Reproductive Biology Quiz & Flashcards

The LH surge triggers ovulation, unlike progesterone, testosterone, or oxytocin.

Fertilization occurs in the fallopian tubes; they do not transport sperm or produce estrogen.

A zygote is formed immediately after fertilization, not a blastocyst, embryo, or fetus.

The epididymis stores and matures sperm, while the testes produce sperm.

The placenta provides nutrients to the fetus, not the other functions listed.

The luteal phase prepares the uterine lining, unlike the other phases.

The cortical reaction prevents polyspermy, not the other processes.

Progesterone maintains pregnancy, unlike estrogen, testosterone, or FSH.

The corpus luteum secretes hormones after ovulation to support pregnancy.

Fraternal twins result from two different eggs being fertilized by two different sperm.

The scrotum regulates temperature for optimal sperm production, not the other functions.

Amniotic fluid cushions the fetus, rather than providing nutrients or removing waste.

Seminiferous tubules in the testes are where sperm production occurs.

A drop in estrogen and progesterone triggers menstruation, not an increase in these hormones or testosterone.

Blocked fallopian tubes can cause infertility, not excessive testosterone or low sperm count.

The pill thickens cervical mucus and prevents ovulation to prevent pregnancy.

Meiosis allows for genetic diversity in gametes, unlike mitosis or fertilization.

Sertoli cells provide nourishment to developing sperm unlike the other structures.

Estrogen thickens the uterine lining, not the other functions listed.

IUDs primarily prevent fertilization or implantation, not by hormone release or mucus thickening.

Capacitation is the process by which sperm become capable of fertilizing an egg.

Progesterone maintains the uterine lining during the luteal phase.

The acrosome contains enzymes necessary for penetrating the egg.

Condoms are a barrier method, unlike pills, IUDs, or patches.

Estrogen is responsible for female secondary sexual characteristics, not testosterone.

The vas deferens transports sperm from the epididymis to the urethra.

HCG is detected in pregnancy tests, indicating pregnancy.

The menstrual phase involves shedding the uterine lining, unlike other phases.

The prostate gland secretes fluid for semen, not sperm production or storage.

A vasectomy involves cutting the vas deferens to prevent sperm transport.

Testosterone is not directly involved in the menstrual cycle, unlike FSH, LH, and estrogen.

Ovulation occurs during the ovulatory phase, not egg maturation or shedding.

The acrosome helps penetrate the egg's layers, not storing energy or genetic material.

HCG is the hormone detected in pregnancy tests, not LH, FSH, or progesterone.

Identical twins occur when a single fertilized egg splits, not from two separate eggs.

The epididymis is where sperm maturation occurs, not the vas deferens or others.

Oxytocin induces labor contractions, aiding childbirth.

The rhythm method involves tracking the menstrual cycle to avoid fertile days.

A sharp rise in LH triggers ovulation, unlike estrogen or progesterone.

Testes produce sperm, unlike storing or supporting embryos.

The follicular phase involves follicle development, not the luteal or menstrual phases.

Seminal vesicles secrete fluid that is part of semen, not storing or producing sperm.

Condoms block sperm from entering, not by killing sperm or altering hormones.

Testosterone is crucial for male secondary characteristics, not estrogen or progesterone.

FSH stimulates egg maturation, unlike triggering ovulation or maintaining pregnancy.

The cervix acts as a barrier to infections, not producing eggs or supporting fetal development.

Identical twins share the same DNA, unlike fraternal twins.

Oogenesis is the development of eggs, unlike embryo implantation or fertilization.

The luteal phase involves thickening of the uterine lining, not shedding or ovulation.
