“…The mutations detected in region 11531-12040 are concordant with the haplogroup status, as originally inferred from HVS-I and HVS-II, i.e., the root of haplogroup R0 (embracing branches HV0 and H) is indistinguishable from rCRS within that fragment, haplogroup T2 bears the characteristic 11812 transition, and in haplogroup U6a1 the 16239 and 11938 transitions seem to be linked (26). Not a single occurrence of the 11994 transition was found here or in the mtDNAs of another 20 asthenozoospermic and 23 teratoasthenozoospermic men (27). Therefore C11994T cannot play a dominant role in oligoasthenozoopermy or other forms of asthenozoopermy, at least in Portugal, and it is therefore doubtful that this mutation should constitute the single cause in India.…”
