INTERCONVERSIÓN DE ESTROIDES Figure 10.1.5 Interconversion of steroids. The principal enzymes involved are shown.
SECRECIÓN DE GONADOTROFINAS DURANTE LA VIDA Figure 10.1.6 Gonadotrophin secretion throughout life.@@ The ratio of LH to FSH changes at different times in life. Male gonadotrophin levels do not show the female cycles.
ESTRUCTURA DEL TESTÍCULO Figure 10.1.7 The structure of the testis. A. Sagittal section of the testis and epididymis inside the scrotum. B. Cross-section of three seminiferous tubules showing the spermatogenic Sertoli cells and the testosterone-producing Leydig cells in the interstitium. C. Structure of the wall of the seminiferous tubule.
DESARROLLO DEL ESPERMATOZOIDE Figure 10.1.8 Development of a spermatozoon. The morphological changes that take place from spermatocyte to spermatozoon.
ESTEROIDOGÉNESIS TESTICULAR Figure 10.1.9 Testicular steroidogenesis
CONCENTRACIÓN PLASMATICA DE TESTOSTERONA EN EL HOMBRE Figure 10.1.10 Male plasma testosterone concentration. The change in plasma testosterone concentration during the life span of a normal human male.
EFECTOS ANDROGÉNICOS DE TESTOSTERONA EN EL HOMBRE Figure 10.1.11 Androgenic effects of testosterone in the male. DHT = dihydrotestosterone; O = oestradiol-17β; T = testosterone
ESTRUCTURA DEL OVARIO Figure 10.1.12 Structure of the ovary. Follicles are shown in different stages of development. All stages would not be present at the same time.
