blastocyst looks like a solid ball of cells. If, however, it is cut in half, a fluid-filled cavity, the blastocoel, is revealed. A single layer of cells, the trophoblast, forms the outer layer of the blastocyst just inside the zona pellucida (Figure 10.1). A clump of cells near one end of the blastocyst underneath the trophoblast layer is called the inner cell mass (Figure 10.1). This group of cells gives rise to the embryo. It is also the source of embryonic stem cells (see Chapter 15). The

luteal phase (Figure 3.2) causes the corpus luteum to die. However, although injection of LH into a woman can prolong the life of her corpus luteum for a few days, it then dies anyway. The number of LH receptors in the human corpus luteum drops as this structure ages, which may play a role in its death. Changes in the secretion of prolactin could also influence the life of the human corpus luteum, but we know little about the role of this hormone in the menstrual cycle. Perhaps secretion of an

5α-reductase deficiency. You have learned in this chapter that 5α-reductase converts testosterone to dihydrotestosterone (DHT) in cells of male external genitalia as well as of the prostate and bulbourethral glands. In contrast, the male sex accessory ducts, as well as seminal vesicles, respond to testosterone directly (see Figure 5.9). Guevedoces males are genetic males (46:XY) who are born lacking one of the forms of 5α-reductase enzyme. Their testes secrete normal levels of testosterone, but
