Example Questions
Example Question #21 : Reproductive System
Which of the following structures does not contribute to the fluidity of semen?
Bulbourethral glands
Pituitary gland
Prostate gland
Seminal vesicles
Pituitary gland
There are three primary structures that contribute fluids to sperm in order to create semen in the body: the seminal vesicles, the prostate, and the bulbourethral glands. The pituitary gland has an impact on the development and maturation of sperm, but does not directly add fluid to semen.
Example Question #22 : Reproductive System
Which of the following is a function of the male reproductive system?
Production and storage of sperm, production of sex hormones, and delivery of sperm to the female reproductive system
Production of sex hormones
None of these answers
Production and storage of sperm
Delivery of sperm to the female reproductive system
Production and storage of sperm, production of sex hormones, and delivery of sperm to the female reproductive system
The male reproductive system has all of the functions indicated in the answer choices.
Example Question #23 : Reproductive System
Painful cramps during menstruation is known as which of the following?
None of these answers
Dysmenorrhea
Menarche
Amenorrhea
Mastodynia
Dysmenorrhea
Dysmenorrhea is a term used to describe painful cramps that are present during menstruation. In most cases, the cramps are cause by involuntary contractions of the uterus, which is a muscle. Amenorrhea describes the abnormal absence of a menstrual period. Mastodynia describes breast tenderness during menstruation. Menarche describes a female's first menstrual period.
Example Question #24 : Reproductive System
The discharge of sperm and semen from the male body is known as which of the following?
None of these answers
Transpiration
Ejaculation
Implantation
Fertilization
Ejaculation
Ejaculation is the act of ejecting sperm and semen from the male body. Fertilization and implantation are the first steps of pregnancy that occur inside the female body after sexual reproduction has begun. Transpiration is the evaporation of water from plant leaves.
Example Question #25 : Reproductive System
What hormone surges and causes the release of an egg from the ovary?
Estrogen
Progesterone
FSH (follicle-stimulating hormone)
LH (luteinizing hormone)
Prolactin
LH (luteinizing hormone)
At day 14 of a menstrual cycle, the LH surge begins, which causes the follicle to burst, resulting in ovulation. The LH surge is caused by a rise in estrogen, which causes the pituitary gland to release LH.
Example Question #26 : Reproductive System
Which of the following hormones is crucial for the maintenance of pregnancy?
LH
Cortisol
FSH
Progesterone
Estrogen
Progesterone
Progesterone ("pro-gestation") is responsible for the maintenance of a pregnancy. Initially, the corpus luteum secretes progesterone in preparation for pregnancy. Then, after fertilization, human chorionic gonadotropin (hCG) is released which causes the corpus luteum to keep secreting progesterone. The placenta takes over it's function after 6 weeks gestation.
