Sooo Hormonal
This hypothalamic hormone stimulates the anterior pituitary to release both FSH and LH.
What is GnRH?
LH and FSH are made here.
What is the Anterior Pituitary gland?
Sperm gain motility and mature primarily within this structure, not in the testes themselves.
What is the epididymis?
Ovulation occurs at the end of this ovarian phase.
What is the follicular phase?
The stage in pregnancy is associated with the greatest risk of major developmental abnormalities because organ systems are forming.
What is the first trimester?
A tumor preventing the anterior pituitary from releasing LH in a male would most directly decrease production of this hormone.
What is testosterone?
These fingerlike projections at the end of the oviduct help guide the oocytes into the fallopian tube.
What are fimbriae?
This structure is formed by the union of the vas deferens and seminal vesicle and empties into the urethra.
What is the ejaculatory duct?
How long do egg cells stay viable after ovulation on average?
12-24 hours
The cervix dilates during childbirth to this diameter.
What is 10 cm?
The corpus luteum primarily secretes these two hormones after ovulation.
What are progesterone and estrogen?
Day(s) _______: The egg travels through the Fallopian tubes to the uterus. If the egg is not fertilized, the cycle will begin again.
What are days 15-28?

What is 5 days?
Basal body temperature tends to slightly increase after ovulation because of rising levels of this hormone.
What is progesterone?
The hormone hCG is important early in pregnancy because it maintains this structure.
What is the corpus luteum?

What is oxytocin?
Implantation of a blastocyst on the walls of a fallopian tube results in this.
What is an Ectopic Pregnancy?
A vasectomy is the cutting of this structure.
What is the vas deferens?
The end of menstruation and reproductive years.
What is Menopause?
Colostrum differs from mature breast milk because it contains especially high concentrations of these immune components.
What are antibodies?
Negative feedback from testosterone primarily acts on these two structures in the male endocrine pathway.
What are the hypothalamus and anterior pituitary?
Name of female gamete production process.
What is Oogenesis?
These cells within the seminiferous tubules support developing sperm cells and form the blood-testis barrier.
What are Sertoli cells?
The size of an egg cell.
What is 0.12 mm? (120 micrometers)
Although nutrients and gases cross the placenta, maternal and fetal blood normally do not directly mix because of this placental barrier.
What is the chorionic membrane?
