I receive many patient referrals from GPs and understand how important it is for you to find the right person to help your patient.

Hopefully, the information elsewhere on my website has provided an overview of my experience, but if you would like further information you can access my full CV and find below a list of lectures that I have recently given on the field of urology, with a specialism in male fertility.

January 2020 saw me examining in Kuala Lumpa. I was on the speciality board in Urology, of the Joint Surgical Colleges Fellowship Examinations and really enjoyed the task.  

Patient Referrals

Should you decide that I am well-placed to help your patient there are several ways of referring them to me:

Consensus and Diversity in the Management of Varicocele for Male Infertility: Results of a Global Practice Survey and Comparison with Guidelines and Recommendations

Varicocele, defined as an abnormal enlargement and tortuosity of veins in the pampiniform plexus, is the most common correctable cause of male infertility. Varicocele affects nearly 15% of the general male population and is diagnosed in 19% to 41% of primary male infertility.


The relationship between genitourinary microorganisms and oxidative stress, sperm DNA fragmentation and semen parameters in infertile men

An imbalance in the genitourinary microbiome is emerging as a contributing factor to male infertility. The purpose of this study was to determine whether there is an association between genitourinary microorganisms and seminal oxidative stress, sperm DNA fragmentation and semen parameters.


Comprehensive Analysis of Global Research on Human Varicocele: A Scientometric Approach

This study provides a comprehensive analysis of research trends on the etiology, mechanisms, potential risk factors, diagnosis, prognosis, surgical and non-surgical treatment of varicocele, and clinical outcomes before and after varicocele re- pair. Varicocele is defined as an abnormal enlargement and tortuosity of veins in the pampiniform plexus. One in 7 adolescents over 15 years of age is reported to have a varicocele.


Sperm DNA Fragmentation: A Critical Assessment of Clinical Practice Guidelines

Sperm DNA fragmentation is implicated in male infertility and adverse reproductive outcomes. With the publication of many studies regarding the etiologies and contributors to SDF, guidelines are necessary to aid clinicians in the application of SDF for male fertility evaluation.


Male infertility

It is estimated that infertility affects 8–12% of couples globally, with a male factor being a primary or contributing cause in approximately 50% of couples. Causes of male subfertility vary highly, but can be related to congenital, acquired, or idiopathic factors that impair spermatogenesis. Moreover, numerous studies have found that in- creased SDF adversely impacts conception rates


Sperm DNA Fragmentation: A New Guideline for Clinicians

About 15% of infertile patients have a normal semen analysis. However, assessment of sperm concentration, motility and morphology may not fully reflect impaired sperm DNA integrity which is detrimental for normal fertilisation, embryo development and success of ART. Moreover, numerous studies have found that in- creased SDF adversely impacts conception rates

Male Infertility

In this chapter from the publication "Recent Advances in Endocrinology and Diabetes 1", my co-authors and I report on the main contributory factors to male infertility, and discuss the most appropriate ways in which to manage those suffering.

The semen microbiome and its impact on sperm function and male fertility: A systematic review and meta-analysis

Male factor is attributable in up to 50% of cases of infertility. In vitro studies demonstrate that bacteria can negatively impact sperm function. The use of next-generation sequencing techniques has provided a better understanding of the human microbiome.

Burdens and awareness of adverse self-reported lifestyle factors in men with sub-fertility: A cross-sectional study in 1149 men

There are no current pharmacological therapies to improve sperm quality in men with sub-fertility. Reducing the exposure to lifestyle risk factor (LSF) is currently the only intervention for improving sperm quality in men with sub-fertility.

Should the current guidelines for the treatment of varicoceles in infertile men be re-evaluated?

Published in March 2019, this review comprehensively evaluates the current indications for varicocele treatment, and it is proposed that these should be redefined in contemporary guidelines to reflect current advances in male fertility research.

Male Oxidative Stress Infertility (MOSI): Proposed Terminology and Clinical Practice Guidelines for Management of Idiopathic Male Infertility

Despite advances in the field of male reproductive health, idiopathic male infertility, in which a man has altered semen characteristics without an identifiable cause and there is no female factor infertility, remains a challenging condition to diagnose and manage.

A Comparison between two assays for measuring seminal oxidative stress and their relationship with sperm DNA fragmentation

Oxidative stress (OS) is a significant cause of DNA fragmentation and is associated with poor embryo development and recurrent miscarriage. The aim of this study was to compare two different methods for assessing seminal OS and their ability to predict sperm DNA fragmentation and abnormal semen parameters.

The role of sperm aneuploidy as a predictor of the success of intracytoplasmic sperm injection?

It has long been recognized that chromosomal abnormalities are more frequent in sperm from subfertile men than in the general population with a consistent finding in the published literature of a predominance of sex chromosomal anomalies.

Novel use of COMET parameters of sperm DNA damage may increase its utility to diagnose male infertility and predict live births following both IVF and ICSI

Male infertility has become the most common cause of a couple’s difficulties in conceiving a child and is reported to be the most common cause of fertility cycles being carried out, yet, most men presenting with infertility are not thoroughly investigated before they embark on infertility treatment.

A Global Survey of Reproductive Specialists to Determine the Clinical Utility of Oxidative Stress Testing and Antioxidant Use in Male Infertility

Globally, infertility impacts 15% of couples trying to conceive. The incidence of male infertility has been increasing over the past several decades, ranging from 20% to 70% worldwide. The male partner is found to be solely responsible in 20%–30% of cases, and contributes to couple infertility in approximately 50% of cases

Microdissection testicular sperm extraction for men undergoing cancer treatment

Where cryopreservation of a good quality semen sample is not possible or was not offered prior to initiation of treatment, microdissection testicular sperm extraction (mTESE) offers a potential route to biological fatherhood. This review explores current evidence supporting the use of mTESE in patients treated for cancer, as well as some of the barriers and questions that still remain before this technique can form part of routine practice.

Sperm Vitality and Necrozoospermia: Diagnosis, Management, and Results of a Global Survey of Clinical Practice 

perm vitality testing is a basic semen examination that has been described in the World Health Organization (WHO) Laboratory Manual for the Examination and Processing of Human Semen from its primary edition, 40 years ago. 


Mixed Sertoli cell only histology and NOA

Likelihood of sperm retrieval is increased four-fold when Sertoli-cell only histology is observed in combination with another histological pattern during microdissection testicular extraction (mTESE) for non-obstructive azoospermia.

  • My husband, William Ford, saw Dr Ramsay in 2020 for treatment for sperm DNA fragmentation. Following his advice and a small procedure we finally had a successful round of ICSI and our son Theodore was born in November 2021. To our enormous surprise I fell pregnant entirely unexpectedly and naturally in the summer of 2023 and we welcomed our second son, Hector, last week. We wanted to say a huge thank you to Dr Ramsey for his part in this. Fertility treatment can feel very ‘production factory’ but we really felt that Dr Ramsey cared deeply about our situation and that his advice was specific to us. Clearly it was very successful!

    Thank you
  • Following the positive results of my FNA procedure, I went for a private semen analysis yesterday evening, which came back as positive for sperm in my semen.

  • My husband saw Mr Ramsay due to fertility issues. He was commenced on Tamoxifen 20mg once a day which was then reduced to every second day due to his bloods. We went on to have successful ICSI treatment and our daughter has now been born
    Our daughter has now been born
  • Following our appointment, in which you shared the excellent news regarding the improvement in Ross' DNA fragmentation, we embarked on our third ICSI cycle. I am now 15 weeks pregnant with 2 reassuring scans under our belt.

  • Andrew and I saw you a few times last year when you diagnosed and treated Andy's varicocele. Earlier this year, we had an unsuccessful (2nd) IVF ICSO attempt and were preparing for our 3rd when we discovered I had fallen pregnant naturally in March. I am very pleased to let you know that I am now nearly 11 weeks pregnant! 
    I am now 11 weeks pregnant!
  • I am delighted to be writing to tell you that our beautiful baby girl was born on 20th January. You may remember we saw you around this time last year after we had a DNA fragmentation result of 98% and were referred to you.

  • Dear Mr Ramsay, early days yet but we were due to see you this month to look again and see how he's getting on with the meds you prescribed. However, I found out that I'm about 5 weeks pregnant. I literally can't believe it! After 4 years of being told 'you can't have children' and after a round of failed IVF, 2 months of your help and I'm pregnant. Naturally too!
    Im Pregnant. Naturally!
  • “We saw Mr Ramsay after our first failed cycle. In my eyes he's amazing. Such a lovely man. He took the time to take a full history and examine my husband (which no-one had done before) and treated him for an infection. Our fertilisation rate went from 40% with low grade embryos to 80% with top-grade embryos.
    Life has been busy since we’ve had a baby boy
  • My husband was under Jonathan Ramsay - he is a lovely man and certainly think he is regarded as the best in the UK.
