Clinical Treatment of Infertility: A Practicable Algorithm
Understanding and assessing the cost of medical coverage for the treatment of infertility has long been a difficult task for pharmaceutical benefit and HMO managers. A new comprehensive algorithm now offers an accurate measurement of costs for this treatment for any employee population and for the entire range of treatment options. This tool will allow pharmaceutical benefit and HMO managers to assess these costs as a component of an overall health benefit, while also providing insights into the best treatment paths for covered patients.

Examining PTSD as a Complication of Infertility
Posttraumatic stress disorder (PTSD) is a psychiatric disorder that may develop following exposure to threatened or actual injury or death. While commonly associated with war or natural disaster, symptoms of PTSD have been described in patients who are undergoing or who have completed infertility treatment or high-risk pregnancies.

Polycystic Ovary Syndrome

Polycystic Ovary Syndrome (PCOS)

Polycystic ovarian syndrome (PCOS) was originally described in 1905 by Stein and Leventhal as a syndrome consisting of amenorrhea, hirsutism, and obesity in association with enlarged polycystic ovaries. It is now realized that this relatively common syndrome is an extremely heterogenous clinical syndrome that begins soon after menarche and some authors prefer to refer to it as a syndrome of hyperandrogenic chronic anovulation.

Hirsutism

Facial Hair on a Woman: Diagnosing and Treating a Pathological Twist on a Common Problem

Doctors Must Recognize 'Broader Picture' in Assessing Hirsutism

Although hirsutism is common among women, the disorder is traditionally underreported, and patients who seek treatment often do so for psychosocial reasons. Physicians, though, should recognize that the condition--androgen-stimulated excessive hair growth--may signal potentially serious metabolic disorders, experts said.

From: Medical Tribune: Obstetrician & Gynecologist Edition

 

Hirsutism and Virilization

Hirsutism is defined as excessive hair growth in women in androgen-sensitive areas of the body, such as the face, chest, around the nipples, lower back and buttocks, inner thighs, and genitalia. Hirsutism is usually a benign condition and is not accompanied by other signs of virilization.

 

Evaluation of Women With Hirsutism

Hirsutism is a common disorder of androgen activity that manifests in women as excessive growth of terminal hairs in androgen-dependent regions of the body. In most women with hirsutism, the condition is idiopathic or caused by polycystic ovary syndrome. However, a thorough evaluation is necessary to exclude more serious causes of hirsutism

 

Female Infertility

Infertility in Women: The Causes and Treatments

Infertility is defined as the inability to conceive after sexual intercourse for at least one year without contraception.  Infertility affects approximately 10-15% of all couples in the United States.  Nearly 40-50% of infertility is attributed to the females.  The first part of this paper will attempt to describe the various causes of infertility in women.  The second part will attempt to offer many of the possible types of treatment to cure infertility in women

TSEICSI - The End Of Male Infertility?

Now it is possible to actually extract sperm from the testis of these patients, and inject them into their wife's eggs. This is called TSEICSI (pronounced "sexy") - Testicular Sperm Extraction with IntraCytoplasmic Sperm Injection.

 

Concerns and Recommendations for ICSI Treatment

"Intracytoplasmic sperm injection (ICSI) has developed as a radical form of micro-assisted fertilization [Fishel, et al., 1993; Van Steirteghem, et al., 1993]. It is a remarkably effective procedure to assist fertilization for men with severe infertility [Van Steirteghem, et al., 1994]. However, it bypasses all natural sperm selection processes that have evolved to regulate vertebrate fertilization, and the long-term implications for the life expectancy and fertility of the children are unknown."

Assisted Reproductive Technologies

SART Statistics

These tables are summary statistics from the annual SART (Society of Assisted Reproductive Technologies) reports that are published yearly in Fertility and Sterility. These reports of assisted reproductive technologies are prepared by SART and the American Society for Reproductive Medicine. They represent voluntary reporting by programs registered with SART.

 
Embryo Cryopreservation

In 1978, the first child from the advanced assisted reproductive technology of in vitro fertilization was born. Five years later, identical twins were born after transfer of an embryo that had previously been frozen and thawed. In 1988, a pregnancy was reported from an egg that had undergone assisted fertilization by placing spermatozoa directly into the perivitelline space using micromanipulation. The very rapid progress of assisted reproductive technologies in humans was possible because of the immense foundation of basic research on the events surrounding fertilization and early development. These studies have been in progress for decades.

 

Assisted Hatching

Assisted hatching (AH) may help with embryo implantation. Embryo implantation is one of the greatest barriers to success in In Vitro Fertilization (IVF) cycles.

 
Epidural Anesthesia in an In Vitro Fertilization and Embryo Transfer Program

Objective: To investigate the potential advantages of epidural anesthesia in an in vitro fertilization and embryo transfer program.

 

Micromanipulation

These new IVF techniques have significantly improved chances for a successful pregnancy in many In Vitro Fertilization (IVF) patients. Micromanipulation is useful for patients whose partners have severe male factor infertility.

 
Sperm and Oocyte Conditioning Prerequisites for Successful IVF/ET

Of paramount importance in a program of in vitro fertilization (IVF) is a deliberate attempt to simulate, as closely as possible, the events that occur naturally in oocyte maturation and fertilization.
