8,45 Figure 1 provides an algorithmic approach to the evaluation of infertility.   Enlarge      Print Infertility Evaluation Figure 1. Additionally, the sperm may be unable to cross the cervical mucus or may have ultrastructural abnormalities. Lack of ovulation Patients with anovulation who did not ovulate after several cycles of CC at different doses of treatment are deemed clomiphene resistant. The main approach to correcting or removing these uterine abnormalities is by hysteroscopy, a surgical method by which a narrow scope with a camera is placed within the uterine cavity.

Men with elevated prolactin levels present with gynecomastia, diminished libido, erectile dysfunction, and occasionally galactorrhea. This combination of laboratory test results may indicate ovarian insufficiency or diminished ovarian reserve. The avascular nature of the septum is theorized to interfere with implantation and maintenance of the embryo. It is an approach to disseminate the recommended medical care of infertile couple to the practicing clinicians. The acrosome should be 40-70% of the size of the head, and no mid piece or tail abnormalities should be present. ED may be the consequence of the conversion of androgens to estradiol.

Women who experience very heavy, painful periods may be showing signs of endometriosis, a condition where tissues usually found in the womb are present elsewhere in the body. Antibodies that attack sperm Anti-sperm antibodies are immune system cells that mistakenly identify sperm as harmful invaders and attempt to eliminate them. Prescription drugs can be useful when treating infertility issues.

For conception to take place, several events should happen correctly and at exactly the right time. Showell MG, Brown J, Yazdani A, Stankiewicz MT, Hart RJ.

Intracytoplasmic sperm injection[edit] ICSI technique is used in case of poor semen quality, low sperm count or failed fertilization attempts during prior IVF cycles. In addition, if a man’s sperm do not move correctly, they may not be able to meet with and fertilize an egg. Ideally, patients respond to replacement with exogenous GnRH or HCG, an LH analogue, although this does not always occur. Treatment of the cause: Male Factor: (Liaise with the andrologist) 1. In vitro fertilization[edit] IVF is the most commonly used ART. Studies show that the IUI is most successful when it is coupled with fertility drugs to enhance ovulation, with success rates between 5% and 20% per cycle. Heterologous or therapeutic insemination, formerly called artificial insemination by donor sperm, refers to the use of frozen sperm that has been quarantined for at least 6 months. [108] Thereafter, the specimen is ready to use once the donor has undergone the necessary screening tests required by the tissue bank, the US Food and Drug Administration (FDA), and the American Society for Reproductive Medicine (ASRM). [111] The source of the sperm can be either anonymous or from a donor designated by the couple. In 1985, he constructed the pelvi-trainer = laparo-trainer, a practical surgical model whereby colleagues could practice laparoscopic techniques. Release of GnRH is stimulated by melatonin from the pineal gland and inhibited by testosterone, inhibin, corticotropin-releasing hormone, opiates, illness, and stress. 47 Motivational interviewing techniques for modifiable risk factors, such as obesity, tobacco, illicit drugs, and alcohol, can decrease the targeted risk factor. Endometrial biopsy should be performed only in women with suspected pathology (chronic endometritis or neoplasia). If an endocrinopathy, such as hyperprolactinemia, is diagnosed, the underlying cause should be treated.
