How many sperm do you need to get pregnant?
ilan ba puke mo (1)
On average, each time men ejaculate they release nearly how many?
100 million sperm
Normal sperm densities range from _______ to greater than ________ sperm per milliliter of semen
15 million, 200 million
full term of pregnancy in weeks and days
38-42 weeks or 266 days
1st trimester (weeks)
0-12
2nd trimester (weeks)
13-26
3rd trimester (weeks)
27-32
You are considered to have a low sperm count if you have fewer than _________ per milliliter or less than ________ total per ejaculate
15 million sperm, 39 million sperm
semen is also called
seminal fluid
Fluid that is eliminated from the male reproductive tract and that contains sperm cells which are capable of fertilizing the female’s eggs
semen
Semen also contains liquids that combine to form _________ which helps keep the sperm cells viable
seminal plasma
Pregnancy is also called as
gestation
It is the condition of having a developing
embryo and later a fetus within the
uterine environment after the union of an
ovum and a sperm.
pregnancy
the purpose of which is
to prepare an ovum for fertilization by
sperm and the uterus for implantation of a
fertilized egg.
menstrual cycle
Menstrual cycles are ___ days long on
average.
28
First 14 days
follicular phase
Last 14 days
luteral phase
is the release of eggs from the ovaries
also known as the fertile stage
Ovulation
ovulation occurs when the ovarian follicles rupture and release the secondary _____________ cells
oocytes ovarian
After ovulation, during the ________, the egg will be available to be fertilized by sperm
luteal phase
what happens during the follicular phase?
estrogen stimulates the hypothalamus to secrete gonadotropin-releasing hormone (GnRh) which causes the pituitary gland to release:
Follicle-stimulating hormone (FSH)
Prompts the growth of _____ follicles in the surface of the ovary. It stimulates the production of estrogen by the cells within the follicles
6-20
Both ______ and ______ stimulate the growth and maturation of the follicles
estrogen, FSH
On day 14 of the menstrual cycle, blood levels of ____ and ___ peak.
FSH, LH
roughly spheroid cellular aggregation set found in the ovaries
Ovarian follicle
Women begin puberty with about ________ follicles, each with the potential to release an egg cell (ovum) at ovulation for fertilization
400,000
cause the cells within the follicles to secrete progesterone
Luteinizing hormone
______ and _______ promt endometrium (uterine wall) to store nutrients and expand the growth of blood vessels and connective tissues
fuq: baquette
Estrogen, progesterone
to store nutrients, ready the uterus for possible pregnancy
begins after ovulation
Luteal phase
develops from the follicle that contained the ovum
his tissue secretes large amounts of progesterone and estrogen - further develops the endometrium
Corpus Luteum
what happens if the egg isn’t fertilized
- The production of hormones by the corpus luteum declines, and blood levels of progesterone and estrogen fall
- GnRH is able to stimulate FSH and LH for the next cycle
- Blood vessels in the endometrium constrict, allowing the uterine wall to release its outer layer in the menstrual flow.
- If hindi fertilize and nagka mens, that’s menstruation
what happens if the egg is fertilized
The ovum will implant in the lining of the uterus within 8 to 10 days
