

  • Only 1-5% is actually sperm.

  • Average speed of 28 mph.
  • Speed slows down immediately after ejaculation.
  • Sperm take 30 minutes to 24 hours to reach the egg.
  • Only one sperm fertilizes the egg.  

IV. Other Male Issues

• A. Baldness

  • Male-pattern baldness: Caused by genes affecting 30-50% of men.  
  • Sensitivity to dihydrotestosterone (DHT), causing hair follicles to shrink.  

• B. Hair Loss Treatment

  • Minoxidil (Rogaine): Topical treatment promoting hair growth.  
  • Finasteride: Pill suppressing DHT production.  
  • Platelet-Rich Plasma (PRP) injections: Stimulate hair growth.

V. Puberty

• A. Onset

  • Varies between individuals, starting as early as 8 or as late as 14.
  • Average age of onset has decreased over time.

• B. Causes of Early Onset

  • Exposure to synthetic chemicals interfering with hormone regulation.  
  • Higher stress levels in developing cities or fast-paced societies.
  • Childhood obesity.

• C. Voice Change

  • Testosterone signals voice box to change, resulting in a lower and deeper voice.
  • Cartilage in the voice box grows, vocal cords become larger, and larynx moves down.  
  • Voice cracking occurs due to the brain adjusting to the changes.

VI. Penis Size

• A. Average Size

  • Erect: 5.1-5.5 inches (13-14 cm)
  • Flaccid: 3.61 inches (9.2 cm)
  • Men tend to overestimate average size.

• B. Increase in Average Size

  • Earlier onset of puberty.
  • Larger body sizes due to better access to food and hormone-altering substances.

• C. Does Size Matter?

  • No, for function or desirability.
  • Women prefer average to slightly above-average sizes.

• D. Penis Enlargement Methods

  • Penis pumps: Temporary increase using suction.  
  • Jelqing: Stretching exercises with no scientific evidence.  
  • Surgical implantation: Permanent increase with high cost and painful recovery.

VII. Other Penis-Related Facts

• A. Foot Size and Penis Size

  • No correlation between the two.

• B. Peyronie's Disease

  • Scar tissue develops on the penis, causing curvature and pain.  
  • Can lead to difficulty having sex and penis shortening.
  • Treatments: Traction therapy, medication, or surgery.

• C. Erectile Dysfunction (ED)

  • Affects 18-30 million men in the US and 40% of men globally by age 40.
  • Possible causes: Chronic gum disease, heart disease, high blood pressure, high blood sugar, or diabetes.
  • Consult a doctor if experiencing ED.

• D. Foreskin

  • Double layer of skin and mucus membrane covering the penis head.
  • Possible functions: Protection from dust, particulates, and bug bites.
  • Uncircumcised men have a higher risk of contracting HIV.  
  • Circumcision reduces HIV risk by 60%.  

• E. Testes Location

  • Outside the body to maintain a cooler temperature for sperm production.
  • Cremaster muscles pull testicles closer to the groin for warmth.  

• F. Boxers or Briefs

  • Briefs may slightly increase testicular temperature but have no significant impact on sperm production.
  • Briefs offer better support, while boxers provide better airflow.
  • Choice depends on individual preference.

• Nitric oxide, similar to nitrous oxide used as an anesthetic, relaxes muscles in the groin and increases blood flow to cause erections.  
• Wet dreams may be a coping mechanism for stress.
• Serotonin imbalance may contribute to premature ejaculation.  
• The average ejaculation speed is 28 mph, faster than the speed limit in many residential neighborhoods.
• 15,000 hair follicles on the male face alone.

PART 4: Conclusion in Essay Form

This extensive exploration of the male body has unveiled a multitude of fascinating and sometimes surprising facts. From the hormonal fluctuations that cause unexpected erections and morning wood to the complex composition of semen and the factors influencing penis size, we've delved into the intricacies of male physiology. We've also addressed common concerns like baldness, premature ejaculation, and erectile dysfunction, highlighting potential causes and treatment options. Additionally, we've explored the evolutionary and cultural aspects of male anatomy, such as the purpose of the foreskin and the reasons behind testes location.

One key takeaway is the importance of understanding and accepting the natural variations in male bodies. Whether it's the age of puberty onset, penis size, or susceptibility to baldness, every individual is unique. While concerns about these aspects are natural, it's crucial to remember that they don't define a man's worth or masculinity. Open communication with healthcare professionals and partners is essential for addressing any concerns and maintaining overall health and well-being.

Ultimately, this journey through the male body serves as a reminder of the complexity and resilience of the human form. By gaining a deeper understanding of our bodies, we can foster greater self-acceptance, make informed decisions about our health, and appreciate the remarkable processes that keep us functioning every day.
