Forum Name: Male Sexual Disorders

Question: Slow sexual development and obesity.

 jigg2020 - Thu Feb 08, 2007 4:26 pm

I'm an 18 year old male(19 in 3 months).I've been overwieght since i was 10-11 years old and extremely obese for the last 3-4 years.My weight one year ago was about 130 kgs.Now i've reduced to about 96 kgs,mainly through dieting over the last 9 months.I also had gynocomasta(with brest tissue) for which i underwent surgery.My height is 6'1.
My puberty started when i was 13-14.I started having pubic hair when i was 14.But no external changes like voice cracking or moustache.Since then my dvelopment has progeressed very slowly with my voice cracking and little facial hair appearing at 17.Now at 18 i still look like a 13-14 year old.My skin is still soft and smoothThough i have some hair in my arms and legs.My pubic hair has also developed completly and i also have hair in my armpits.My penis size has also not incerased.I think my libido is quiet norrmal.

I've had my hormones tested:
Before i had a brief course of hcg as precribed my doctor for 3 months:
fsh:3.1 mIU/ml
LH:4.6 m IU/ml
Prolactin:6.6 ng/ml
Testotorne:3.3 ng/ml
After treatment:
Testestorone:3.2 ng/ml

Test results taken recently from another lab:
Serum testostorone: 5.28 ng/ml
Serum free testostorone:13.5 pg/ml
FSH:5.6 mIU/ml
LH:6.10 mIU/ml
prolactin 6.10 mIU/ml
Estradiol:45.75 pg/ml

Is the reason for my condition my past obesity?and is there any treatment for my condition other than it eventualy taking care of itself by reduction of my wieght?

User avatar Your labs and developmental description are indicative of testosterone deficiency. It is possible that obesity is contributing some to this as fat tissue converts testosterone into estrogen (loosely speaking); however, your estrogen levels are not elevated. This makes me think you may have a primary testosterone deficiency rather than a secondary issue.

It is interesting that your LH and FSH are normal. This would seem to indicate that your pituitary gland is not recognizing that your testosterone levels are low.

I would suggest that you discuss this with an endocrinologist. You should probably have your growth hormone tested as well. The obesity may have masked a deficiency in growth. (I don't know for sure if this can occur but obesity does lead to accelerated growth in those with normal growth hormone so I suspect it would do the same in growth hormone deficiency.) Growth hormone deficiency is associated with reduce penis growth.

Pubic and axillary hair is not driven by testosterone. This is likely the reason that you have had normal development of these without the associated other puberty changes.

Hope this helps. Keep us updated.

User avatar Sorry, I forgot to mention that treatments are available for both testosterone deficiency and growth hormone deficiency. At your age, if you do have a deficiency, replacement should still yield good effects.
