Puberty begins later with boys from the age of 10 to 17 The first sign of puberty in boys is an increase in size of the testicles. This is followed a few months later by the growth of pubic hair. Puberty continues with an increase in size of the testicles and penis and continued growth of pubic and axillary hair. Boys undergo their peak growth spurt about 2-3 years later than girls. Also, this usually begins with an enlargement of the hands and feet and is later followed by growth in the arms, legs, trunk and chest. Other changes include a deepening of the voice, an increase in muscle mass, the ability to get erections and ejaculate (especially spontaneous nocturnal emissions or 'wet dreams'), and in some boys, breast development (gynecomastia). Development continues and the whole process is completed in 3-4 years, eventually reaching adult testicle and penis size and an adult pattern of pubic hair. This is followed by the development of chest and facial hair.

Puberty is also associated with adolescents beginning to have axillary perspiration and body odor, and acne.

(2-part post):

As Honky-tonk's answer (which seems to have been 'copied and pasted' directly from somewhere like Wikipedia) states, the age at which puberty starts can vary greatly.

While that answer is accurate, it might not be particularly helpful to you, so I'll approach it from the experiences of many years teaching in a secondary school;

Year 7 (11 and 12 year olds): 'Once in a blue moon', there might be a boy whose physical appearance, dropped voice or personality traits suggest that he's started puberty prior to entering Year 7 but this is extremely rare. It was also very rare to detect any significant signs of puberty in any boy throughout this year.

Year 8 (12 and 13 year olds): At the start of the year, most boys would have the characteristics associated with a pre-pubescent child. By the end of the year, about half of all boys would be starting to show some physical signs of puberty. (e.g. 'fluff' growing on their upper lips or the first signs of acne).

Year 9 (13 and 14 year olds): This is the year when teachers really notice changes in many boys. Quiet shy boys can suddenly blossom into confident individuals while formerly pleasant children seem to transmogrify into ogres. There's often a noticeable growth spurt during the year, many voices drop, acne becomes common and thin moustaches become more noticeable. By the end of the year, only a very small minority of boys (10%?) will look like children; most will be starting to look like young men.

Year 10 (14 and 15 year olds): During this year, most boys complete much of the physical transformation into young men. By the end of the year, it's as rare to spot a completely pre-pubescent boy as it is to find a fully pubescent boy in Year 7.

None of that information conflicts with previous posts but I hope that it makes the situation clearer. It should be noted that most people refer to 'going through puberty' as a process which lasts a year or so. From a medical standpoint, this isn't strictly accurate as many of the changes which commence in the early teen years aren't fully complete until after the age of 20. (It's just that the most dramatic changes happen early on).

The Jewish faith recognises adulthood as starting with a boy's barmitzvah at the age of 13. This is for sound biological reasons and, if asked to define a specific age at which puberty starts (for boys), many people would opt for 13 as a rough figure.
