Abstract
The effect of sex of the newborn infant on milk composition was studied by analyzing milk for various constituents (lactose, total protein, lipids and minerals) at different stages of lactation (colostrums, transitional and mature milk). This was done in an attempt to clarify a belief in the early days of the Islamic State that mothers who give birth to males produce concentrated milk compared with those giving birth to females. Milk samples were collected at Khartoum Teaching Hospital from mothers that delivered male infants (50 samples), and female infants (50 samples), were analyzed for lactose, total protein, lipids and various minerals including Ca, P and Mg. Colostrums from the group that delivered male infants was significantly higher in the concentrations of lactose (P < 0.001), Ca (P < 0.001) and Mg (P < 0.001), as well as having higher specific gravely (P < 0.001) compared with that produced by mothers who delivered females. However, concentration of P of the transitional milk of those who delivered male ones was significantly higher (P < 0.001) compared with those who delivered females. Concentration of total proteins and cholesterol in both groups decreased with progress in lactation, while concentration of triglycerides of the two groups increased with progressing lactation.
