Trying to Conceive Terms and Acronyms

HSG -- Hysterosalpingogram - x-ray The hysterosalpingogram is an x-ray test that is helpful in determining the cause of infertility. A picture is taken after dye has filled the inside of the uterus and fallopian tubes, revealing any abnormalities of the uterus as well as tubal problems such as blockage and dilation. It has been claimed that pregnancy rates are increased in a cycle when an HSG has been performed. Using catheters, a radiologist can open tubes that are proximally blocked.

HPT -- Home Pregnancy Test Pregnancy tests detect the hormone your body makes during pregnancy: hCG (human chorionic gonadotropin) in urine. The amount of pregnancy hormone increases as pregnancy progresses.

ICSI -- Microfertilization ICSI is an acronym for intracytoplasmic sperm injection which means injecting sperm into the cytoplasm of the egg. ICSI is used in cases of male infertility (low sperm count, damaged or missing vas deferens, had an irreversible vasectomy) as well as various other situations such as low egg retrieval.

ISA -- Independent Surrogacy Arrangement There are two ways to find a potential match to work with during a surrogacy through a surrogacy agency or finding a match independently. An independent surrogacy arrangement has several benefits -- the matching is free, you can choose traditional surrogate, the surrogate doesn't have to meet as strict guidelines, fees can be negotiated, etc.

Implantation When the fertilized egg (blastocyst) settles into the thick uterine lining (endometrium). This occurs approximately 6-10 days after conception.

IUI -- Intrauterine Insemination IUI is a fertility treatment that uses a catheter to place washed sperm directly into the uterus. The goal of IUI is to increase the number of sperm that reach the fallopian tubes and increase the chance of fertilization.

IVF -- In-Vitro Fertilization In Vitro Fertilization is the process of fertilization by manually combining an egg and sperm in a laboratory dish. When the IVF procedure is successful, a procedure known as embryo transfer is used to physically place the embryo in the uterus.

LH -- Luteinizing Hormone A female hormone secreted by the pituitary gland, necessary to regulate ovarian function.

LP -- Luteal Phase The luteal phase of the menstrual cycle spans the time between ovulation and the onset of the next menses. A luteal phase is usually 12 - 16 days and should be at least 10 days for successful implantation. A short luteal phase can make it difficult for a women to get pregnant.

Menstruation/Menstrual Cycle The monthly cycle of changes in the ovaries and the lining of the uterus (endometrium), starting with the preparation of an egg for fertilization. When the follicle of the prepared egg in the ovary breaks, it is released for fertilization and ovulation occurs. Unless pregnancy occurs, the cycle ends with the shedding of part of the endometrium, which is menstruation. Although it is actually the end of the physical cycle, the first day of menstrual bleeding is designated as "day 1" of the menstrual cycle in medical parlance.
