Overview
- The Bundesinstitut für Bevölkerungsforschung analyzed pairfam data tracking 1,862 women from three birth cohorts over ten years.
- Within that period, 28% reported infertility and 9% reported at least one miscarriage, capturing incidence rather than a single-point snapshot.
- Age was the dominant factor, with 47% of women aged 35 and older experiencing fertility barriers and only 8% in that group reporting a birth without such difficulties.
- During the main family-forming years from the mid‑20s to mid‑30s, 63% had at least one child, yet roughly a third still encountered barriers.
- Germany’s average age at first birth has risen to about 30.4 years, and clinical commentary highlights that assisted reproduction has declining success with age, significant costs, and insurance coverage often limited to under 40.
