“…24,25 Women tend to have larger glands than men, with additional transient increases during pregnancy and early postpartum period. [26][27][28] The results of the present study show no group mean differences in the pituitary volume between patients with SAD and healthy volunteers in winter or summer. These findings are in agreement with those reported by Schwartz et al, 17 describing similar results of pituitary size in patients with SAD.…”

“…Correspondingly, the volume of the pituitary underlies pregnancy- and lactation-associated changes. Although the pituitary enlarges during the course of pregnancy, probably due to hyperplasia of PRL cells [62], it decreases up to eight month after delivery in humans [63–65] or, respectively, seven days after delivery in rodents [66–68], when the number of PRL cells reaches prepregnancy levels [69]. Similar effects have also been observed in the MPOA and SON of pregnant/lactating rats.…”

The time of pregnancy, birth, and lactation, is characterized by numerous specific alterations in several systems of the maternal body. Peripartum-associated changes in physiology and behavior, as well as their underlying molecular mechanisms, have been the focus of research since decades, but are still far from being entirely understood. Also, there is growing evidence that pregnancy and lactation are associated with a variety of alterations in neural plasticity, including adult neurogenesis, functional and structural synaptic plasticity, and dendritic remodeling in different brain regions. All of the mentioned changes are not only believed to be a prerequisite for the proper fetal and neonatal development, but moreover to be crucial for the physiological and mental health of the mother. The underlying mechanisms apparently need to be under tight control, since in cases of dysregulation, a certain percentage of women develop disorders like preeclampsia or postpartum mood and anxiety disorders during the course of pregnancy and lactation. This review describes common peripartum adaptations in physiology and behavior. Moreover, it concentrates on different forms of peripartum-associated plasticity including changes in neurogenesis and their possible underlying molecular mechanisms. Finally, consequences of malfunction in those systems are discussed.

“…Children and elderly people were not included in our subjects. The size, shape, and signal intensity of the normal pituitary gland changes dramatically depending on age or physiologic status, [20][21][22] and the pituitary stalk may show similar changes. This will be a subject for future investigation.…”
