Fatherhood Begins Before Birth

What's happening

A major review published in The Lancet reveals that men's health before conception significantly impacts pregnancy outcomes and the health of future children. Smoking, obesity, high blood pressure, and alcohol consumption alter sperm in ways that influence fetal development. Global sperm counts have halved between 1973 and 2018. Fathers' heavy drinking may independently cause Fetal Alcohol Syndrome, a link only recently discovered.

The review also found that emotional support and practical involvement from partners during pregnancy lead to healthier outcomes. Researchers are calling for men to be included in pre-conception health guidelines for the first time. "What we have not had our eye on is how the health of the father impacts pregnancy and child health," said Tim Moss of Healthy Male. A companion study of 5,000 people across multiple countries found the same priorities everywhere: physical health, mental health, stability, and partner support.

What the text says

Psalm 139 is one of the most intimate texts in Scripture. The psalmist describes God's knowledge of the human body as something woven, crafted, knitted together in hidden places.

Psalm 139:13-1613For you formed my inmost being. You knit me together in my mother's womb.14I will give thanks to you, for I am fearfully and wonderfully made. Your works are wonderful. My soul knows that very well.15My frame wasn't hidden from you, when I was made in secret, woven together in the depths of the earth.16Your eyes saw my body. In your book they were all written, the days that were ordained for me, when as yet there were none of them.

The Hebrew word raqam, translated "woven," is a textile term. It describes the intricate, deliberate work of an artisan creating embroidery. The psalmist is saying that the formation of a human being is a work of art.

What the Lancet study reveals is that this work of art has more contributors than we assumed. The father's body, his habits, his health, his choices in the months and years before conception become part of the material from which the child is formed. The weaving begins earlier than anyone thought, and it involves more hands.

Paul extends this theology of the body in his letter to the Corinthians.

1 Corinthians 6:19-2019Or don't you know that your body is a temple of the Holy Spirit which is in you, which you have from God? You are not your own,20for you were bought with a price. Therefore glorify God in your body and in your spirit, which are God's.

The instruction was never merely about personal piety. Your body is a temple because what you do with it echoes beyond yourself. The Lancet findings are the scientific confirmation of what the text always implied: the body is communal. Its consequences are generational.

The reflection

The cultural habit of placing all reproductive responsibility on women has a quiet corollary: men's bodies are their own business. The science says otherwise. So does the text. Psalm 139 never specifies which parent's body the weaving metaphor applies to. The knitting is the work. The material comes from both. A father's health before conception is part of the tapestry his child will wear for life. Fatherhood begins with how a man treats his own body, long before he holds his child.
