*Partition separates testis into two compartments
*Produce androgens (testosterone)
*produce approx 5mill sperm daily
Term

*abdominal
*fetal development
Term
Testes contain ________ ______ where _______ takes place.
Definition
*seminiferous tubules
*spermatogenesis
Term
Spermatogenesis Purpose=
Definition
produce haploid gametes for sexual reproduction

*spermatozoa
*epididymis
Term
Sperm DO NOT become mobile/active/functional until ________.
Definition
Capacitation
Term
Capatcitation=
Definition
mixing with secretions from seminal vesicles and exposure to conditions in female reproductive system
Term
secretion from _______ prevents premature capacitation.
Definition
*epididymis
Term
Sperm movement through ductus defernes via _______

Term
Ampula
Definition
*expanded area in ductus deferens prior to seminal vesicles
*sperm can be stored in ampula deactivated from months
Term
Post seminal vesicles and prostate gland =
Definition
*ejaculatory duct = seminal vesicles -> prostate -> urethra in penis
Term
Accessory glands (male)
Definition
*seminal vesicles
*prostate gland
*bulbourethral gland (Cowpers)
Term
They secrete (3) and propel sperm and semen through _____________ (contraction)
Definition
*secrete fluids that activate sperm
*secrete fluids that provide nutrients for motility (frucotose)

*ejaculatory duct
Term
Seminal fluid (semen)=
Definition
fructose, hormones, buffers, clotting proteins
Term
Penis=
Definition
tubular organ with urethra passing through
Term
Penis function:
Definition
* passage of urine to environment
*introduction of semen/sperm into female reproductive system (joining of gametes)
Term
Body of penis mostly ________ tissue
Definition
*erectile tissue
Term
Nervous system release of NO which:
Definition
*Relaxes arteriole muscles = blood vessels dilate
*Blood flow increases
*Vessels become engorged with blood
*Erection occurs
Term

Oogenesis=
Definition
production of mature ovum for potential fertilization
Term
At puberty, ______ triggers Ovarian cycle.
Definition
FSH
Term
Uterine tubes function

Term
Proliferaion phase
Definition
restoration of endometrium due to estrogen secretion
Term
Secretory phase
Definition
