- Which of the following is NOT one of the events leading to male sex-determination in humans? The Wolffian ducts are degraded. TDF and SF1 stimulate transcription of SOX9. Testosterone is produced, which stimulates the development of male reproductive structures and other male secondary characteristics. Mullerian-Inhibiting Hormone (MIH) is produced. The SRY gene is expressed to produce Testes-Determining Factor (TDF).arrow_forwardAfter learning about the reproductive systems, how would advise a couple with following concern: "If we do not want a baby for next two years, how can we calculate the safe sex period?" She shares that her cycle is regular but not standard 28 days long cycle (so the standard explanation form different sources won't work unless you think critically)! At what time of the female cycle is she most likely to prevent fertilization of her ovulated egg? Consider the fact that her cycle is not 28 days but longer or shorter (you pick). Do males have any time (in their cycle- if any) when their gametes would not be able to fertilize the egg? In other words when can intercourse lead to least chance of pregnancy? Feel free to check with your older friends, doctors, nurses, or anyone who you feel comfortable talking about this.arrow_forwardWhich of the following is/are true with regards to hormones in the reproductive tract?
