Introduction

Glycemic control directly influences quality of life — including sexual life. Many patients do not make the connection between glycemic values and sexual function, yet this connection is essential.

What does uncontrolled blood glucose mean?

frequently elevated blood glucose levels
HbA1c above target
large fluctuations in blood glucose

Effects on sexual function

1. Erectile dysfunction

vascular impairment
neuropathy

2. Decreased sexual desire

reduced testosterone
fatigue

3. Impaired sexual performance

unstable erections
difficulties maintaining erections

4. Psychological impact

performance anxiety
sexual avoidance
decreased self-esteem

Vicious cycle

erectile dysfunction → stress → poorer glycemic control → worsening of erectile dysfunction

Can it be improved?

YES.

Through:

optimal glycemic control
healthy lifestyle
appropriate treatment

sexual function can be significantly improved.

Conclusion

Sexual life reflects metabolic status.
Well-controlled diabetes also means a better sexual life.

A single injection for cholesterol — from dreams to first human results

A Phase 1 trial published in the New England Journal of Medicine (November 2025) brings remarkable results: a single infusion of CTX310, a CRISPR-Cas9 therapy developed by Cleveland Clinic and CRISPR Therapeutics, reduced LDL cholesterol by up to 49% and triglycerides by up to 55% in patients with refractory dyslipidemia — without serious adverse events. The mechanism is unique: instead of blocking a protein or interfering with its mRNA, CTX310 permanently edits the ANGPTL3 gene in hepatic cells, mimicking a natural mutation associated with reduced cardiovascular risk throughout life. The therapy is currently in Phase 1b clinical stage, with updates expected in the second half of 2026. It is not approved and does not replace current treatments.
