There is no formal definition of “second puberty,” including when or why it happens because it is not a medical word. The term “second puberty” is slang for changes after adolescence. In addition, people may use the phrases differently when referring to particular eras, such as the change from the 20s to the 30s.


We’ll try to answer the questions of what causes second puberty and how to prepare for its inevitable arrival. 


Second Puberty: Male Symptoms


This may be what happens during the manly version of second puberty.


In His Twenties:


You are still going through a period of rapid physical development as you leave your teenage years behind. So, physical alterations such as:


  • Increased bone density (having the most bone tissue at this point in your life),
  • Prostate growth retardation, as the development proceeds at a snail’s pace after the age of twenty.
  • An increased amount of muscle mass.


In His Thirties:


Lowered testosterone levels are a common symptom of entering middle age. However, there will be no outward manifestations of this.

If you do age, you’ll probably suffer the typical bodily changes that come with it. Some of these things might be:


  • In your mid-to-late-30s, you begin to experience a gradual loss of bone mass.
  • The loss of previously acquired muscular mass. You start to lose muscle.
  • In your late 30s, wrinkles and age spots may start to appear.
  • Hair that’s starting to get grey. The average age at which people begin to see grey hair is around 35.


In His Forties:


In this phase, low testosterone levels will manifest themselves physically. This transition is known as andropause or male menopause.

Here are the prominent symptoms of this phase:


  • When testosterone levels drop, it is harder to keep an erection going strong, so impotence issues are a common complaint.
  • There is the displacement of body fat. The abdomen and chest are familiar places for fat to collect.
  • This phase features the development of a larger prostate. 
  • The discs that separate each of your spinal bones start to degenerate. One or two inches of your height might be lost.


Second Puberty: Female Symptoms


The physical manifestations of second puberty in females are varied. Here is everything that you can anticipate:


In Her Twenties:


Your body is still developing and maturing as a young lady. Around this period is when most people feel their physical best. Some of the observable alterations in body structure are:


  • The bone mass is at its highest in your twenties.
  • The muscles will be at their peak at this time, much like a man’s
  • Estrogen levels are highest in a woman’s mid to late twenties, which is why menstruation patterns stabilise around this time.


In Her Thirties:


Perimenopause, sometimes known as the “second puberty,” is the transitional period between reproductive years. It usually begins when a person is in their mid-to-late-30s, though it can begin earlier.

The physical symptoms of perimenopause are the result of fluctuating estrogen levels. The common symptoms are:


  • The quantity of bone in your body starts to diminish.
  • The loss of previously acquired muscular mass.
  •  Wrinkles and saggy skin can appear when your skin loses its elasticity and firmness.
  •  The hair may begin to grey in patches.
  •  The menstrual cycle will become irregular as women near their 40s, and fertility drops along with it.
  • A sensation of dryness in the genital area
  • Hot flashes.


In Her Forties:


Menopause will affect your body by the time you reach your late forties. It has been likened to a “second puberty” by some.


The highlighted symptoms of this stage are:


  • Accelerated bone resorption because when menopause hits, bone loss speeds up.
  • Women, like men, shrink in stature when the discs in their spines degenerate.
  • Women tend to put on more weight as the body metabolism slows down
  • Missed or irregular menstruation due to decreased estrogen levels


Second Puberty: What Happens in A Transgender’s Body?


In some instances, transgender people who choose to get gender-affirming therapy after their first adolescence may go through puberty again. Hormone therapy may trigger gender-congruent puberty in the person receiving it.


The total effect of hormone treatment on a person’s body might take anywhere from a month to five years to manifest. On average, cisgender persons need five years to go through puberty. However, hormone treatment, on the other hand, can lead to rapid emotional changes, alleviating gender dysphoria symptoms in a matter of weeks.


Hormone treatment for transwomen results in breast growth, softer skin, sparser body hair, fat storage in the hips, thighs, and butt, and emotional shifts. Moreover, changes in the voice, clitoris size, and the absence of periods are all to be expected.


Muscle growth and a general body reshaping are two of the most apparent changes trans men may expect to see in their bodies as they transition. Your skin will produce more oil, your facial hair will grow, and you may even lose some of your head hair.


Tips For Easing Into “Second Puberty”


To keep your health in check during your second puberty, consider the following tips:


  •  Maintaining an active lifestyle is crucial while dealing with the effects of ageing. Activities like swimming, Pilates, yoga, running, and dance might fit this category.
  • Get plenty of shut-eye by adhering to consistent bed-and-wake timings.
  • Fruits, vegetables, whole grains and starches, healthy fats, and lean meats are all essential components of a balanced diet. Eating well may aid in weight control, protect against diseases like osteoporosis, and boost mental and digestive well-being.
  • For keeping your skin healthy, acquire the help of emollients and retinoid creams prescribed by doctors.
  • As far as hair care is concerned, there are treatments available without a prescription that can potentially promote hair growth.
  • Discuss this with your doctor if you are unsure if multivitamins are necessary. Nutrient-poor bodies can get what they need from them.




Second puberty is a term used to describe these transitions that occur in the body during your twenties, thirties, forties, and beyond. Being prepared for the changes that come with age might make going through second puberty much more manageable.
