101. What is meant by the negative feedback loop for females and for males? How does it operate? Describe its similarities and differences between females and males.
The negative feedback loop regulates the production of the sex hormones estrogen and progesterone in females and testosterone in males. It is also known as the HPG axis, that is, the hypothalamus-pituitary-gonad axis. In males, the pituitary’s production of luteinizing hormone (LH) stimulates the testes to produce testosterone. When testosterone levels are high, the hypothalamus reduces its production of gonadotropin-releasing hormone (GnRH), which causes the pituitary to reduce the production of LH, consequently reducing production of testosterone by the testes. When testosterone levels fall, the hypothalamus increases the production of GnRH and the process starts again.
In females, the negative feedback loop functions in a similar fashion and the levels of estrogen and progesterone are regulated by hypothalamus, pituitary, and ovaries.

102. Describe the process of sex differentiation of the gonads of males and females.
In the 7th week after conception, the sex chromosomes direct the gonads to begin differentiation. In the male, the undifferentiated gonad develops into a testis at about 7 weeks. In the female, the process occurs somewhat later, with the ovaries developing at around 13 or 14 weeks. An important gene that directs the differentiation of the gonads, located on the Y chromosome, is called SRY, for sex-determining region, Y chromosome. If SRY is present, it causes the manufacture of a substance called testis-determining factor (TDF), which makes the gonads differentiate into testes, and male development occurs.

103. Describe the role of the Müllerian ducts and the Wolffian ducts in the female and the male, respectively.
The Müllerian ducts and the Wolffian ducts are both related to the process of prenatal sexual differentiation. Once the gonads have differentiated into testes and ovaries in the male and female respectively, these organs begin to produce different sex hormones which direct the differentiation of the rest of the internal and external genital system. The Müllerian ducts and the Wolffian ducts are found in both males and females, however, in females, the Wolffian ducts degenerate and the Müllerian ducts turn into the fallopian tubes, the uterus, and the upper part of the vagina. In the case of males, the opposite occurs. The testes secrete the Müllerian inhibiting substance (MIS) which causes the Müllerian ducts to degenerate, while the Wolffian ducts turn into the epididymis, the vas deferens, and the ejaculatory duct.

104. Discuss the problems that may occur in the passage of the testes through the inguinal canal. How can these problems be corrected?
Two problems may occur in this process. First, one or both testes may fail to descend into the scrotum by the time of birth, a condition known as undescended testes, or cryptorchidism. This condition occurs in about 3 percent of all males. Most frequently, only one testis is undescended, and the other is in the normal position. In most of these cases, the testes do descend by the first birthday. If the testes do not descend spontaneously, however, the condition is usually corrected by surgery. The optimum time for doing this is soon after the first birthday. Otherwise, if both testes fail to descend, the man will be sterile, because the high temperature of the testes inside the body inhibits the production of sperm. Undescended testes are also more likely to develop cancer. The second possible problem occurs when the inguinal canal does not close off completely. It may then reopen later in life, creating a passageway through which loops of the intestine can enter the scrotum. This condition, called inguinal hernia, can be remedied by simple surgery.

105. Explain what homologous and analogous organs are. Give at least two examples of each.
Homologous organs refer to the organs in the male and the female that develop from the same embryonic tissue. Analogous organs, on the other hand, are the organs in the male and the female that have similar functions.
Examples of analogous organs include the testes in males and the ovaries in females, both of which develop from the gonads. The glans penis in males and the clitoris in females are also homologous to one another in that they both develop from the genital tubercle. The testes and the ovaries, and the glans penis and the clitoris are also examples of analogous organs as they perform similar functions. The testes and the ovaries are both responsible for producing sex hormones, while both the glans penis and the clitoris play important roles in producing sexual arousal.

106. Compare the two intersex conditions of congenital adrenal hyperplasia (CAH) and androgen-insensitivity syndrome (AIS).
In congenital adrenal hyperplasia (CAH), a genetic female develops ovaries normally as a fetus, but in the course of prenatal development, the adrenal gland begins to function abnormally and produces an excess amount of androgens. Prenatal sexual differentiation then does not follow the normal female course. As a result, the external genitals are partly or completely male in appearance—the labia are partly or totally fused so there is no vaginal opening, and the clitoris is enlarged to the size of a small or full-sized penis.
In androgen-insensitivity syndrome (AIS), a genetic male produces normal levels of testosterone, but as a result of a genetic condition, the body tissues are insensitive to the hormone and prenatal development is feminized. The individual is born with the external appearance of a female: a small vagina and undescended testes.

107. Changes that occur to the body during puberty are sometimes difficult for adolescents in the American society. Why are they difficult and what would you suggest as possible solutions to some of the problems?
Unlike in other parts of the world where puberty rites are performed to signify an adolescent’s passage to adulthood, in American culture, an individual’s entry into puberty is not given any formal recognition. In the absence of such rituals, a person may think that his or her body is doing strange things, making puberty a particularly difficult time. This problem can be overcome by providing timely education to adolescents about their bodies and the changes that will take place.

108. Discuss the common problem of painful menstruation.
The most common menstrual problem is painful menstruation, called dysmenorrhea. Symptoms of this may include cramping pains in the pelvic region, headaches, backaches, nausea, and a feeling of pressure and bloating in the pelvis. Dysmenorrhea is caused by prostaglandins, hormone-like substances produced by many tissues of the body, including the lining of the uterus. These prostaglandins can cause smooth muscles to contract and can affect the size of the blood vessels. Women with severe menstrual pain have unusually high levels of prostaglandins which cause intense uterine contractions and choke off some of the supply of oxygen-carrying blood to the uterus. Prostaglandins may also cause greater sensitivity to nerve endings. The combination of the uterine contractions, lack of oxygen, and heightened nerve sensitivity produces menstrual cramps.

109. Do women’s moods change over the menstrual cycle? Explain your choice of answer.
Women do, on average, experience some fluctuations in mood over the phases of the menstrual cycle. According to research, women generally have positive moods around the time of ovulation and experience anxiety, irritability, depression, fatigue, and headaches premenstrually. However, there is a great deal of variation from one woman to the next in the size of these shifts and the way they are expressed. Some women experience no shifts, or shifts so slight that they are not noticeable, while others experience large shifts. Also, there is some ambiguity regarding the manner in which these shifts should be interpreted—whether women are unusually “low” premenstrually or unusually “high” around the time of ovulation.

110. Discuss the biological and psychological cycles that are present in men.
A study found that men’s testosterone levels displayed weekly fluctuations, peaking on weekends. Men who had a female partner and wished to have a child with her displayed a 28-day cycle of testosterone levels, leading the researchers to hypothesize that the men’s hormone cycles might have synchronized with their partner’s. Strikingly, men’s testosterone levels also vary with sexual activity. In this same study, men who had sex with an unfamiliar partner showed a 100 percent increase in their testosterone levels the following morning.
