 Get 'Em Out Alive
If hind legs don't enter the birth canal, or the calf is in breech position (rump first, legs forward in sitting position), the calf can't be born.
Even if the legs do enter the canal, birth is generally so slow and difficult the calf suffocates when the umbilical cord breaks or pinches off since head and shoulders are still inside the cow.
If the calf is breech (legs not entering the birth canal), the cow is in early labor a long time and may not start straining at all.

 Birth Stages   (Site not responding. Last check: 2007-10-18)
The first, and longest, lasts an average of fourteen hours in a first birth, but less for later births, and involves the violent contractions which move the fetus into the birth canal.
It is sometimes possible to turn the baby before it moves into the birth canal; if not, a caesarean section, or surgical removal, is performed.
In the third (and final) stage of labor, the uterus continues to contract to expel the placenta and the umbilical cord, and the process of birth is complete.

 Vagina
During live birth, provide the route to deliver the fetus from the uterus to its independent life outside the body of the mother.
During birth, the vagina is often referred to as the birth canal.
The hymen—a membrane situated behind the urethral opening—partially covers the vagina in many organisms, including some human females, from birth until it is ruptured by first coitus, or by any number of other activites including medical examinations, injury, certain types of exercise, introduction of a foreign object, etc.

Birth weights are influenced by breed of the sire, bull within a breed, sex of the calf, age of the cow and, to a slight degree, nutrition of the cow.
A general understanding of the birth process is important to proper calving assistance and, therefore, is presented here and summarized in Table 1.
This stage begins when the fetus enters the birth canal and usually occurs while the cow is lying down.

 What to Expect During Labor and Delivery   (Site not responding. Last check: 2007-10-18)
When the widest part of the baby's head has settled into the birth canal, it is said to be engaged, or positioned for the second stage of labor.
As the baby's head continues to move through the birth canal, the stations will be identified as +1, +2, +3, etc., in reference to the baby's progress in centimeters.
Cesarean birth also is a safe alternative when anatomical problems of the uterus or birth canal prevent successful vaginal delivery.

 Episiotomies do not prevent shoulder injury to infants stuck in birth canal
After birth, the incision wound is sewn up, and it usually takes four to six weeks for recovery.
A more common complication is a shoulder injury to the infant as a result of attempts to dislodge the baby from the birth canal.
Their aim was to determine which method used to finish delivery - episiotomy, or physical maneuvering of the infant in the birth canal, or a combination of both - is most effective at reducing the number of shoulder injuries, a condition called brachial plexus palsy.

The model is connected to a nylon-Lycra glove worn by an obstetrician in order to measure the amount of force applied to an infant and the amount of tension the infant experiences in its neck and brachial plexus -- the nerve network for the upper arms and shoulders -- during certain delivery methods.
The researchers tested the McRoberts' maneuever and two variations of the Rubin's maneuver for disloding an infant whose shoulders are stuck in the birth canal.

 Pregnancy Today - Birth Presentations and Delivery
Put simply, "presentation" is the position of the baby's body when progressing down the birth canal and entering the world or, in other words, how a baby presents itself during her entrance into the world.
They include the fetal lie, which is the axis of the baby relative to that of the mother's; the presentation, which indicates what body part is closest to the pelvic outlet; and the flexion attitude, which refers to how the head of the baby is flexed.
A footling position is when one of the feet is extended down toward the birth canal, and double footling is when both feet are extended down so that the first thing into the birth canal is the feet.

 MedlinePlus Medical Encyclopedia: Birth acquired herpes
Birth acquired herpes is an infection with the herpes virus that an infant acquires at the time of birth.
Newborn infants can become infected with herpes virus while in the uterus (intrauterine herpes), during passage through the birth canal (birth acquired herpes, the most common method of infection), or in the period immediately following birth (postpartum).
However, it is possible for a mother with a primary (first-time) herpes infection to transmit the virus to a child during birth.

Women with genital HPV that expresses as warts do need to know that there is definitely a chance that they can give the disease to their babies, and that the babies will get RRP.
At this stage, we have no idea what "susceptible" looks like (there are suspected genetic differences) or how to predict the outcome of a birth through an infected birth canal.
If I were a woman with genital warts and I were pregnant, I would personally elect to go C-section given the real risk of passing the HPV on through a normal birthing.

 Linguistic Concerns: Birth Canal   (Site not responding. Last check: 2007-10-18)
Increasingly in obstetrics the vagina is being referred to as a "birth canal." A member of a birth trauma support group, and advocate of empowered births, raises an important question about reducing women's bodies to male-defined functions: "Is the penis ever referred to as a seed tube?
What concerns me most about this use of the term "birth canal" is that it removes women from the child-birth process.
It is no longer her vagina, it is the clinicalised birth canal.

Multiple births generally present no problems, and twins are delivered in the same manner as single babies, one after another.
you may suspect a multiple birth if the abdomen is still very large after one baby is delivered; there are more strong uterine contractions, and the baby's size is out of proportion to the mother's abdomen.

 On The Fear of Death: Dying in the Birth Canal by John A. Speyrer
ignificant studies of the effects of birth trauma began in the fifties, but even now after many decades, the idea that people have lifelong psychological and physical problems due to a traumatic birth is rejected by the overwhelming majority of obstetricians and psychiatrists.
But there was another symptom of having almost died in the birth canal which had always been in evidence to some extent, but which after almost 25 years of therapy would surface with an almost unbearable amount of emotional suffering – that symptom was hypochondria.
When I experienced a regression to a "dying in the birth canal" feeling, my anxiety and depressive symptoms were temporarily quieted, even though anxiety and depression always eventually returned.

 Least forceful way to deliver a baby whose shoulders are stuck in the birth canal   (Site not responding. Last check: 2007-10-18)
Johns Hopkins researchers, using a novel birthing simulator designed by biomedical engineering faculty, staff and students at the University, have identified what may be the least forceful way to deliver a baby whose shoulders are stuck in the birth canal.
The maternal model - composed of pleather "skin," carpet foam, foam sealer and other components - features a birth canal, a mock uterus connected to a pneumatic pump to simulate the natural pattern of uterine contractions and force from a mother's pushing, and flexible legs that can be moved to rotate the pelvis.
The fetal model consists of a cloth mannequin outfitted with a joystick device, a spring and wooden dowels representing the cervical vertebrae.

WEDNESDAY, Oct. 6 (HealthDayNews) -- Episiotomies -- incisions that widen the vagina during childbirth -- don't reduce the risk of injury to babies when their shoulders are stuck in the birth canal, says a Johns Hopkins University School of Medicine study.
The study authors wrote that, instead of an episiotomy, doctors should physically maneuver the infant to realign the shoulders to fit within the mother's pelvis.
An episiotomy should be done only when doctors need more room to carry out the maneuvers to dislodge a baby stuck in the birth canal, the authors wrote.
