The article discusses the lack of research on how SSRIs, commonly prescribed antidepressants, affect the sexual development of teenagers, highlighting concerns about potential long-term sexual side effects in young people.
Researchers at Bar-Ilan University have developed artificial testicles from real mice testis in a step toward treating male infertility, with hopes of eventually helping men struggling to have children. The tiny laboratory "organoids" are seen as a promising model for basic research on testicle development and function, potentially leading to therapeutic applications for disorders of sexual development and infertility. This research could aid in understanding the mechanisms involved in sex determination and treating male infertility, which affects one in 12 men worldwide.
Researchers have gained exciting insights into the sexual development of Keichousaurus, an extinct marine reptile that lived 240 million years ago. The study focused on the species' sexual dimorphism, particularly the differences in bone structure between males and females. The research revealed that males grew larger and had more robust upper arm bones compared to females. Bone tissue analysis indicated differential deposition in males, resulting in a triangular cross-section, while females retained an oval cross-section. The study also found that rapid growth to puberty and changes in bone density after puberty corresponded to shifts in energy allocation from growth to reproduction. The findings shed light on the growth and reproductive strategies of this ancient reptile.
