This was a cross-sectional study carried out on 462 pregnant women attending antenatal care in Ibadan, Nigeria. The study's aims were to assess the level of participation of Nigerian men in pregnancy and birth, the attitude of the women and likely targets for improved care delivery. Three hundred and forty-nine women (75.5%) were aware that husbands could participate in childbirth. Most women did not think it was their husbands' place to attend antenatal clinic (48.3%) or counselling sessions (56.7%). Nearly all husbands (97.4%) encouraged their wives to attend antenatal clinic – paying antenatal service bills (96.5%), paying for transport to the clinic (94.6%) and reminding them of their clinic visits (83.3%). Three hundred and thirty-five husbands (72.5%) accompanied their wives to the hospital for their last delivery, while 63.9% were present at last delivery. More-educated women were less likely to be accompanied to the antenatal clinic, while more-educated men were likely to accompany their wives. Yoruba husbands were less likely to accompany their wives, but Yoruba wives with non-Yoruba husbands were 12 times more likely to be accompanied. Women in the rural centre were less likely to receive help with household chores from their husbands during pregnancy, while educated women were more likely to benefit from this. Monogamous unions and increasing level of husbands' education were associated with spousal presence at delivery. It appears that male participation is satisfactory in some aspects, but increased attendance at antenatal services and delivery would be desirable.
