The surge of interest in glucagon-like peptide 1 receptor agonists (GLP-1 RAs), such as semaglutide and tirzepatide, has actually raised concerns about what restorative results this class of medication may have beyond their present indicators for type 2 diabetes and weight problems.
Current medical trials have actually just recently determined take advantage of GLP-1 representatives for the heart, liver, and kidneys, however the existing proof base is murkier relating to how the drugs might impact male fertility.
Specialists state the connection in between GLP-1 RAs and enhanced male fertility makes good sense biologically. For beginners, obese and weight problems are highly related to male infertility in a number of overlapping methods. Weight problems can interrupt hormonal agents connected to fertility, increase the threat for faulty sperm, negatively impact semen quality, and even make sexual relations harder due to weight problems's link to impotence. As an outcome, GLP-1 RAs need to a minimum of in theory increase male fertility in males who take the drugs to reduce weight.
Animal research studies and a handful of little trials and observational information point to the capacity for GLP-1 RAs to enhance male fertility in other methods.
A current story evaluation on GLP-1 RAs and male reproductive health, released in the journal Medicina in December 2023, surveyed the capacity of the drugs for male infertility and provided factor for optimism.

Hossein Sadeghi-Nejad, MD, director of males's health at the NYU Grossman School of Medicine and a co-author of the post, stated that a person factor he and his associates performed their analysis was the recognized association in between weight reduction and a boost in testosterone.
“Most of the animal research studies that are out there reveal that this class of drugs does impact testosterone levels,” Sadeghi-Nejad stated; they wished to much better comprehend what other proof revealed about GLP-1 agonists and other fertility elements.
Connect Between Obesity and Fertility
The current paper initially evaluates the reputable link in between weight problems and poorer fertility results.

“Certainly, weight problems presents a considerable social issue with significant influence on both total health and financial elements,” senior author Ranjith Ramasamy, MD, an associate teacher of urology and director of the Reproductive Urology Fellowship program at the University of Miami's Miller School of Medicine, informed Medscape Medical News“The intensifying worldwide weight problems rates raise issues, particularly in the field of male infertility, where extreme body fat causes intrinsic hormone modifications causing changes, ultimately, in semen criteria.”
The authors kept in mind that weight problems has actually been connected in the research study to even worse assisted reproductive innovation (ART) results and to subfecundity, taking more than 12 months to accomplish pregnancy. They likewise referenced an organized evaluation that discovered guys with weight problems were most likely to have lower sperm counts and less feasible sperm.
“From our viewpoint, I believe the bottom line was to raise awareness about the truth that weight problems, due to the fact that of the aromatization of testosterone to estradiol [from excess adipose tissue]
