Q

Describe the stages of conception:

A
  1. ovulation occurs: egg is released from the follicle, on approx. day 14 of the cycle.
  2. The egg is picked up by the fimbriae (finger like structures on the fallopian tube).
  3. Sperm travels through the cervix and uterus to one of the fallopian tubes (2 to 4 million). The egg must be fertilized with 12-24 hours or it will disintegrate.
  4. only 2-3 million sperm make it as far as the egg. Since gravity and they can only move 1-3cm every hour, 3000 times their length in distance by the time they reach the egg.
  5. Sperm follow chemical signals from the egg. The egg is surrounded by a nutritious fluid called the zona pellucida. Sperm has to dissolve the layer to penetrate it using hyaluronidase. This is called capacitation: removal of the plasma membrane overlying the sperm to allow for greater binding between the sperm and the egg.
  6. The moment conception occurs, the zona thickens to block out all other sperm. This occurs in the fallopian tubes.
  7. The zygote moves down to the uterus, taking about 5 days
  8. Zygote implants in the uterus

Q

Explain the difference between the morning after pill and the abortion pill?

A

You can take the morning after pill within 5 days after sex because of the long process stated above (the sooner you take it the better because this journey doesn’t take everyone 5 days).

The morning after pill is a high dose of regular birth control pills that make the sperm inhabitable.

BUT! if the zygote is already implanted it will not have any affect in which case you would need to take the abortion pill.

Q

What is basal body temperature? How is it used to detect pregnancy?

A

BBT: the lowest waking temperature.

An abrupt rise in body temperature about the time when ovulation should occur that stays elevated for 2 weeks indicates a high probability that a woman is pregnant. Usually .2 to .4 degree change. But only detectable if a woman was keeping track prior to becoming pregnant.

The rise is temperature is due to the progesterone secreted by the creation of the corpus luteum and later by the placenta.

Q

Chemical tests, how do they work?

A

Detect: Human Chorionic gonadotropin (HCG) in women’s urine. You can tell faster with blood because it takes a few.

You can tell this faster with a blood test because it takes longer to be present in urine.

Q

Explain the 1st trimester

A

The first 8 weeks of pregnancy is called the embryonic stage.

The placenta and amniotic sac develop

Develops major organs and systems, facial features, feet, hands

Becomes a fetus in week 9

Human physical characteristics develop towards the end, like limbs, digits, testicular tissue, finger nails, toenails - usually able to determine sex by ultrasound

Q

Is it safe to have sex while pregnant?

A

Yes, the amniotic sac protects the fetus as well as a mucus plug at the base of the cervix prevents the movement of bacteria.

Although, if there is a history of miscarriage doctors may tell women to obtain from sex so their orgasms don’t cause contractions early on.

Sexual desire and physiological response has been shown to increase during the second trimester and decrease in the first and third. Maybe because of nausea and then the sheer size of the baby.

The increase in blood to to breasts, pelvice and external genitals could cause discomfort and sensitivity or make sexual activity more enjoyable

Women who were more satisfied with their partner before pregnancy had greater sexual satisfaction than other women, lower rates of fatigue and more positive about becoming a mother.

Pregnancy is not found to be related to a increased number of problems related to sexual functioning `

Q

What is stage 1 of birth?

A

Average labour lasts 8.6 hours in a first pregnancy
o About half that time for subsequent pregnancies

Contractions (initially far apart and less frequent) dilate the cervix until it is fully dilated to 10 cm (go to hospital at 5cm), allowing the baby to pass through

Dilation is used to define the three phases of the first stage of labour.

  • Early phase: cervix dilates to 4cm; contractions every 15-20 minutes
  • Active phase: goes from 4-8cm, contractions are more frequent and intense
  • Final phase/transition: shortest & most difficult, lasts 30min or less. cervix dilates to 10cm

Q

What is stage 2 of birth?

A

The second stage begins when the cervix is fully dilated and the head starts to move into the vaginal canal.

It ends with the birth of the baby.

Women “bear down” to move the baby down the vaginal canal. For first pregnancies usually 80 min, 30min if not.

An episiotomy (incision of the perineum to help with passage of baby) used to be used to reduce tearing but has not been shown to be anymore beneficial.

Once baby is delivered, blood and mucous is sucked from the baby’s nose and mouth to induce breathing.

Babies who passes meconium (first stool) in utero to clear passageways.

Q

Explain C-sections and it purpose

A

The baby is delivered through an incision made through the abdomen wall of the uterus

There are many reasons for a C-section delivery:
o Baby is too large
o Mother’s pelvis is too narrow
o Baby is in a breech or transverse position
o Umbilical cord will pass through the cervix before the baby

There is evidence that c-sections are being performed way more often than they should be.

What did masters and johnson find in relation to women’s sexuality while breastfeeding?

A

Women who breastfed were more likely to have higher sexual interest but were more likely to delay resumption of intercourse

46
Q

Because of the role of oxytocin in contraction of the uterus during an orgasm, what might happen while a woman is breast feeding?

A

She may orgasm or experience sexual arousal during breastfeeding, but these contractions are working to move the uterus back to pre-pregnancy size

47
Q

Oxygen deprivation can occur, The physician may order a C-section

57
Q

Stillbirths

A
  • Stillbirths occurs when a baby is born dead within the last trimester of pregnancy
  • In developed countries, 5 in 1000 babies are stillborn
  • In undeveloped countries, it is 25 in 1000 babies

It can be very hard on relationships when there is a stillbirth. Especially if the mother blames herself, there is also the fact that milk comes in even though there is no baby.

Q

What are the numbers associated with infertility?

A

1 in 8 couples in Canada had infertility issues

Male infertility affects 1 in 2 men, usually due to low sperm count

Female infertility affects 1 in 12 women, most commonly due to irregular ovulation (normal range of ovulation is 21-36 days)

61
Q

What is the first step in fertility treatments?

A

The use of fertility drugs to help produce eggs faster and in larger numbers. May cause a woman’s ovaries to to produce as many as 40 eggs and go into super ovulation

clomid: The drug stimulated the pituitary gland to produce LH and FSH to produce ovulation

HMG: directly stimulated the ovaries to produce eggs

These drug increase the risk for multiple fetuses

62
Q

The assisted human reproduction act

A

helps in the maintenance of national standards and policies surrounding, eggs sperm and embryos in fertility clinics.

This restricts people’s ability to select for sex, transplant non-human egg/sperm, paying a donor, selling or cloning embryos.

63
Q

What is artificial insemination (AI)?

A

Uses a thin, flexible catheter to insert sperm directly into the vagina or uterus

Fertilizing them with sperm in the laboratory

Injecting fertilized egg into woman’s uterus

Have to take a ton of hormones prior

65
Q

What is Gamete intrafallopian transfer (GIFT)?

A

Eggs and sperm are collected and deposited directly into woman’s fallopian tubes, which allows for natural fertilization to occur and not the selection of the best egg.

66
Q

What is Zygote intrafallopian transfer (ZIFT)

A

o A fertilized egg is transferred directly to a fallopian tube to allow for natural implantation

  • The physician gradually dilates the cervix.
  • A small, hollow tube attached to an aspirator machine is inserted in the uterus to remove the contents.
  • A curette (scraping the sides of the uterus) ensures that no tissue remains in the uterus.
77
Q

What are two methods of surgical abortions?

A

Vacuum aspiration
