The disease map

Disease moduleSpermatogenic failure 8 maps to a 1-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 spermatogenic failure 8 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

nuclear receptor subfamily 5 group A member 1 (NR5A1)NR5A1 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

A 2011 review states that medical treatment for men with primary spermatogenic failure remains largely ineffective. No treatments have consistently demonstrated efficacy, and it has not been possible to reliably identify patients likely to benefit. The review notes that empiric medical therapy has been largely replaced by assisted reproductive techniques.

A 2005 study in transgenic mice found that ectopic expression of a mutated Kit protein, Kit(D814Y), in spermatids produced malformations in mature spermatozoa and, in the most severe cases, sterility. The phenotype was accompanied by increased phosphorylation of PLCgamma-1 in spermatogenic cells. The authors propose that alterations of PLCgamma-1 activity are related to the abnormalities of spermiogenesis.

A 2021 retrospective study of 133 men aged 32 to 40 years examined the effect of myo-inositol, folic acid and cyanocobalamin on fertility rates and DNA fragmentation. One group of 44 men took these agents as monotherapy for three months; a second group of 42 followed a diet for three months; a third group of 47 received both the agents and the diet for three months. The study reports that the complex therapy (agents plus diet) was associated with increased sperm concentration, improved progressive motility, and a higher percentage of sperm with normal morphology. The authors state that preparatory therapy with myo-inositol in preparation for IVF helped improve embryo quality and increase pregnancy rates, and that the positive effect may be explained by a reduction in sperm DNA fragmentation. The study does not report the magnitude of these changes, nor does it provide pregnancy rates or blastocyst formation rates as concrete numbers.

What is still missing is a consistent, reproducible treatment for men with primary spermatogenic failure. The 2021 study is retrospective, unblinded, and lacks a placebo control; its findings need confirmation in a properly randomised trial with pre-specified endpoints. No molecular target has been validated in human patients, and no therapy has shown benefit in a large, multi-centre trial.

Medical therapy for spermatogenic failure

AbstractMedical treatment of men with primary spermatogenic failure remains largely ineffective in contrast to those with secondary testicular failure. Treatment has been attempted with a multitude of agents ranging from hormones to nutritional supplements (antioxidants). While some studies have demonstrated benefit to some treatments, no treatments have consistently demonstrated efficacy nor has it been possible to reliably identify patients likely to benefit. Idiopathic spermatogenic failure likely results from multiple discrete defects in sperm production that are as yet unidentified. A better understanding of these defects will yield more effective treatment options and appropriate triage of patients to specific therapeutic regimens. This review focuses on the rationale and current evidence for hormonal and antioxidant therapy in medical treatment of male infertility, spermatogenic failure in particular. Although empiric medical therapy for spermatogenic failure has been largely replaced by assisted reproductive techniques, both treatment modalities could play a role, perhaps as combination therapy.

Ectopic expression of Kit<sup>D814Y</sup> in spermatids of transgenic mice, interferes with sperm morphogenesis

AbstractKit is a receptor tyrosine kinase that plays a fundamental role during the development of germ cells. Additionally, a truncated product, tr-kit, expressed in haploid spermatids and mature spermatozoa can induce parthenogenetic activation when microinjected into mouse eggs, through the activation of PLCgamma-1. In this work, we induced ectopic expression of a mutated Kit protein, Kit(D814Y) during germ cell development. The in vivo expression of this mutant in spermatids produced malformations in mature spermatozoa, and in the most severe cases, sterility. Ultrastructural analysis indicated that condensing spermatids in the transgenic mouse presented a mislocalization of the manchette; a structure that has a crucial role during the elongation steps of spermiogenesis. This morphogenetic phenotype was accompanied by an increased phosphorylation of PLCgamma-1 in spermatogenic cells. Interestingly, we also found that, in wild-type testis, PLCgamma-1 is specifically phosphorylated in condensing spermatids, coincident with the timing of expression of tr-kit in spermiogenesis. We propose that alterations of PLCgamma-1 activity artificially promoted by ectopic Kit(D814Y) expression are related to the abnormalities of spermiogenesis. Our observations suggest that PLCgamma-1 activity could be involved in the shaping of spermatozoa.

The effect of preparatory therapy with myo-inositol on the outcome of infertility treatment by ART in men with low reproductive function

AbstractResearch objective: to study the effect of myo-inositol (MI), folic acid (FA) and cyanocobalamin in mono- and complex therapy on the classical fertility rates and the level of DNA fragmentation in sperm in men with low reproductive function, and on the results of the in vitro fertilization (IVF) programs performed in these patients.Materials and methods. A retrospective study of 133 patients aged 32 to 40 years was carried out for the period 2020–2021. All patients were divided into three groups: group 1 – 44 men who took MI, FA and cyanocobalamin daily as monotherapy for 3 months; group 2 – 42 patients who followed a diet to improve spermatogenesis for 3 months; group 3 – 47 men, for whom complex therapy was applied for 3 months: MI, FA, cyanocobalamin and diet.Results. The increase of sperm concentration in ejaculate, improvement of progressively motility of spermatozoa, and increase of the percent of spermatozoa with normal morphology in men with failures of reproductive function after the complex preparatory therapy are defined. The preparatory therapy for men with MI in preparation for IVF helps to improve the quality of embryos and increase the pregnancy rates in couples with male infertility due to the assisted reproductive technologies. The positive effect of preparatory complex therapy in patients with poor spermatogenesis on the blastocyst formation rates in IVF programs is shown.Conclusions. The positive effect of MI on the normal functioning of the reproductive system in men has been proven. The increase pregnancy rates in the IVF program after preparatory treatment of men with MI can be explained by its positive effect on reducing the level of DNA fragmentation of sperm.
