Natural Fertility
Natural fertility is a couple's own ability to conceive through natural conception.1 No eggs or sperm are removed. No egg is fertilized in a laboratory. No part of the reproductive system is bypassed. In healthy couples, the chance of pregnancy in a given cycle is about 20 to 25 percent. That chance declines with age. It also declines when a health condition goes untreated. Common causes include endometriosis, tubal disease, and cycles with poor ovulation.2 Male factors also contribute. A low sperm count and poor sperm motility, or movement, are well established.2 The role of sperm DNA fragmentation, damage to the DNA inside sperm, is less settled. A 2024 review of earlier reviews found the evidence weak and rated their quality as low.3 That review measured results from laboratory procedures, not natural conception. A high fragmentation result is a reason to continue the search for a treatable cause. RRM looks for the conditions that have lowered a couple's natural fertility and treats them. It does not replace physiology that can be supported with a laboratory step. Medicine, surgery, and cycle-timed care support conception through the couple's own bodies. Restoring natural fertility for couples who desire it is the main clinical goal of RRM.
