Q

Key points in fertilization and implantation

A

Ovulation, Fertilization occurs 12-24 hours after ovulation
~You can get pregnant in larger window than 12-24 hours bc sperm lives longer (48 hours to 8 days)

Sperm follow the chemical signal of the egg
~Around one teaspoon of ejaculate is released (200 million-400 million sperm in teaspoon)
~Sperm swim 1-3 cm per hour
~Egg secretes chemical that attracts sperm

54
Beginning of labor
Mucous plug discharge: small amount of bloody mucus (plug in the cervix that prevents germs from passing from vagina into uterus is shed) Ruptured membranes (water breaking): usually occurs later in labor and not as the first step Increased Braxton-Hicks contractions
55
First stage of labor
Effacement of cervix: thinning of cervix ~Regular contractions of uterus cause cervix to thin out and dilate Dilation of cervix ~Must dilate to 10 cm/4 inches before baby can be born ~Can take variety of time (2 hours-24 hours or more) ~~Average is about 12-15 hours for first pregnancy, then 8 hours or less for future pregnancies Contractions ~Uterine contractions becomes closer and closer in time and more intense ~When contractions are 4-5 mins apart you are ready to go to hospital
56
Second stage of labor
Babies head moves to birth canal Urge to push Labor lasts a few mins to a few hours ~Usually much shorter than first stage The uterus contracts down, pushing baby to birth canal Crowning: top of head is visible Episiotomy:incision is made to perineum to make larger entrance for babies to exit ~17% of women ~more recommended for tissues to naturally tear for better healing
57
2nd stage of labor: Baby has first birth
Still connected by umbilical cord Air in lungs When baby can breathe on its own, umbilical cord is cut Once baby is born, immediately place on mothers chest to promote parent-infant bonding Promotes breast-feeding
58
Third stage labor
Placenta detaches Afterbirth expelled Any other fluids secreted If episiotomy occur, stitches are given
59
Cesarean section (C-section)
C-section surgical procedure used for delivery ~Baby's head too large ~Persons pelvis is too small ~Baby is breech or transverse(meaning feet first) ~Cervix is not dilating ~Person is nearing exhaustion ~Placenta previa: Placenta is attached to uterus and too close to cervix
60

About 31.7% of births in canada in 2022 (higher than other western countries)
61
Vaginal birth is the most safest way Rates of c-section are increasing bc More fetal monitoring during labor (more able to see if baby is in distress)

Certain risks higher after c-section
Infection of bladder or uterus Injury to uterus Injury to baby
63
C-section rates can be reduced when
hospital adopt appropriate precautions
64
