Category: Human Reproductive system-Menstrual cycle
- menstruation
- ovulation
- fertilization
- implantation
- directly kill the sperm in the testes
- cause negative feedback, reducing the FSH and LH needed for spermatogenesis
- block the vas deferens
- make the seminal fluid too acidic
- vasectomy
- hysterectomy
- oophorectomy
- mastectomy
- zona pellucida
- antrum
- corpus luteum
- polar body
- FSH and LH to the gonads
- GnRH to the anterior pituitary
- testosterone into the bloodstream
- estrogen to the uterus
- within the testes
- posterior to the urinary bladder
- surrounding the urethra at the base of the bladder
- at the base of the penis
- corpus cavernosum
- corpus spongiosum
- tunica albuginea
- glans penis
- ovary
- fallopian tube
- cervix
- abdominal cavity
- thinking estrogen levels are low and increasing the secretion of FSH and LH
- thinking progesterone levels are high and stopping the cycle
- triggering immediate ovulation
- thickening the endometrium
- stimulate the pituitary to release more LH
- maintain the corpus luteum, which continues to produce progesterone
- trigger the onset of labor
- prepare the breasts for lactation
- ureter
- ejaculatory duct
- vas deferens
- urethra
- four equal-sized haploid cells, while oogenesis produces one large haploid cell and smaller polar bodies
- one large cell and three polar bodies, while oogenesis produces four equal cells
- diploid cells, while oogenesis produces haploid cells
- two cells, while oogenesis produces four
- blocking the sperm from entering the uterus
- destroying the oocyte before it can be fertilized
- preventing ovulation by suppressing FSH and LH release
- making the endometrium too thin for implantation
- low testosterone and underdeveloped secondary sexual characteristics
- high testosterone and low sperm count
- normal testosterone but no sperm
- high sperm count and low testosterone
- hormonal surges
- peristaltic contractions of the tube wall
- movement of the fimbriae
- the suction from the uterus
- progesterone, estrogen
- estrogen, progesterone
- LH, FSH
- FSH, LH
- nourish sperm
- cause uterine contractions
- lubricate the distal urethra and neutralize acidic urine prior to ejaculation
- form a clot in the semen after ejaculation
- follicle that fails to rupture and release its egg
- degenerated corpus luteum
- primary oocyte
- blockage in the fallopian tube
