Alasdair Walker on DNA Fragmentation, Varicocele and Overcoming 7 Failed IVF Cycles

In this episode of The Male Fertility Podcast, biomedical engineer Alasdair Walker joins hosts Ciaran and Shaun to share his extraordinary transformation from seven failed IVF cycles to natural conception success. Based in Scotland with a doctorate in biomedical engineering, Alasdair's journey began when his wife Julia's ear infection unexpectedly triggered their fertility investigation.

Alasdair had every advantage a fertility patient could hope for. After six years together and a year of marriage, Alasdair received a devastating diagnosis: severe oligospermia with just 200,000 sperm per ml. Born with only one testicle after losing the right one at five weeks old, he endured seven failed IVF/ICSI cycles over two and a half years.

Key revelations in this episode: 

• How he spent three days on his living room floor reading 100-200 scientific abstracts when clinics offered only "eat a balanced diet" 

• The remarkable discovery of secret support messages written by men inside clinic sample collection rooms 

• Why his evidence-based concerns about DNA fragmentation and varicocele were repeatedly dismissed 

• The life-changing investigation with Dr. Jonathan Ramsey and varicocele embolization with Dr. Steven Moser

Alasdair's persistence transformed his outcomes dramatically. His sperm count improved from 200,000 to 7-8 million, with total motile sperm count reaching above 40 million, leading to natural conception of two daughters. Now running Green Man Vitality, he provides evidence-based fertility information to help other men.

About the Podcast

The Male Fertility Podcast
The UK’s leading podcast on male fertility. Real stories, expert advice, and the conversations men aren’t having.
The Male Fertility Podcast is the UK’s leading show dedicated to male fertility, hosted by Ciaran and Shaun, two men who’ve lived the reality of infertility diagnoses, fertility treatment, and everything that comes with it.

Whether you’re dealing with low sperm count, poor motility, low morphology, azoospermia, or a varicocele diagnosis, this podcast is the resource you wish you’d had from day one.

Each episode covers what actually matters: IVF and ICSI from the male perspective, navigating NHS referrals and waiting lists, the real cost of private treatment in the UK, lifestyle changes that can improve sperm quality, and the emotional and mental health impact that often goes unspoken.

We speak to fertility specialists, urologists, andrologists, and men sharing real, unfiltered stories — from difficult diagnoses through to successful pregnancies.

Topics we cover:

Male factor infertility: diagnosis and treatment options
Sperm health: count, motility, morphology, DNA fragmentation
IVF, ICSI, MESA, TESE, micro-TESE
Varicocele surgery and recovery
Supplements, diet, exercise, and lifestyle changes
Mental health, relationships, and coping strategies
NHS vs private fertility treatment in the UK
Costs, funding, and access to treatment
Supporting your partner
Real stories and success journeys

This podcast exists because male fertility is too often overlooked. Half of all infertility involves a male factor, yet most support is aimed elsewhere. We’re changing that.

If you’re facing fertility challenges, or supporting someone who is, subscribe now — you’re not alone.
