 the ovaries are directly attached to the Fallopian tubes.
. normally, only one follicle develops into a mature ovum in the ovaries per cycle normally.
 follicle stimulating hormone (FSH) stimulates the development of a follicle.

If the number of Sertoli cells decreased in a male’s testes, which of the following effects would occur?
Select one:
Body changes for puberty would be delayed, and testosterone would decrease.
The hypothalamus would enter hyperactivity, and GnRH levels would increase.
The man’s sperm count would decrease, and FSH levels would increase.
The testes would decrease in size, and LH levels would decrease.
 
 
Decreased immunity is a symptom of HIV/AIDS. This is caused by which of the following?
Select one:
 HIV destroys antigens. This decreases the possibility of recognizing pathogens in the future.
. HIV attacks the macrophages. Pathogens cannot be destroyed once they enter the body.
 HIV attacks the helper T cells. This allows pathogen cells to enter the body unnoticed.

Read the following statements related to the human papillomavirus and select the perspective it exemplifies in the drop-down menu. 

A parent of a Grade 5 student may feel that HPV immunization is offered too early and would encourage earlier sexual activity.   Answer social cultural ethical economic HPV vaccination costs approximately $525, but it is free for all girls in Grade 5 to 12 as it is most effective when administered to those who have not been exposed to human papillomavirus yet.    Answer social cultural ethical economic HPV vaccine has already reduced the rate of cervical cancer by half. Providing HPV vaccines to all students in Grade 5 will greatly reduce the number of cases of cancer in Alberta in the future.    Answer social cultural ethical economic If most of the girls in the target ages are vaccinated, they would provide a herd immunity for the rest of the population. If less than half of the girls in the target population are vaccinated, then the boys need to start getting vaccinated.    Answer social cultural ethical economic

The Seventh Generation Principle of the Iroquois states that the decisions we make today should lead to a sustainable future for the next seven generations. If the HPV vaccination is implemented for the next 40 years, it is predicted to eradicate all cancers caused by HPV.

A number of STIs are asymptomatic (present no symptoms). Therefore, affected persons can carry a disease without knowing they have it. Which of the following statements consider the economic perspective of carrying an STI for a time without knowledge of it?
Select one:
People who have contracted hepatitis B could be asymptomatic. This could cause them to transfer the disease without knowing it through sexual contact.
 Gonorrhea can spread to the joints. People who have affected mobility often need the help of their family to help them survive.
If a person does not know they have syphilis and become pregnant, the developing embryo could have birth defects.
Untreated chlamydia can cause PID. This increases the number of annual patient referrals to the infertility clinic, which then increases the demand of the already low number of fertility specialists in Alberta.

Although the most effective forms of oral contraceptive for women contain estrogen and progestin, some birth control pills contain a small dose of progestin only. This is because there are many risks and side effects associated with estrogen.Which of the following statements is NOT a reason for using a progestin-only oral contraceptive?
Select one:
 Progestin-only oral contraceptives prevent the production of FSH and LH in the anterior pituitary.
 Prgesterone suppresses the production of GnRH in the hypothalamus.
Progesterone suppresses the maturation of follicles, thereby preventing ovulation of a mature ovum.
Progesterone maintains the corpus luteum as corpus luteum releases a large amount of progesterone and some estrogen.
