The uterine lining is the site of embryo implantation, so a healthy lining is essential for pregnancy. The uterine lining is shed each month as menstrual flow, which is blood mixed with tissue and cellular debris. The average lining thickness...
Progesterone is often prescribed after an intrauterine insemination, or IUI, to promote embryo implantation and increase the chances of pregnancy. Progesterone can be given by several routes including oral, vaginal and intramuscular injection....
The first week of an embryo's life is critical to its survival. During this time, the embryo must undergo genetic, metabolic and developmental changes that allow for implantation in the uterine lining. The mother's menses will cease, and...
Fibroids are a benign growth of uterine muscle cells that can impair fertility in three ways. Fibroids may inhibit conception, cause pregnancy loss due to poor placental attachment or may cause pregnancy complications such as pre-term birth,...
Fibroids are overgrowths of tissue in the uterus or womb. They grow from the muscle of the uterine wall and are not cancerous or precancerous. They can extend into the inside (submucosal) or protrude from the outside surface of the uterus...
Progesterone, a steroid hormone, is produced in small amounts by the ovary at the beginning of the menstrual cycle. The level of progesterone at the beginning of the menstrual cycle is usually less than 1.0 ng/ml in most women, MedlinePlus states,...
One of 60 pregnancies is ectopic, or growing outside of the uterus. Vaginal bleeding is common in early pregnancy, occurring in 20 percent to 30 percent of all pregnancies, the American Pregnancy Association says. Vaginal bleeding in ectopic...
Progesterone is an important female hormone; it plays a crucial role in embryo implantation and growth during the secretory phase of the menstrual cycle, which follows ovulation. After ovulation, the leftover remnant of the follicle that contained...
In vitro fertilization (IVF) is the most commonly used form of assisted reproductive technology. During the IVF procedure, a woman's eggs are retrieved during surgery and then fertilized outside of her body with sperm. Several days after...
Few women experience their periods at exactly the same time each month. Although menstrual cycles normally range between 28 and 32 days, according to the American Pregnancy Association (APA), stress, change in routine and illness can affect cycle...
Hormones such as progesterone, produced by the corpus luteum, the leftover "shell" of the follicle that contained the ovulated egg, play a crucial role in maintaining a pregnancy. One sign of inadequate progesterone levels is a short luteal phase,...
Human chorionic gonadotropin (hCG) is an amazing hormone that can signal the wondrous start of pregnancy or warn of the growth of a dangerous tumor. HCG can be detected in either blood or urine. Pharmaceutical preparations of hCG have been misused...
Progesterone is an essential hormone for embryo implantation. Even if you produce a good egg, achieve fertilization and have the egg float down the fallopian tube to arrive at the uterus ready to implant and grow, pregnancy will fail without...
In vitro fertilization, or IVF, is a fertility treatment for women who cannot become pregnant without medical intervention. A number of factors, including male or female infertility or a combination of both can cause couples to turn to IVF. During...
Progesterone suppositories contain the hormone progesterone and work by altering the lining of the uterus. They are available by prescription and are typically used as part of an assisted reproductive technology program, according to Drugs.com....
Uterine fibroids, also called leiomyomata, are benign growths that begin in the smooth muscle (myometrium) of the uterus. Fibroids can grow into the inner cavity of the uterus (submucosal), into the muscular wall (intramural), or into the outside...
Pregnancy and fertility rely on a number of factors, including the health and hormone profiles of the man and woman, correct timing for ovum fertilization and, proper embryo implantation and development. When you are trying to get pregnant, you...
Progesterone is one of the hormones essential for female reproduction. Progesterone, produced by the corpus luteum, the remaining remnant of the follicle that once contained the developing egg, helps maintain a pregnancy, should one occur. When...
The time honored method for your doctor to assign a due date is to take the first day of your last menstrual period, or LMP, count back three months and add seven days. For example, if the first day of your last menstrual period was April 1, count...
Many women undergoing an intrauterine insemination, or IUI, wonder whether exercising after the procedure could affect their ability to conceive. The answer is not straightforward. While there is no definitive evidence that exercise will hinder...

Assisted reproductive technologies (ART) helps couples overcome infertility challenges. However, assisted reproductive technologies do not overcome every barrier. According to data collected by the Centers for Disease Control (CDC), women under...
Secondary infertility is the medical term for having fertility troubles after having at least one child without difficulty. With the exception of congenital birth defects or genetic problems, the causes for secondary infertility are the same as...
The menstrual cycle follows a precise pattern governed by the release of different hormones that interact with one another. Progesterone, whose production increases in the second half of the menstrual cycle, plays a pivotal part in preparing the...
The embryonic period begins at implantation, when the fertilized egg attaches itself into the uterine lining, and continues through the first eight weeks of pregnancy. This is when most rapid changes in prenatal development occur. All the major...
Although every pregnancy is different, many pregnancies present with similar symptoms during the first week. As the embryo makes its descent through the fallopian tube and implants in the uterus, hormone levels soar and changes abound in the...
As many as 7 million couples in the U.S., or one out of six, has trouble getting pregnant, according to Shady Grove Fertility. Many turn to herbs as a reasonably inexpensive alternative to infertility treatments. Infertility can occur if one or...
IVF, or in vitro fertilization, is the process of transferring embryos into the uterus. According to the American Pregnancy Association, this often happens when the embryos are at the two to eight cell stage. Immediately following IVF, a woman is...
The hormone progesterone is given to in vitro fertilization (IVF) patients to help create a favorable uterine environment for embryo implantation and on-going pregnancy. Progesterone can be given in several different ways, including as a pill, a...
