One particular hormone which shows up in males at a constant amount throughout their lives, may function as the root cause of a number of age related health problems, including bone weakness, cancer, diabetes, sexual dysfunction, along with cardiovascular disease.
This particular hormone is known as INSL3 and it enters the body initially during puberty. Its levels just somewhat decrease from that time onwards in the age of 70. This consistency, and also the early age at which it appears, makes INSL3 important to researchers and perhaps to male’s health.
An individual that has decreased levels of INSL3 at a young age is likely to have lower levels of the hormone later on, “she said. In case that means a greater chance of health problems, as the research indicates, then those health consequences might be managed several years earlier.
“Understanding the reason some individuals tend to be more apt to have disease and disability as they grow older is essential so that solutions can be discovered to guarantee a healthy and long life,” Ravinder Anand Ivell, a reproductive endocrinologist at the University of Nottingham, UK.
“the discovery of hormones is a crucial step in knowing this and can pave the way for assisting individuals but additionally supporting us to relieve the care crisis we have as a society,” she said.
INSL3 is created by the same cells in the testes that produce testosterone; unlike testosterone, INSL3 does not fluctuate as men become adults.
To monitor the amount of INSL3 in the blood, researchers had taken samples from over 2,200 men across 8 various local facilities in Europe. The men’s INSL3 levels stayed steady with time and also varied significantly between individuals, enough to tease apart health risks.
Researchers suggest that INSL3 levels in the blood reliably correlate to the number and overall health of the Leydig cells in the testes – having far fewer of these cells and also less testosterone has also been associated with many health issues in later life.
“Now we all know the key role this particular hormone plays in predicting illness and just how it varies amongst men, we’re turning the attention of ours to finding out what elements have the most impact on the level of INSL3 in the blood,” says molecular endocrinologist Richard Ivell from the University of Nottingham.

“Preliminary work suggests early life nutrition could play a role, but many other things such as genetics or exposure to several environmental endocrine disruptors could play a part.”
Across nine morbidity categories that participants reported in questionnaires, including cancer, diabetes, and cardiovascular disease, INSL3 was linked to an increased risk of morbidity in eight of them (only depression was not found to have any correlation in this study).
But when the researchers adjusted for other hormonal and lifestyle factors, like BMI and smoking status, most of those associations with INSL3 were lost, aside from hypertension and cardiovascular disease.
And testing whether INSL3 levels in blood samples from a subset of males could foreshadow health outcomes about four years further along, lower hormone levels were connected with seven of the 9 comorbidity categories. However, this was without considering additional factors.
One area the researchers are keen to examine in later studies is exactly how INSL3 relates to sexual well being, with its strong association with testosterone, but that wasn’t provided in detail in this particular piece of research.
Future studies must also “focus on greater time periods to determine whether INSL3 measured in younger or middle-aged men… is really predictive of the later appearance of age dependent health issue,” the scientists conclude.
If the link between INSL3 and these health risks is established by further studies, along with researchers are in a position to identify exactly why the link exists, it means preparations could be done much earlier in an attempt to spot – and stop – a variety of age-related health issues from happening.
“The holy grail of aging research is reducing the health gap which appears as people age,” says Anand Ivell.
The research has been published in Frontiers in Endocrinology.
