We present 2 cases of likely rare event. In case 1, 3^rd degree consanguineous marriage revealed inv(6) with same break points in parents who were found to be phenotypically normal. The same inv(6) being inherited in progeny but presented with low AMH (anti Mullerian hormone) and high level of FSH (follicular stimulating hormone) leading to polycystic ovarian syndrome/premature ovarian failure. In case 2, a couple was presented with 2^nd degree consanguineous marriage and referred for 2 recurrent/ missed abortions. The amounts of shared genes are suggestive of more lethal genetic outcomes and inferred endogamy is a major driver to reproductive fiascoes, the ancestries of which are deeply tied at the meiotic level.
