Compared to other primates, the human penis is larger and thicker overall in relation to body mass.For the first six weeks or so after conception, human embryos develop as default female children, mostly using the mother's DNA for genetic information. Around the sixth week of development, if the embryo is male, the Y chromosome's SRY gene will begin to produce androgens like testosterone. These androgens inhibit the further development of feminine traits while fostering the development of masculine traits.

A collection of ten short facts about man :

1. When it came to Old English, "man" meant all of humanity, whereas "wer" meant particular male humans. Throughout the thirteenth century, man gradually surpassed the term wer, which denoted an adult male human, but wer continued to apply to the entire human species.
2. Boys are 25% more likely than girls to die in infancy worldwide.
3. In the United States, men are typically little over 5' 9" (175 cm) tall and weigh about 190 pounds (86 kg). Men were typically around 5' 8" (172 cm) tall and just over 166 pounds (75 kg) heavy in 1960.
4. Globally, women expect to live an average of 68.76 years, while males expect to live an average of 64.52 years.
5. Men in the United States die primarily from heart disease, much like women do, and the average age of a first heart attack is only 66 years old.
6. Men misuse alcohol almost three times more frequently than women do, and they abuse recreational drugs like cocaine and marijuana twice as frequently.
7. Men in the US die more than five years younger than women, and they have higher death rates from all 15 major causes of death (apart from Alzheimer's disease)..
8. Adult male brains are roughly 10% bigger overall than adult female brains. Men typically need more neurons in their brains to govern their bodies than women do because of their larger stature and greater muscle mass.
9. The term "boy" has been used to describe a male child since 1154 A.D. Although the name's precise etymology is uncertain, it is said to have originated from the Anglo-Saxon word boia, which meant "farm worker" or "servant."
10. Boys typically experience growth spurts, a shift in voice tone, and the onset of secondary sex features between the ages of 12 and 14 when they go through puberty. In the same age range, boys often approach puberty later than girls.
