The disease map

Disease moduleMale reproductive system disease maps to a 32-gene Open Targets module — the target space DeCure's AI scientist screens approved drugs against.
DeCure.ai methodSignature reversal (LINCS) plus network proximity (STRING) rank already-approved drugs likely to perturb this module — the same engine that produces DeCure.ai's repurposing hypotheses.
Repurposing thesisScreening approved medicines against this disease module, then publishing the evidence for the strongest candidate. Known pharmacology and human exposure data make the first question sharper — they do not establish safety or efficacy in a new indication.

Current lead

No approved-drug candidate for male reproductive system disease is corroborated in the literature DeepSearch retrieved. Some conditions are managed with non-pharmacological care — a device, surgery or physical therapy — rather than a medicine; that may be the case here, or the literature we found may simply be too sparse yet to support a drug-repurposing angle.

Molecular view

peptidase D (PEPD)PEPD is one of the genes genetically linked to this disease in Open Targets — shown as context, not as a drug target we're pursuing: no approved-drug candidate for this disease is yet corroborated in the literature we found.

What the evidence adds up to

Male infertility accounts for roughly half of all infertility cases. A 2020 clinical guideline from the AUA and ASRM, based on literature from 2000 to 2019, states that male contributions to infertility are prevalent and that specific treatments plus assisted reproductive techniques are effective at managing the condition. The guideline covers medical therapies, surgical techniques, and use of intrauterine insemination, in vitro fertilisation, and intracytoplasmic sperm injection. A 2010 review notes that men with impaired reproductive potential often benefit from directed medical therapy targeting endocrine anomalies, infection or inflammation, ejaculatory dysfunction, and erectile dysfunction. A 2022 review, however, states that currently available treatments are prohibitively expensive, difficult to obtain, require lengthy courses, and have many side effects; it suggests herbal therapy as a less expensive alternative with fewer side effects, but provides no clinical trial data or response rates.

The male reproductive system maintains an immunoprivileged environment to protect germ cells, but can be infected by microorganisms via haematogenous or ascending routes. A 2021 chapter describes how tissue-specific cells in the male system are equipped with pattern recognition receptors and negative regulatory systems; unrestrictive innate immune responses can disrupt immune homeostasis and lead to inflammatory conditions, which are an important cause of male infertility. A 2002 theoretical model proposes that sexually transmitted pathogens in the ejaculate trigger immune activity in the female reproductive tract, which may also attack spermatozoa, thereby setting up competition among sperm from different males to overcome those defences.

A 2023 book claims to cover recent advances in the male reproductive system, including physiological structure, function, aetiology, molecular mechanisms of common diseases, and evaluation and treatment, but provides no specific data or results. The 2020 guideline will undergo additional literature reviews and updating as knowledge expands.

What is still missing are large, well-funded randomised controlled trials comparing specific treatments—including herbal remedies—against placebo or standard care, with clearly defined outcomes such as live birth rates. Patient stratification by aetiology (e.g., infection, endocrine, genetic) is rarely performed in existing studies, and no single trial has sufficient power to guide individualised therapy. The cost and accessibility barriers noted in the 2022 review remain unaddressed by any published efficacy data.

Diagnosis and Treatment of Infertility in Men: AUA/ASRM Guideline PART II

AbstractPURPOSE: The summary presented herein represents Part II of the two-part series dedicated to the Diagnosis and Treatment of Infertility in Men: AUA/ASRM Guideline. Part II outlines the appropriate management of the male in an infertile couple. Medical therapies, surgical techniques, as well as use of intrauterine insemination (IUI)/in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) are covered to allow for optimal patient management. Please refer to Part I for discussion on evaluation of the infertile male and discussion of relevant health conditions that are associated with male infertility. MATERIALS/METHODS: The Emergency Care Research Institute Evidence-based Practice Center team searched PubMed®, Embase®, and Medline from January 2000 through May 2019. When sufficient evidence existed, the body of evidence was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, additional information is provided as Clinical Principles and Expert Opinions (table[Table: see text]). This summary is being simultaneously published in Fertility and Sterility and The Journal of Urology. RESULTS: This Guideline provides updated, evidence-based recommendations regarding management of male infertility. Such recommendations are summarized in the associated algorithm (figure[Figure: see text]). CONCLUSION: Male contributions to infertility are prevalent, and specific treatment as well as assisted reproductive techniques are effective at managing male infertility. This document will undergo additional literature reviews and updating as the knowledge regarding current treatments and future treatment options continues to expand.

Innate Immune Defense in the Male Reproductive System and Male Fertility

AbstractTo protect the male germ cells from adverse immune reaction, the male reproductive system adopts special immune environment such as immunoprivileged status. The male genital organs can be infected by various microorganisms via hematogenous dissemination and ascending genitourinary tracts. To overcome the immunoprivileged status, the male genital organs also adopt their own innate defense against microbial infection. The tissue-specific cells in the male reproductive system are well equipped with innate immune machineries, including pattern recognition receptors (PRRs) and their negatively regulatory system. PRR-initiated immune responses must be tightly regulated by the negative regulatory system for the maintenance of immune homeostasis. The immune homeostasis can be disrupted by unrestrictive innate immune response, which may lead to inflammatory conditions in the male genital tracts, an important etiological factor contributing to male infertility. This chapter describes the current understanding of the innate immune responses in the male reproductive system and their effects on male fertility.

Sperm competition promoted by sexually transmitted pathogens and female immune defences

AbstractIn this work I introduce the Sexually Transmitted Disease (STD)-mediated Sperm Competition Model that establishes a link between sperm competition among males, sexually transmitted (ST) pathogens carried by the ejaculate and immune defences against ST-pathogens and spermatozoa in the female reproductive tract. Increased immune activity in the female reproductive system triggered by ST-pathogens may also result in increased immune attack against spermatozoa, thus setting the stage for competition amongst spermatozoa of different males to overcome the immune defences of females. Successful spermatozoa will have improved competitive abilities at fertilizing ova.

Conventional treatment options and herbal remedies for male infertility

AbstractMale infertility is responsible for an estimated 50% of all cases of infertility. Treatments for male infertility include surgery, in-vitro fertilization, hormone therapy, and herbal remedies. Assisted reproductive technologies and methods have made it possible to identify and treat previously untreatable causes of male infertility. Currently available treatments for male infertility are prohibitively expensive, difficult to obtain, necessitate a lengthy course of treatment, and have a host of side effects. Herbal therapy offers male infertility treatment that is less expensive and has fewer side effects than other treatments. The current review focuses on the various treatment options for male infertility.
