Some research suggests a link to reproductive function because the melanocortin pathway can influence GnRH secretion via leptin signaling. However, the evidence for a direct, clinically actionable role of MC4R variants in human fertility is weak. Most associations come from animal models or mechanistic studies; human GWAS show small effect sizes that are often not replicated. MyBody-X does not offer a specific MC4R test in the fertility context. Even if a DNA test covers MC4R, its interpretation for individual fertility counseling is not evidence-based. Clinical factors such as hormone levels, cycle regularity, and sperm quality are far more relevant. Therefore, the evidence level is mechanistic/unclear. Be cautious of marketing claims that label MC4R as a 'fertility gene'.","area":"gesundheit","canonical_id":"gesundheit:canonical-60f5316a52c10cc70e793d39","id":"public-15bc300da4f8ab10d92e44ee","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: MC4R in the context of fertility","score":22.64753625,"snippet":"MC4R (melanocortin 4 receptor) is primarily known for its role in appetite regulation and energy balance.

Variants such as rs17782313 are strongly associated with obesity. In the context of fertility, MC4R is part of the leptin-melanocortin pathway that modulates GnRH release and thus the hypothalamic-pituitary-gonadal axis. However, direct evidence linking MC4R variants to human fertility outcomes is limited. Most data come from animal studies or indirect associations via obesity-related infertility. The evidence is therefore mechanistic rather than clinically established. Consumer DNA tests may include MC4R in obesity panels, but fertility claims are not supported by robust human data. MyBody-X does not appear to test MC4R based on the provided context. Safety note: No direct risks, but avoid overinterpretation.","area":"gesundheit","canonical_id":"gesundheit:canonical-29c220d2265a358dd429e5f1","id":"public-c979f38bcea899b30607e70c","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: MC4R in the context of Fruchtbarkeit","score":22.33153367,"snippet":"MC4R encodes the melanocortin 4 receptor, a key regulator of energy balance and appetite.

The MyBody-X Longevity DNA Test analyzes genetic variants linked to aging, metabolism, and oxidative stress – topics that may indirectly affect reproductive health. However, evidence for a direct connection between these SNPs and fertility is weak. Fertility is determined by a complex interplay of hormones, lifestyle, environment, and medical factors. Existing studies (e.g., on FTO or MC4R) show only small metabolic effects, not on conception ability. The test cannot diagnose fertility issues or replace fertility treatment. The evidence grade is therefore 'marketing/unclear', as claimed links are not backed by specific fertility studies. Clinical validation is lacking.
