SummaryThe contraceptive method used during lactation should be chosen on the basis of (a) effectiveness in preventing pregnancy and (b) its effect on lactation. Combined hormonal contraceptives affect lactation adversely due to the oestrogen component. Progestogen-only contraceptives may increase the quantity and quality of milk yield during lactation. In the present study the effects of four progestational drugs used immediately after delivery were investigated. No adverse effect on initiation of lactation was found. The side effects of the drugs are reported. No pregnancies were reported during the period of the study.

The effect of four progestational drugs on the amount of milk yield in a group of lactating Egyptian women was estimated during the first year of lactation. The milk yield was highest in the women given Depo-Provera, followed by those receiving Deladroxone and quingestanol acetate. Only in those women given chlormadinone acetate was the milk yield, on average, lower than in the control group of non-medicated women.

The milk yield in a group of lactating Egyptian women was estimated during the first twelve post-partum months. It increased from the second to the seventh month, then dropped gradually in the last four months. The best milk yield was found in women aged 20–30 years, with a parity of two to four and an inter-delivery interval of 30–36 months. (Summary in Arabic, p. 401.)

The effects of four progestational drugs on the composition of human milk during the first year of lactation were studied in Egyptian women. In comparison with a group of non-medicated women, chlormadinone acetate, Depo-Provera and Deladroxone all caused a marked increase in protein content in the early stages of lactation; quingestanol acetate had little overall effect. The lipid and lactose content showed irregular changes in the medicated groups as compared with the controls.

The composition of human milk during the first year of lactation was studied. The effect of age, parity and the length of inter-delivery interval on the composition is described. Of the three parameters, the length of inter-delivery intervals was the most important, while the other two were weakly correlated. (Summary in Arabic, p. 409.)
