OÖGENESIS
Egg forming cells (oöcytes) go through
two divisions
1º = primary
2º = secondary
•Starts with a 2n=46 1ºoöcyte
that divides, resulting in two n=23
cells, but one is a large 2º oöcyte
and one is a small 1st polar body
that may itself divide
•Second division only occurs if
2º oöcyte is fertilized. Results in
one large n=23 ovum (egg) and
one small n=23 2nd polar body
•Thus oögenesis results in one
large fertilized egg (zygote) and
possibly three small polar bodies
OÖGENESIS – OÖGONIA TO OÖCYTES
Germ cells from yolk sac migrate to ovary and
become potential egg cells called oögonia
 In fetus, millions of oögonia produced by mitosis
but most of them degenerate (atresia)
 Some develop into immature egg cells called
primary oöcytes during fetal development

 200,000
to 2 millions present at birth
 40,000 remain at puberty but only 400 mature during
a woman’s reproductive life

Each month about 20 primary oöcytes become
secondary oöcytes but usually only one survives to
be ovulated from Graffian follicle
OVARIAN FOLLICLES

HUMAN
SEXUALITY
MODULE 4
SEX AND GENDER
Sex
 refers
to the distinct biological differences between male
and female.
 It is determined by the genitals and chromosomes.
 It begins at conception.
Gender
characterizes how a particular person presents
oneself in a culture (gender role)
 how one identifies himself/herself based on mental
awareness (gender identity)

GENDER IDENTITY




Socially constructed
Usually assumed that a person is of the gender that
corresponds to his/her sex: males are masculine, females
are feminine
Men are traditionally expected to be strong, independent,
dominant and aggressive
Women are seen as passive, dependent, subordinate, and
nurturing
SEX AND GENDER ARE NOT
ALIGNED
LGBT (lesbian, gay, bisexual, and
transgender)
-a person does not exhibit the typical
definitions of a male or female, called
INTERSEX
HUMAN SEXUALITY
Sexuality




the expression of the sex
The sphere of interpersonal behavior, especially
between the male and the female
Most directly associated with resulting to genital union
It attracts a man and a woman towards each other to
procreate and fulfill each other
LIBIDO/SEX DRIVE



ensures the continuation of the species
It triggers the desire, orchestrates the physiological
changes in the human body to produce egg and sperm,
maintain pregnancy, and foster nurturing instincts that
care for and protect the offspring
Can be a source of pleasure and fulfillment as well as
heartbreak and loss, even violence.
SEXUAL ACT




“Sexual intercourse”
Physical union of male and female through which human
beings procreate
Characterized by the penetration or insertion of the penis
into the vagina
Culminates in orgasm in which the penis ejaculates semen
with sperms into the vagina
SEXUAL EXPERIENCE AND
RESPONSE DEPENDS ON:




Nervous system: triggers the excitement, hormonal
secretions, orgasms and ejaculation
Circulatory system – causes blood to accumulate in the
genetal areas, making them swell
Muscular system – the muscle of thighs, buttocks, uterus
and vagina contract
Norepinephrine – causes a calm feeling of well being and
relaxation
ATTITUDE TOWARDS SEX AND SEXUAL
ACTIVITY


It is everyone’s duty to protect his/her sexual
integrity from fancies, words, actions,
pornography, and violence that make sex trivial
One should not allow the act of sexual intercourse
and expressions of the libido to be subject to
importunate curiousity and unwarranted intrusions
by others
ATTITUDE TOWARDS SEX AND SEXUAL
ACTIVITY



Sexual attraction, even satisfaction, should not be
mistaken for true love
Sexual activity should be performed rationally,
responsibly, respectfully, and consensually
Good sex happens at the right time, with the right person,
and for the right reason
ATTITUDE TOWARDS SEX AND SEXUAL
ACTIVITY



Heterosexual marriage is the most common adult expression
of sexuality… but many alternative exist:
- celibacy for religious reasons
- singleness by choice
- polygamy
- same sex partnership
No single profile predicts a happy, healthy, and fulfilling sex
life.
Personal attitudes, parents, family, love and God all
contribute to achieve it
 Do
you think human sexuality
is different from animal
sexuality? If so, in what way
do they vary?
-begins when a sperm successfully fertilizes an egg
From Egg and Sperm to Zygote
 Oogenesis refers to the production or
development of a mature egg from one of
the hundred thousands of oocytes
(immature eggs) to become a mature egg.
 Oogenesis begins before birth but
ovulation occurs once a month from
puberty to menopause.
 Ova are viable and can be fertilized, for
approximately 24 hours after ovulation.
 Spermatogenesis is the maturation of the
immature sperms inside the testes.
 Sperms are released into the male duct
system
 Immature to mature sperm takes about
53 days, starts at puberty continuing
throughout life.
 Sperms are viable for 72 hours and believe
to have maximum fertilizing capacity for
only 24 hours.
Fertilization
 starts when a million of sperms are ejaculated into the
vagina during intercourse
 out of millions, only few (thousands) of sperms can
survive the acidity of the vagina and swim upward
through the movement of their flagella-uterus-fallopian
tube to meet the egg
 it takes 15 minutes for the sperm and egg to meet to 3 days
 Zona pellucida is the capsule that surrounds the egg
where the sperm penetrates.
 once the sperm and the egg merge it results to a zygote
with a 46 chromosomes (23 from each parent)
 male offspring=ovum is fertilized by a Y sperm
 zygote is formed= series of cell divisions start=single
celled zygote transform into many cells to give rise to
the future embryo and placenta
 it remains in mobile state travelling from the fallopian
tube to reach uterus in 3-4 days
Monozygotic Twins
(Identical Twins)
 One egg is fertilized by one
sperm
 Embryo splits into two
during the early stages of
development
 Have identical genes and
must be of the same sex
Dizygotic Twins
(Fraternal Twins)
 Two eggs are ovulated and
each is fertilized by a
sperm cell
 No more genetically similar
than any other sibling in
the family (can be
same/different sexes)
 Maternal age, use of
assisted reproductive
technologies are factors
Conjoined Twins
 occurs when a mitotic division is incomplete
From Conception to Birth
Implantation
Period of the Zygote
Period of the Embryo
Period of the Fetus
Implantation
 After approximately a
week (6-7 days), the
developing embryo is
implanted into the uterus
 Zygote during this time
takes the form of
blastocyst with an inner
cell mass (future embryo)
and an outer cell mass
(future placenta)
Period of the Zygote
Period of the Zygote
 Placenta is formed from both mother and fetal tissues as
early as 1 week
 Placenta is a temporary disc-shaped organ that connect the
fetus to the uterine wall
 Placenta=the life support system for developing
fetus=passageway transfer for nutrients, waste & chemicals
between the mother and the fetus by osmosis and diffusion
 Human chrorionic gonadotropin (HCG) hormone is
produced
 During early pregnancy, HCG stimulates the
corpus luteum to enlarge to support the
uterus and zygote until the placenta takes
over
 HCG detection is the basis for pregnancy
test
 Placenta secretes its own hormones to support the
pregnancy and play a role in labor, lactation and
breastfeeding.
 Cord is the connecting link between the fetus and the
placenta
 Continuous and purposefull cell division and cell
differentiation reslts in the development of the
embryonic membranes & different germ layers that
give rise to specific organs and body systems at the 3rd
week
Period of the Embryo
 From 4th to 8th weeks of development=
embryo
 Body parts are formed during this period
 Critical time because viruses, drugs, and
inadequate nutrition can gravely affect the
embryo's development
Prenatal Structures
Period of the Fetus
 From 9 weeks after conception to birth
 Increase in size and systems begin to function
 Fetus rests in a pale straw-colored liquid the
amnion filled with amniotic fluid
 Age of viability: 22 to 28 weeks
First Month
 By the end of the
first month, the
embryo is about 1/10
of an inch long. The
heart, which is no
larger than a poppy
seed, has begun
beating.
First Month
Two Months
 The embryo is about
1 inch long and has
distinct, slightly
webbed fingers.
Veins are clearly
visible. The heart
has divided into right
and left chambers.
Two Months
Three Months
 By now the fetus is 2 1/2
to 3 inches long and is
fully formed. He has
begun swallowing and
kicking. All organs and
muscles have formed
and are beginning to
function.
Four Months
 Your baby is covered
with a layer of thick,
downy hair called
lanugo. His
heartbeat can be
heard clearly. This is
when you may feel
your baby's first
kick.
4 months
Five Months
 A protective coating
called vernix caseosa
begins to form on baby's
skin. By the end of this
month, your baby will be
nearly 8 inches long and
weigh almost a pound.
Six Months
 Eyebrows and
eyelids are visible.
Your baby's lungs
are filled with
amniotic fluid, and
he has started
breathing motions. If
you talk or sing, he
can hear you.
6 Months
Seven Months
 By the end of the
seventh month, your
baby weighs about 3
1/2 pounds and is
about 12 inches
long. His body is
well-formed.
Fingernails cover
his fingertips
Eight Months
 Your baby is gaining
about half a pound
per week, and
layers of fat are
piling on. He has
probably turned
head-down in
preparation for birth.
He weighs between
4 and 6 pounds.
Nine Months
 Your baby is a hefty
6 to 9 pounds and
measures between
19 and 22 inches. As
he becomes more
crowded, you may
feel him move
around less.
The Mother
 No menstruation
 May feel the following: fatigue, light headedness, dizziness,
fainting, abnormal cravings, nausea and vomitting
(morning sickness)
 Can feel the movement of the baby from the 4th to fifth
month
 Later month the mother can experience: heaviness, swollen
legs, constipation, pelvic pains, frequent urination and
uterine contarctions
Influences on Prenatal
Development
 General Risk Factors
 Teratogens: Diseases, Drugs, and
Environmental Hazards
 How Teratogens Influence Prenatal
Development
 Prenatal Diagnosis and Treatment
General Risk Factors
Nutrition: adequate amount of food,
protein, vitamins, & minerals
Stress: decreases oxygen to fetus and
weakens mother’s immune system
Mother’s Age: neither too young, nor
too old
Teratogens
 Substances that may harm the
developing fetus and result in the
formation of birth defects
Teratogens: Diseases, Drugs, and
Environmental
Hazards
• Many diseases pass
through the placenta
directly and attack the
fetus
• Potentially dangerous
drugs not limited to
cocaine but include
alcohol and caffeine
• Environmental hazards
are treacherous because
we’re often unaware of
their presence
How Teratogens Influence Prenatal
Development
Not universally harmful
Harm particular structures at a
particular point in development in
particular animals
Effects of Teratogens
Fetal Alcohol Syndrome
Can result in mental retardation / learning disability
Facial Features
 Epicanthal folds
 Small, widely spaced eyes
 Flat midface
 Short, upturned nose
 Smooth, wide philtrum
 Thin upper lip
 Underdeveloped jaw
Cleft Lip / Palate
 maternal alcohol
consumption and
maternal smoking
during the early stages
of pregnancy have
been shown to increase
the risk of developing
orofacial clefts
Prenatal Diagnosis and
Treatment
Diagnosis: ultrasound, amniocentesis,
and chorionic villus sampling can
detect physical deformities and genetic
disorders
Treatment: fetal medicine and genetic
engineering are experimental
What is an amniocentesis?
 An amniocentesis is a test
that takes a small sample of
the amniotic fluid.
 involves putting a long, thin
needle through your
abdomen into the amniotic
sac.
 An amniocentesis is
generally offered to women
between the 15th and 20th
weeks of pregnancy who are
at higher risk for
chromosome problems.
 The test may have indicated
a higher risk for a
chromosome problem or
neural tube defect.
What is a chorionic villus sampling

a small tube (catheter) through
your vagina and into your cervix.
can be tested for chromosome
problems and some other genetic
problems.
test can also look for other genetic
problems and disorders if you have
a family history of them.
These other results also depend on
the lab doing the testing.
Unlike amniocentesis, CVS does
not give information on neural
tube defects such as spina bifida.
 may be offered if you are at higher risk for
chromosome problems.
 You may also be offered it if you have a family history
of a genetic problem that is testable from the
placental tissue.
 CVS is usually done between the 10th and 13th weeks
of pregnancy.
 For this reason, women who have CVS also need a
follow-up blood test between 16 and 18 weeks of their
pregnancy to screen for neural tube defects.
Approaches to Childbirth
• Childbirth classes provide
information about pregnancy
and childbirth
• Childbirth classes teach pain
control through deep
breathing, imagery, and
supportive coaching
• Mothers who attend classes
use less medication during
labor and feel more positive
about labor and birth
MODULE 5B
By taking the first
day of the woman’s
last menstrual cycle
and adding 280
days, you can
calculate when baby
is due to be born.
As the mother nears full term, several things happen:
Baby loses the lanugo covering

head becomes “engaged”.
Eye color is slate-blue or black,

and will not be fixed until after

is close at hand.
This is the correct term for the process of childbirth…the
emergence of a child from its mother’s uterus. It starts with a
signal from the pituitary gland. The hormone oxytocin is secreted
into the bloodstream of the mother, and the process begins.
(pitocin and syntocinon are common synthetic forms of this
hormone, used to induce labor) There are 3 stages of childbirth:
1.LABOR
2.BIRTH OF THE BABY
3.BIRTH OF THE PLACENTA
3 signals indicate that labor has begun…
1. Contractions begin
2. Mucous plug is dispelled
3. Amniotic sac breaks
1. Initial uterine
contractions are
short and mild, but
frequency,
intensity, duration
increase.
During transition
stage, the cervix
completes dilation
and stretches over
baby's head.
The entire process
usually lasts up tp
15 hours
2. The mucous plug
falls out as cervix
dilates; it is
accompanied by a tinge
of blood, and is referred
to as “bloody show”
3. Before labor begins, or in
the early stages, the amniotic
sac ruptures under pressure
and fluid trickles or gushes
out. Sometimes the sac must
be broken manually.
Prior to the beginning of labor, the thick
cartilage walls of the cervix begin to thin out
and lengthen.
This process is called
effacement. The cervix must be completely
effaced in order to fully dilate.
The purpose of “labor” is for the
muscles to contract, pulling open
the cervix. It must open (or dilate)
to 10 cm. (approximately 4 inches)
to allow for the birth of the baby.
This is hard and painful work for
the mother.
The red arrows point to the
cervical area and various
stages in becoming fully
effaced and dilated.
Aptly named, labor is hard work.
Contractions/dilation can be very painful. There
are several methods that can help the mother
manage the pain.
Although
medications can
control pain,
there is risk that
the baby will be
affected and
become groggy.
A regional anesthetic can be injected through
the vagina into a nerve to relieve pain, but an
epidural block is now the method of
preference. An injection into the spinal column
blocks pain. The mother remains awake.
The mother will need to attempt to control this pushing movement. A slow
expulsion of the baby from the vagina causes less damage to sensitive skin.
In the second stage of parturition, the baby is
expelled from the womb through the vagina
by both the uterine contractions and by the
additional maternal efforts of pushing or
"bearing down". When the head is first
visible, it is called “crowning”.
An episiotomy is an
incision through the
skin and muscles in
the perineum, made
during a vaginal
delivery. This
procedure is
performed in 2/3 of
US births, and allows
extra room for baby
to pass out of the
birth canal. The
incision prevents
tearing. It stitches
easier and heals
faster than a tear.
Vaginal delivery accounts for 3
out of every 4 births in the
United States.
Most remaining
vernix caseosa is
rubbed off during
delivery.

is one that is head-first!
The mother may stand with her legs apart,
squat, lean over, recline backward or lie down
with legs supported to facilitate the delivery.
When the amniotic sac has not
ruptured during labor or pushing,
the infant can be born with the
membranes intact. This is referred
to as “being born in the caul”. The
caul is harmless and it’s
membranes are easily broken and
wiped away. In medieval times, and
in some cultures still today, a caul
was seen as a sign of good fortune
for the baby, in some cultures was
seen as protection against
drowning, and the caul was often
impressed onto paper and stored
away as an heirloom for the child.
With the advent of modern
interventive obstetrics, premature
artificial rupture of the membranes
has become common and it is rare
for infants to be born in the caul in
Western births.
The "sutures" or
anatomical lines
where the bony
plates of the skull
join together can
be easily felt in
the newborn
infant. The
diamond shaped
spaces on the top,
top back, and
sides of the skull
are often referred
to as the "soft
spot" in young
infants…correctly
known as
fontanelles
(fontanels).
The fontanelles actually allow the skull to change to a new shape,
so it can emerge through the small cervical opening. This is called
“molding” of the head. This change in the shape of the skull will go
back to it’s original appearance in a few hours up to a few days.
Immediately following delivery, if not during, a bulb syringe is used to
suction mucous from the throat and nasal passages. It’s important that
those first breaths be deep and clear. Healthy, loud cries assure that!
The umbilical cord is connected at baby’s
navel. The cord must be clamped and cut. (or
tied off) Then another small plastic clamp is
used, placed close to baby’s tummy.
Stage 3 of childbirth follows delivery of the
baby…it is the delivery of the afterbirth.
After the placenta is delivered, it should be inspected for size, shape,
consistency, and completeness. A one minute, thorough examination to detect
normalcy or abnormalities may be critical in the management of mother and
baby. An abnormal placenta may be one of the first indications that mother or
baby has a problem.
A suctioning method or vacuum is sometimes used
to assist in difficult deliveries. It can turn the baby
to a better position or perhaps just quicken the
descent down the birth canal.
A breech birth position is
sometimes more difficult. It
means that the baby is in the
birth canal feet or buttocks first.
An instrument called a forceps is
sometimes used during delivery also.
The cushioned tongs are used to hold,
guide, or pull baby through the birth
canal to hasten delivery.
CAESARIAN SECTION
birth position
Also known as C-section or spelled cesarean section,
1. fetus is delivered through a horizontal incision in abdominal and uterine walls
2. advisable when: fetus in improperly aligned (such as a sideways position
called transverse position), multiple fetuses, fetal distress, mother is worn out, or
mother has a transferable genital condition or infection
Birth Complications
 Lack of oxygen (anoxia):
Often leads to surgical
removal of the fetus (Csection)
 Premature and Small-for-
date infants
 Prematurity is less serious
than small-for-date
Soon after birth,
information will be
gathered for baby’s
official birth certificate.
This becomes a matter of
permanent public record;
make sure it is correct,
including spellings! It’s
time to name the baby!
Identification wrist or
ankle bands are secured,
as well as foot prints.
The Newborn
 Assessing the newborn:
Apgar to assess newborns’
health; NBAS for a
comprehensive assessment
of infants
 4 primary states: alert
inactivity, waking activity,
crying, sleeping
 Half of newborns’ sleep is
REM (deep sleep)
 Putting the baby to sleep on
The hormone oxytocin that started the
process of childbirth has several other
effects on the body.
1. Research indicates that it plays a major
role in establishing maternal behaviors
in the mother.
2. Stimulates the muscles of the cervix,
vagina, and uterus, helping them
contract after delivery
3. Works in conjunction with a second
hormone secretion from the pituitary
gland, prolactin, to make and secrete
milk from the mammary gland of the
breast. This process is called lactation.
The first secretion from the breast is called
colostrum. It is sticky, and a milky-yellow
color. It not only provides baby with perfect
nutrition and is easily digestible, but also
contains immunities from the mother.
Breast milk
 best for the first 6 months of life
 protection againts infections, less allergy, healthier
growth, better neuro development & lower rates of chronic
disease
 economical & convenient

health institutions to adopt rooming-in
and breastfeeding practices.
Postpartum Depression
