Usually, these changes begin between the ages of 8 and 14 for girls, and between 9 and 15 for guys. This wide range in age is normal, and it's why you may develop several years earlier (or later) than most of your friends.
The average age for girls to start puberty is 11, while for boys the average age is 12. But it's perfectly normal for puberty to begin at any point between the ages of 8 and 13 in girls and 9 and 14 in boys.

Erections are a perfectly normal function of the male body, especially in guys who are going through puberty.
In most cases, delayed puberty is nothing to worry about. Every kid is different and some just start sexual development later than others. But in some cases, there is a medical cause for the delay that requires treatment.
Conclusions: Final height is influenced by both height and the age of onset of the PGS in normal maturing children. A normal but early puberty exerts a negative effect on final height. A delayed PGS exerts a positive effect on final height.
You were likely a late bloomer if you started puberty later, hit your own growth spurt as an older teen, or didn't get your first period until you were older than 14. Your child's healthcare provider will ask about family history to figure out if your child may be a late bloomer.

Second puberty isn't a real medical term. People use it to describe how your body changes during your 20s, 30s, and 40s. The term can be misleading, as these changes are different from puberty during adolescence. Many age-related changes are due to declining hormone levels over time.

Testicles that do not drop by about one year of age should be examined by a surgeon. It is thought that by three years of age, if the testicles have not dropped, surgery should be done to prevent permanent damage to the testicles.
You produce sperm every day, but a full sperm regeneration cycle (spermatogenesis) takes about 64 days.
Spermarche—also known as semenarche—is the beginning of development of sperm in boys' testicles at puberty. It is the counterpart of menarche in girls. Depending on their upbringing, cultural differences, and prior sexual knowledge, boys may have different reactions to spermarche, ranging from fear to excitement.
Delayed puberty affects about 2% of adolescents. Most commonly, puberty may be delayed for several years and still occur normally, in which case it is considered constitutional delay of growth and puberty, a common variation of healthy physical development.
On average, boys reach puberty later than girls, and researchers have found that the differences in the onset of puberty could explain around half of the gender differences in grades. “Pupils who reach puberty earlier perform better. This applies to both boys and girls.
Delayed puberty in boys is when puberty does not begin by 14 years of age. When puberty is delayed, these changes either don't occur or don't progress normally.
