Gestational diabetes. Elevated blood sugar levels in the mother while she is pregnant. During pregnancy, the placenta normally produces hormones that antagonize insulin.
Gestational sac amniotic sac. The fluid-filled sac surrounding an embryo that develops within the uterine cavity. Ultrasound can detect the sac in the uterus at a very early stage of pregnancy. FSH and LH may be purified or synthetically produced to be used as ovulatory drugs. Substances secreted from organs of the body, such as the pituitary gland, adrenal gland, or ovaries, which are carried by a bodily fluid such as blood to other organs or tissues where the substances exert a specific action.
Infertility is the result of a disease of the male or female reproductive tract that prevents the conception of a child or the ability to carry a pregnancy to delivery. The duration of unprotected intercourse with failure to conceive should be about 12 months or more before an investigation is undertaken, unless medical history, age, and physical findings dictate earlier evaluation and treatment.
In vitro fertilization IVF. A method of assisted reproduction that involves combining an egg with sperm in a laboratory dish.
IVF is generally performed in conjunction with medications that stimulate the ovaries to produce multiple eggs in order to increase the chances of successful fertilization and implantation. IVF bypasses the fallopian tubes and is often the treatment choice for women who have badly damaged or absent tubes. The naturally occurring expulsion of a nonviable fetus and placenta from the uterus; also known as spontaneous abortion or pregnancy loss. Mono - one; zygotic - fertilized egg.
One egg fertilized by a single sperm that divides into two embryos. Identical twins. Multifetal pregnancy reduction. Also known as selective reduction. A procedure to reduce the number of fetuses in the uterus. As the risk of miscarriage spontaneous abortion and other problems increases with the number of fetuses present, this procedure may be performed in an attempt to prevent the entire pregnancy from aborting or delivering very prematurely.
Ovulation induction. The administration of hormone medications ovulation drugs that stimulate the ovaries to develop a follicle and ovulate. A disk-shaped vascular organ attached to the wall of the uterus and to the fetus by the umbilical cord. It provides nourishment to the fetus and carries away waste.
A disorder occurring during pregnancy that affects both the mother and the fetus. Preeclampsia is characterized by high blood pressure, swelling, and protein found in the urine.
This disorder, also know as toxemia, can restrict the flow of blood to the placenta. Respiratory distress syndrome RDS. A lung disease that affects premature infants and causes increasing difficulty in breathing. The sperm head carries genetic material chromosomes ; the midpiece produces energy for movement; and the long, thin tail wiggles to propel the sperm.
The administration of fertility medications in a manner intended to achieve development and ovulation of multiple ovarian follicles. Superovulation is often combined with intrauterine insemination as an infertility treatment. Thread used to close an incision made during surgery. It generally is absorbable or self-dissolving. Tocolytic agents. Medications that may slow or stop premature labor.
Also called sonogram. A picture of internal organs produced by high frequency sound waves viewed as an image on a video screen; used to monitor growth of ovarian follicles, to retrieve eggs, and to monitor a fetus or pregnancy. Ultrasound examinations can be performed either abdominally or vaginally. Uterus womb. The hollow, muscular organ in the pelvis where an embryo implants and grows during pregnancy.
The lining of the uterus, called the endometrium, produces the monthly menstrual blood flow when there is no pregnancy. No portion herein may be reproduced in any form without written permission.

Risk Factors for Multiple Pregnancy Naturally, twins occur in about one in pregnancies, triplets in about one in 10, pregnancies, and quadruplets in about one in , pregnancies.
Preterm Birth Preterm labor and birth pose the greatest risk to a multiple pregnancy. Placental Problems The placenta is attached to the wall of the uterus, and the fetus is attached to the placenta by the umbilical cord. Preeclampsia Preeclampsia, also known as toxemia, occurs 2 to 5 times more often in multiple pregnancies.
Diabetes Women with multiple pregnancies are more likely to develop gestational diabetes during pregnancy. Multifetal Pregnancy Reduction When a triplet or high-order multiple pregnancy occurs, multifetal pregnancy reduction may be considered to improve the chance for survival of the fetuses. Metabolic and Nutritional Considerations There is an increased need for maternal nutrition in multiple pregnancies. Activity Precautions Many physicians who manage multiple pregnancies believe that a reduction in activities and increased rest prolongs these pregnancies and improves outcomes.
Monitoring a Multiple Pregnancy Since preterm birth and growth disturbances are the major contributors to newborn death and disability in multiples, frequent obstetric visits and close monitoring of the pregnancy are needed. Ideally, in the operating room there should be one pediatrician and one nurse for each baby. Depending on the individual needs of each newborn, the mom and dad may be able to hold or touch their babies. But some babies are very premature and are immediately attached to many wires, tubes, and machines and taken to the NICU neonatal intensive care unit with very little interaction with mom and dad.
All newborns should be footprinted and have identification bands attached before leaving the operating room. A cesarean section delivery is major abdominal surgery, done in a sterile operating room. Usually one support person is allowed to be present. The average weight of a triplet is grams 3 pounds, 12 ounces , which is half the weight of the average single newborn grams, 7 pounds, 6ounces. More than a third of triplets weigh less than grams 3 pounds, 3 ounces at birth.
Less than grams is called very low birth weight. Being very low birth weight places these tiny babies at much greater risk of long-term disabilities and of death in the first year of life, compared to a single newborn. These deaths are usually the result of prematurity, low birth weight, respiratory distress syndrome severe breathing problems , birth defects , and SIDS sudden infant death syndrome.
Although triplets are a triple blessing, carrying three babies where there is usually one will be very difficult for your body. But, we can also divide beats into three equal parts and we do this using a triplet. This allows us to play rhythms that would otherwise not be possible to notate or at least would be very complicated.
This just is showing which notes are in the triplet. Remember to be a triplet it needs to have a number three above or below the notes. In other words, if all the notes in a triplet are the same we take two of the notes and add their values together to get the answer.
