According to BostonIVF.com:
ADHESIONS – Scar tissue that may be located in the abdominal cavity, fallopian tubes, or inside the uterus. Can interfere with the transport of the egg and implantation of the embryo in the uterus.
AMENORRHEA – Lack of menstrual period for 6 months or more.
ANDROLOGIST – A physician who performs evaluations of male fertility.
ANOVULATION – The failure to ovulate. This is the most common cause of female infertility. There are many different causes for the failure to ovulate, including problems with the central nervous system or pituitary gland, and abnormalities within the follicles or ovaries.
ASSISTED HATCHING (AH or AZH) – A micromanipulation procedure in which an opening is made into the hard outer surface of the early embryo with the use of chemicals, mechanical techniques, or lasers to improve implantation after the embryo is transferred into the uterus.
ASSISTED REPRODUCTIVE TECHNOLOGY (ART) – A group of treatment methods used to improve fertility, which involves collecting the eggs and putting them in direct contact with sperm. Including IVF, GIFT, ZIFT, ICSI, and Assisted Hatching.
AZOOSPERMIA – Semen that contains no sperm, either because the testicles can’t make sperm or because the man’s reproductive tract is blocked.
BASAL BODY TEMPERATURE (BBT) – The body temperature when taken at its lowest point, usually in the morning before getting out of bed. Charting a woman’s BBT is used to document ovulation. If the BBT pattern rises about a half degree during the latter half of the menstrual cycle, it suggests that ovulation has taken place.
BETA hCG TEST (BhCG) – A blood test used to detect very early pregnancies and to evaluate the development of the embryo. The test measures hCG, which is secreted by the placenta after implantation.
BLASTOCYST – A stage of embryonic development that occurs about 5 days after fertilization, when the embryo consists of two different cell types (those that will form the placenta and those that will form the fetus) and a central cavity.
BLASTOCYST TRANSFER – Replacing blastocysts into the uterus.
BLIGHTED OVUM (EGG) – Rarely-used term for an embryo that attaches itself to the uterine wall but the embryo does not develop. The amniotic sac may only contain fluid and no fetal tissue when the miscarriage occurs.
BROMOCRIPTINE (Parlodel, Dostinex) – These fertility drugs are used to reduce the prolactin secreted from the pituitary in those women with high prolactin levels.
CERVICAL MUCUS – The sticky, thick mucus produced by glands in the cervical canal that plugs the opening of the cervix. Most of the time this thick mucus plug prevents sperm and bacteria from entering the womb unless ovulation is about to take place. At this time, under the influence of estrogen, the mucus becomes thin, watery, and stretchy so that sperm can pass into the womb.
CERVIX – The opening into the uterus.
CHEMICAL PREGNANCY – A pregnancy verified by lab tests but which results in an early miscarriage before a gestational sac is seen on an ultrasound.
CHOCOLATE CYST – A cyst in the ovary that is filled with blood. It is known medically as an “endometrioma.” The term chocolate cyst is used because it resembles melted chocolate. A chocolate cyst forms when endometriosis implants invade the ovary and bleed.
CLOMIPHENE (Clomid, Serophene) – Often a first line of treatment to stimulate and induce ovulation. Clomid bindsto estrogen receptors in the hypothalamus. When their sites are occupied, the hypothalamus responds by telling the pituitary to release more FSH.
CONCEPTION – The fertilization of an egg by sperm that leads to the creation of a baby.
CONGENITAL – Conditions present from birth, either hereditary or environmental.
CORPUS LUTEUM – A yellow-colored cyst that forms from the ovarian follicle after it releases an egg. Once formed, the cyst produces estrogen and progesterone to prepare and support the uterine lining for implantation.
CRYOPRESERVATION – The process of freezing tissues or cells and then storing them in liquid nitrogen at very low temperatures. This process is used to store sperm, embryos, and unfertilized eggs. They are stored in small vials or straws that can last for decades.
DONOR INSEMINATION (DI) – A type of artificial insemination using sperm not from the male partner or husband.
DONOR SPERM – Semen specimens donated and used in an ART procedure.
ECTOPIC PREGNANCY – Also called a tubal pregnancy, this is a condition in which the embryo implants outside of the uterus, usually in the fallopian tube, although it can also occur in the ovary or abdominal cavity. If such a pregnancy is allowed to continue, it may eventually rupture the fallopian tube and cause life-threatening hemorrhage. Such a pregnancy can never be sustained and often leads to decreased or complete loss of function in the affected tube.
EGG DONATION – Process in which eggs from a fertile woman are donated to an infertile woman for use in an ART procedure.
EGG RETRIEVAL – A procedure used to collect eggs from a woman’s follicles for use in IVF, usually performed with ultrasound-directed needle aspiration during IVF.
EMBRYO – A term that describes the time from fertilization of the egg until the first few weeks of pregnancy.

ENDOMETRIAL BIOPSY – A removal of a small piece of the uterine lining for microscopic study.
ENDOMETRIOSIS – A chronic condition in which some of the normal cells that line the internal cavity (endometrial tissue) are found outside the uterus – most often in the pelvic area involving the ovaries. Endometriosis may interfere with ovulation and with the implantation of the embryo.
EPIDIDYMIS – A coiled, tubular organ attached to and lying on the testicle that stores the sperm before ejaculation.
ESTRADIOL – A natural estrogen produced by the ovary and released through reproductive life. It supports the development of the uterine lining and is important to breast and other female organ development.

FIBROID/MYOMA – Benign tumors of the uterine muscle and connective tissue.
FIMBRIA – Fingerlike projections at the end of the fallopian tube nearest the ovary. When stimulated by the fluid released from the follicles during ovulation, the fingerlike ends grasp the egg and sweep it into the tube
FOLLICLE STIMULATING HORMONE (FSH) – A reproductive hormone that stimulates sperm production in a man; in a woman, FSH stimulates the growth of the ovarian follicle and the production of eggs.
FOLLICULAR PHASE – The portion of a woman’s cycle before ovulation during which a follicle grows and high levels of estrogen cause the lining of the uterus to grow.

HYSTEROSCOPY – A surgical procedure to check for abnormalities within the uterus. It is performed by placing a small, thin telescope-like instrument through the cervical canal to inspect the inside of the uterus. The procedure can be used both to diagnose and treat problems, since minor surgical repairs also can be done during operative hysteroscopy.

INTRACYTOPLASMIC SPERM INJECTION (ICSI) – A lab procedure in which a single sperm is injected through the outer shell of the egg to enable fertilization.
INTRAUTERINE INSEMINATION (IUI) – An Assisted Reproduction Technique which deposits washed sperm directly into the uterus, bypassing the cervix, and allowing the sperm to enter the fallopian tubes (where fertilization normally occurs).

STERILITY – A condition that results in the absolute inability to reproduce.
SWIM-UP TEST – A useful diagnostic procedure that also can be used to remove sperm from semen. It has some advantages to sperm washing because the live sperm will swim up to the culture media leaving behind most of the debris.
TESTICLES – Also known as testes, testicles are the male sex glands located in the scrotum. Testicles store and produce sperm and are the main source for the secretion of the male hormone testosterone.
TESTICULAR BIOPSY – A surgical procedure in which a small sample of testicular tissue is removed for microscopic examination to see if sperm are present and able to be retrieved.
TESTOSTERONE – The primary male hormone responsible for secondary sex characteristics and for supporting the sex drive. Testosterone is also necessary for sperm production.
TUBAL LIGATION – Female sterilization. The fallopian tubes are blocked to prevent the egg from meeting sperm. Commonly known as “having the tubes tied”.
ULTRASOUND – Use of high-frequency sound waves that are reflected off solid tissues to give an image of internal body structures. This device is used to detect and count follicle growth in many fertility treatments and to detect and monitor pregnancy.
