Ranjith Ramasamy is a consultant urologist at Jumeirah American Clinic in Dubai, UAE, [3] [4] and the former Director of the Reproductive Urology Fellowship program at the University of Miami's Miller School of Medicine. [5] [6] [7]

Contents

An American medical researcher and urologist, Ramasamy is known for academic contributions to reproductive medicine, including testosterone deficiency, regenerative therapy, erectile dysfunction, and prostate cancer studies. [8] [1] Ramasamy has co-authored a significant number of publications in the domain of male infertility and sexual dysfunction. [9] [10] Ramasamy is a recipient of the American Society for Reproductive Medicine Award. [11]

Education

Ramasamy graduated with a B.S degree in Cell Biology and Neuroscience from Rutgers University in 2003. He continued to study at Rutgers, receiving his medical degree there in 2007. Ramasamy completed his urology residency training at Weill Cornell Medicine and NewYork-Presbyterian Hospital in 2013. He did his medical research on a fellowship, sponsored by the National Institutes of Health, in Male Reproductive Medicine and Microsurgery at Baylor College of Medicine in 2015. [12] [13]

Career

Since 2005, Ramasamy has contributed to medical research and publications in medical journals on the subject of Leydig stem cells, Testosterone Deficiency, Regenerative therapy, erectile dysfunction, prostate cancer, among others. [8] His main research areas of interests are in male infertility and sexual dysfunction. [10] [9] [14]

In 2020-21, Ramasamy contributed to research of coronavirus impact on male fertility and sexually transmitted diseases. [15] [16] [17] [18]

Ramasamy has been instrumental in creating a urology app intended to prepare medical students and trainees for urology board examinations. [19] He also serves as a reviewer for medical professional journals, including European Urology , Fertility and Sterility , The Journal of Urology , BJU International , Urology , the Indian Journal of Urology , and others [14]

Ramasamy has been among the first urology specialists to research and discover the impact of Covid-19 on male infertility and erectile dysfunction. His work, along with other researchers, has been published in The World Journal of Men's Health, [20] contributed to understanding of the COVID-19 infection and its relation to causing the underlying endothelial dysfunction, a condition in which the small blood vessels fail to perform normally and damage male erectile system. [21] [22] [16] [17]

Ramasamy is also a recipient of the 2019 George Paff Teaching Award of Excellence for teaching urology to Miller School of Medicine students. [23]

Ramasamy also found and validated that males who have recovered from SARS-CoV-2 acute phase are unlikely to be a source for sexual transmissions of SARS-CoV-2. Further investigation into sperm parameters before and after the COVID-19 mRNA vaccine was published in JAMA Network in 2022. [24] [25]

In September 2021, based on the previous work "Phase II Randomized, Clinical Trial Evaluating 2 Schedules of Low-Intensity Shockwave Therapy for the Treatment of Erectile Dysfunction", [26] Ramasamy became a principal researcher for the “Combined Shockwave Therapy and Platelet Rich Plasma for the Treatment of Erectile Dysfunction” study that is funded by a three-year grant provided by the National Institutes of Health. [27]

In 2023, Ramasamy received the Gold Cystoscope Award for creative impactful work in andrology, mentorship, clinical scholarship and research. [2] [28]

Erectile dysfunction (ED), also referred to as impotence, is a form of sexual dysfunction in males characterized by the persistent or recurring inability to achieve or maintain a penile erection with sufficient rigidity and duration for satisfactory sexual activity. It is the most common sexual problem in males and can cause psychological distress due to its impact on self-image and sexual relationships.

Andrology is a name for the medical specialty that deals with male health, particularly relating to the problems of the male reproductive system and urological problems that are unique to men. It is the parallel to gynecology, which deals with medical issues which are specific to female health, especially reproductive and urologic health.

<span class="mw-page-title-main">Epididymal hypertension</span> Condition that arises during male sexual arousal when seminal fluid is not ejaculated

Epididymal hypertension (EH), informally referred to as blue balls for males or blue vulva for females, is a harmless but uncomfortable sensation in the genital regions during a prolonged state of sexual arousal. It usually resolves within hours unless relieved through an orgasm.

Hypogonadism means diminished functional activity of the gonads—the testicles or the ovaries—that may result in diminished production of sex hormones. Low androgen levels are referred to as hypoandrogenism and low estrogen as hypoestrogenism. These are responsible for the observed signs and symptoms in both males and females.

<span class="mw-page-title-main">Testicular atrophy</span> Reduction in the size and function of the testicles

Testicular atrophy is a medical condition in which one or both testicles diminish in size and may be accompanied by reduced testicular function. Testicular atrophy is not related to the temporary shrinkage of the surrounding scrotum, which might occur in response to cold temperature.

Sexual medicine or psychosexual medicine as defined by Masters and Johnsons in their classic Textbook of Sexual Medicine, is "that branch of medicine that focuses on the evaluation and treatment of sexual disorders, which have a high prevalence rate." Examples of disorders treated with sexual medicine are erectile dysfunction, hypogonadism, and prostate cancer. Sexual medicine often uses a multidisciplinary approach involving physicians, mental health professionals, social workers, and sex therapists. Sexual medicine physicians often approach treatment with medicine and surgery, while sex therapists often focus on behavioral treatments.

<span class="mw-page-title-main">Azoospermia</span> Medical condition of a man whose semen contains no sperm

Azoospermia is the medical condition of a man whose semen contains no sperm. It is associated with male infertility, but many forms are amenable to medical treatment. In humans, azoospermia affects about 1% of the male population and may be seen in up to 20% of male infertility situations in Canada.

Male infertility refers to a sexually mature male's inability to impregnate a fertile female. In humans, it accounts for 40–50% of infertility. It affects approximately 7% of all men. Male infertility is commonly due to deficiencies in the semen, and semen quality is used as a surrogate measure of male fecundity. More recently, advance sperm analyses that examine intracellular sperm components are being developed.

<span class="mw-page-title-main">Testicular sperm extraction</span> Surgical procedure

Testicular sperm extraction (TESE) is a surgical procedure in which a small portion of tissue is removed from the testicle and any viable sperm cells from that tissue are extracted for use in further procedures, most commonly intracytoplasmic sperm injection (ICSI) as part of in vitro fertilisation (IVF). TESE is often recommended to patients who cannot produce sperm by ejaculation due to azoospermia.

Fertility preservation is the effort to help cancer patients retain their fertility, or ability to procreate. Research into how cancer, ageing and other health conditions effect reproductive health and preservation options are growing. Specifically sparked in part by the increase in the survival rate of cancer patients.

FNA mapping is an application of fine-needle aspiration (FNA) to the testis for the diagnosis of male infertility. FNA cytology has been used to examine pathological human tissue from various organs for over 100 years. As an alternative to open testicular biopsy for the last 40 years, FNA mapping has helped to characterize states of human male infertility due to defective spermatogenesis. Although recognized as a reliable, and informative technique, testis FNA has not been widely used in U.S. to evaluate male infertility. Recently, however, testicular FNA has gained popularity as both a diagnostic and therapeutic tool for the management of clinical male infertility for several reasons:

  1. The testis is an ideal organ for evaluation by FNA because of its uniform cellularity and easy accessibility.
  2. The trend toward minimally invasive procedures and cost-containment views FNA favorably compared to surgical testis biopsy.
  3. The realization that the specific histologic abnormality observed on testis biopsy has no definite correlation to either the etiology of infertility or to the ability to find sperm for assisted reproduction.
  4. Assisted reproduction has undergone dramatic advances such that testis sperm are routinely used for biological pregnancies, thus fueling the development of novel FNA techniques to both locate and procure sperm.
