Hormones
The 2 parts of the body that produce hormones during the onset of puberty
Hypothalamus and Pituitary gland
Reason why the testes are housed outside the body
keeps sperm at the correct low temperature
The human ovum is about ---- which is large enough to be seen by the naked eye
1/10mm
Uterus is only receptive to implantation for a short time usually about ----- days after implantation
7
Permanent option to avoid pregnancy
Sterilization
Causes the leydig cell to secrete testosterone
Luteinizing hormone (LH)
Name the tubules are considered as
Sperm factories
The part of the ovary which houses developing eggs
Cortex
The layer that sheds if an egg is not fertilized
Endometrial
New organ that develops in the uterus
Placenta
Triggers sertoli, to release androgen-binding protein or ABP which binds to the testosterone creating large local concentrations which triggers the production of sperm
Follicle stimulating hormone(FSH),
The stem cells that set the sperm making process in motion by dividing, even before puberty begins
Spermatogonia
Females are born with essentially all of the early versions of eggs in all of the primordial follicles they will ever have, around a ------- at the time of birth
Million
Amount of sperm that can make their way into a female reproductive organ
Millions
Name of the developing baby at the end of week 8
Fetus
Gets the follicle to finally complete meiosis 1
LH-(luteinizing hormone)
Type of spermatogonia that get pushed down the tubule and become primary spermatocytes
B
Typically delayed until puberty for females
Oogenesis(egg creation)
Produced when the male and female pronuclei meet
Diploid zygote
When all organ systems are present in a developing baby
Week 9
Produced by the implanted blastocyst and causes the corpus luteum to continue producing progesterone
hCG-(Human chorionic gonadotropin)
Spermatids have all the genetic information they need, but they are not yet
Mobile
All layers of uterus
Endometrium, myometrium and perimetrium
Instructions that cells receive
Divide, differentiate, develop
Size of a typical non-pregnant female's uterus
A fist
