  • TOLAC: Trial of Labor After Cesarean. An attempt to have a vaginal birth after a cesarean section in a previous pregnancy.
  • GBS: Group B Strep. A type of bacterial infection that can be found in a pregnant woman’s vagina or rectum. Women are typically tested for GBS late in pregnancy because it can be harmful to the baby during delivery.

  • PGT: Preimplantation Genetic Testing. A procedure used to identify genetic defects in embryos created through IVF before pregnancy.
  • MC: Miscarriage. The loss of a pregnancy before the fetus is viable outside the womb, typically defined as before 20 weeks of gestation.
  • PCOS: Polycystic Ovary Syndrome. A hormonal disorder causing enlarged ovaries with small cysts on the outer edges, often leading to infertility issues.
  • RPL: Recurrent Pregnancy Loss. The occurrence of three or more consecutive pregnancy losses before 20 weeks of gestation.
  • ZIFT (Zygote Intrafallopian Transfer): A fertility treatment where a fertilized egg is placed into the fallopian tube rather than the uterus.
  • HSG (Hysterosalpingography): An X-ray test that looks at the inside of the uterus and fallopian tubes and the area around them, often used to investigate blockages that could affect fertility.
  • D&C (Dilation and Curettage): A surgical procedure often performed after a miscarriage or for diagnostic purposes. During a D&C, the cervix is dilated, and a special instrument is used to scrape the uterine lining to remove tissue.

helpful and informative terminology (Pregnancy related)

These terms cover aspects of medical diagnoses, treatment procedures, tests, and emotional experiences related to pregnancy, childbirth, postpartum period and infertility. Here’s a list of key terms and their definitions:

  • Kick Count: A method used by expectant mothers to monitor their baby’s activity levels by counting the number of kicks or movements felt within a certain time period, often recommended in the third trimester.
  • Braxton Hicks Contractions: Often referred to as “practice contractions,” these are irregular, usually painless contractions that occur throughout pregnancy. They are not a sign of labor.
  • Amniocentesis: A medical procedure used in prenatal diagnosis, where a small amount of amniotic fluid is sampled from the amniotic sac surrounding a developing fetus. It can provide information about the baby’s health.
  • Epidural: A form of anesthesia used during labor to reduce pain in the lower part of the body.
  • Linea Nigra: A dark vertical line that appears on the abdomen during pregnancy due to hormonal changes.
  • Mucus Plug: A plug of mucus that blocks the cervical canal during pregnancy, providing protection against infection. It is often expelled just before or during labor.
  • Nesting: An urge to clean and organize one’s home before the arrival of the baby, often seen as an instinctual behavior that signals the approach of labor.
  • Surfactant: A substance that helps keep the air sacs in the lungs from sticking together. It is particularly important for premature babies, as their lungs may not have produced enough surfactant yet.
  • Preeclampsia: A pregnancy complication characterized by high blood pressure and signs of damage to another organ system, most often the liver and kidneys.
  • Skin to Skin: A practice where a baby is dried and laid directly on the mother’s bare chest after birth, which can help regulate the baby’s temperature and heart rate, encourage bonding, and initiate breastfeeding
  • Infertility: The inability to conceive after one year of regular, unprotected sexual intercourse, or the inability to carry a pregnancy to term.
  • Reserve: The capacity of the ovary to provide egg cells that are capable of fertilization resulting in a healthy and successful pregnancy.
  • Semen Analysis: A test that evaluates the quantity and quality of a man’s semen and sperm to assess his fertility.
  • Embryo Transfer: The process of placing an embryo into a woman’s uterus or the uterus of a surrogate mother, hoping it will implant and result in a pregnancy.
  • Cryopreservation: The process of freezing eggs, sperm, or embryos for future use.
  • Surrogacy: An arrangement where a woman agrees to carry and deliver a child for another person or couple.
  • Egg Donation: A process where eggs are donated by one woman (the donor) to another (the recipient), typically involving IVF to facilitate the pregnancy.
  • Sperm Donation: A process where sperm are donated by a man (the donor) to assist an individual or couple in achieving pregnancy.
  • Secondary Infertility: The inability to become pregnant or to carry a pregnancy to term after previously giving birth to a child or children.
  • Endometriosis: A condition in which tissue similar to the lining inside the uterus is found outside the uterus, causing pain and potentially affecting fertility.
  • Tubal Factor Infertility: Infertility resulting from damage or blockage of the fallopian tubes, which prevents the egg from being fertilized or the fertilized egg from reaching the uterus.
  • Sperm Motility: The ability of sperm to move efficiently. This is important for fertility because sperm need to navigate through the female reproductive tract to reach and fertilize an egg.
  • Sperm Morphology: The shape and structure of sperm. Abnormal morphology may impair the ability of sperm to fertilize an egg.
  • Blastocyst: A stage of embryo development, typically reached five to six days after fertilization, when the embryo has divided many times and is ready for implantation in the uterine lining.
  • Egg Retrieval: A procedure in IVF where eggs are collected from the ovaries with a needle guided by ultrasound.
  • Assisted Hatching: A laboratory technique used in IVF where the outer shell of the embryo (the zona pellucida) is thinned or breached to assist the embryo in breaking out (hatching) and implanting in the lining of the uterus.
  • Male Factor Infertility: Infertility due to low sperm count, poor sperm motility, or abnormal sperm morphology.
  • Ovulation Induction: The use of medications to stimulate ovulation in women who do not ovulate regularly or at all.
  • Sperm Analysis: A test to measure the quantity and quality of a man’s sperm.
  • Zygote: The cell formed by the combination of a sperm and an egg at fertilization.
  • Ectopic Pregnancy: A pregnancy in which the embryo implants outside the uterus, most commonly in the fallopian tubes. It’s a serious condition that can cause significant health risks to the mother.
  • Luteal Phase: The phase of the menstrual cycle that begins after ovulation and ends with the start of menstruation. It’s when the body prepares for a possible pregnancy, and a key focus in infertility discussions for its length and hormonal environment being crucial for implantation and early pregnancy maintenance.

These terms represent just a portion of the extensive vocabulary associated with TTC. Understanding these terms can help individuals and couples navigate their fertility journey more effectively.
