How may the effect of estrogen on breast tissue differ during lactation?

During lactation, the influence of estrogen on breast tissue is indeed minimal compared to its effects during other stages of a woman’s lifecycle, such as puberty or pregnancy. Estrogen plays a crucial role in the development of breast tissue and the regulation of the menstrual cycle, but its levels significantly fluctuate. During lactation, high levels of prolactin and oxytocin take precedence in stimulating milk production and ejection, respectively.

While estrogen is present during this time, its roles are overshadowed by other hormones that directly impact lactation processes. Estrogen’s ability to promote breast tissue growth and differentiation is reduced, as the primary focus shifts to breastfeeding. Therefore, the effect of estrogen on the functional aspects of breast tissue during this period is significantly less pronounced, leading to the conclusion that its role is minimal during lactation.

The other options address either physiological processes not primarily influenced by estrogen during this time or functions that don't directly relate to its effects on breast tissue during lactation.
