Zusammenfassung
Das Reproduktionsverhalten in der westlichen Gesellschaft hat sich in den letzten
zwei Jahrzehnten sehr verändert. Elternschaft wird oft spät und zeitlich genau geplant.
Tritt eine Konzeption trotz regelmäßigem Verkehr in der fruchtbaren Zeit nicht im
ersten halben Jahr ein, liegt möglicherweise bereits eine Subfertilität vor. Trotzdem
erreicht die Lebendgeburtenrate bei unbehandelten, subfertilen Paaren fast 55 % in
36 Monaten (Alter 29,1 ± 4,5). In dieser Zeit kann „fertility awareness“ mit Natürlicher
Familienplanung (NFP) die einzig nötige Strategie sein, um Paaren mit guter Prognose
zu helfen, die auch bei Therapie keine höhere Aussicht auf eine Schwangerschaft hätten.
Überstürztes Eingreifen bei „unerfülltem Kinderwunsch“ kann hier eine unnötige Überbehandlung
bedeuten.
Abstract
Reproductive patterns have evolved dramatically in many developed countries over the
last two decades and parenthood is now often planned. Most pregnancies occur during
the first 6 months of unprotected intercourse. Thereafter subfertility is assumed,
although life-birth rates in untreated subfertile couples are nearly 55 % in 36 months.
Couples with a reasonably good prognosis can use conventional (natural) methods of
fertility awareness during this period because treatment does not improve conception
rates and early intervention for presumed infertility may represent overtreatment.
