Male infertility: An updated work-up

2:00-11:57

Here's a summary of the key points from the YouTube video transcript in 10 bullet points:

1. The video discusses male infertility diagnostics, treatments, and its connection to overall men's health.

2. Basic diagnostic workup includes clinical history, physical exam, semen analysis, hormone evaluation, and in some cases genetic testing and imaging.

3. New diagnostic tools like next-generation sequencing are helping identify genetic causes of male infertility.

4. Hormonal treatments, including gonadotropins, can be effective for certain types of male infertility, especially secondary hypogonadism.

5. Lifestyle modifications like weight loss and stopping smoking are recommended for infertile men.

6. Varicocele treatment, especially microsurgical approaches, can improve natural conception rates in selected patients.

7. Sperm DNA fragmentation testing may be useful in some cases, though more research is needed.

8. For obstructive azoospermia, surgical techniques like vasovasostomy can be effective but outcomes depend on factors like time since vasectomy.

9. Male infertility is increasingly seen as a potential indicator of overall health issues, with infertile men having higher rates of comorbidities.

10. Long-term follow-up shows infertile men are at higher risk of developing health conditions like cardiovascular disorders and cancer over time.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
