A varicocele can affect testicular function, s***m production, and sometimes cause discomfort. Microsurgical varicocelectomy is a precise surgical technique used to treat varicocele while preserving important structures such as the testicular artery and lymphatics.

Good news from our clinic today! 🎉

We received a message from a couple we cared for — congratulations po! 🫶

This patient underwent a microsurgical subinguinal varicocelectomy for male factor infertility. 🔬😷

Varicocele is one of the most common treatable causes of male infertility, and in carefully selected patients — those with a palpable varicocele, abnormal semen parameters, and an infertile partner — surgical repair has real, evidence-based benefits: microsurgical subinguinal/inguinal repair offers the highest pregnancy rates and lowest recurrence and complication rates among surgical approaches.

Outcomes vary case to case, but with the right patient selection, this surgery can make a real difference for couples hoping to grow their family.

This is why we do what we do. 💙

Yesterday, I had the privilege to talk with fellow physicians about the potential benefits of antioxidant therapy in male infertility.

Male factor contributes to roughly half of cases, yet the man is frequently the last to be assessed — and by then, opportunities have been missed.

Antioxidants reliably improve semen parameters and DNA integrity, and probably improve pregnancy rates in carefully selected patients.

Ito ang holmium laser lithotripsy — tinatanggal ang bato mula sa loob.

May manipis na camera na dinaraan sa normal na daanan ng ihi. Walang operasyon sa tiyan o likod. Pag nakita na ang bato, may laser fiber — mas manipis pa sa spaghetti — na dinudurog ito parang buhangin.

Bakit ito ang pinipili namin:

✅ Walang sugat sa labas

✅ Madalas makakauwi agad sa loob ng 24 oras pagkatapos maoperahan

✅ Kayang durugin kahit matitigas na bato

✅ Mas mabilis ang balik-trabaho

Sumasakit ba ang bewang pabalik-balik? May dugo sa ihi? Mahapdi umihi? ’Wag ipagwalang-bahala — pwedeng masira ang kidney nang hindi mo namamalayan.

Ligtas na ang stone surgery ngayon. Magpatingin na.

🎙️ Honored and grateful to have been given the opportunity by the Department of Obstetrics and Gynecology of Asian Hospital and Medical Center to speak at Lumina 2026: The 9th Clinical Innovation Summit and Wellness Expo — held last May 29–31, 2026 at The Filinvest Tent, Alabang.

It was a privilege to bring the conversation on Erectile Dysfunction to both fellow clinicians and the general public — because men’s health is everyone’s business, and no one should face it alone. 💙

Maraming salamat sa inyong tiwala. Here’s to more open, evidence-based, and meaningful conversations about health! 🙏

Another day, another stone—precisely shattered.

Holmium laser lithotripsy lets us break ureteral stones into fine fragments with accuracy, minimal trauma, and faster recovery—no large incisions, just effective, targeted treatment.

Back to work. 💥
