Done as part of an IVF treatment, ICSI involves injecting a single sperm into an egg. Ovarian Transplantation in a Series of Monozygotic Twins Discordant for Ovarian Failure. (PDF, 188 KB) The New England Journal of Medicine, 2007. Contents Definition[edit] "Demographers tend to define infertility as childlessness in a population of women of reproductive age," whereas "the epidemiological definition refers to "trying for" or "time to" a pregnancy, generally in a population of women exposed to" a probability of conception.[8] Currently, female fertility normally peaks at age 24 and diminishes after 30, with pregnancy occurring rarely after age 50.[9] A female is most fertile within 24 hours of ovulation.[9] Male fertility peaks usually at age 25 and declines after age 40.[9] The time needed to pass (during which the couple tries to conceive) for that couple to be diagnosed with infertility differs between different jurisdictions. Hyperprolactinemia: If prolactin levels are high, and the woman is not pregnant or breastfeeding, it may affect ovulation and fertility. Surgical Management of Male Infertility. (PDF, 2 MB) Chapter 12 from textbook, Male Infertility, 1992.

Overweight or obesity: This may reduce the chance of conceiving. PID leads to a blockage of the fallopian tubes, which prevents fertilization. Happily, many couples treated for infertility go on to have babies. PPT Presentation Summary : Evaluation of Fertility: A Cornerstone to Improved Reproductive Health for Women Overview.

It does not induce ovulation, but reduces the production of prolactin by the pituitary.[20] Bromocriptine is only prescribed in cases of overproduction of prolactin (hyperprolactinemia). However, intercourse 3 times a week results in a probability of conception around 50% within 6 months. Prolactinoma A prolactin-secreting adenoma is the most common functional pituitary tumor.

8) Unexplained/other: Sometimes a full evaluation does not reveal the cause of infertility. The four types of third party reproduction are 1) sperm donation – a process by which donated sperm is used for insemination in the uterus, or for fertilization of eggs in the IVF process; 2) egg or ovum donation – a process by which an egg donor undergoes an IVF cycle in order to obtain her eggs which are then donated and fertilized. The epididymis is a coil-like structure in the testicles which helps store and transport sperm. These include: non-steroidal anti-inflammatory drugs (NSAIDs) – long-term use or a high dosage of NSAIDs, such as ibuprofen or aspirin, can make it more difficult to conceive chemotherapy – medicines used for chemotherapy can sometimes cause ovarian failure, which means your ovaries will no longer be able to function properly neuroleptic medicines – antipsychotic medicines often used to treat psychosis; they can sometimes cause missed periods or infertility spironolactone – a type of medicine used to treat fluid retention (oedema); fertility should recover around 2 months after you stop taking spironolactone Illegal drugs, such as marijuana and cocaine, can seriously affect fertility and make ovulation more difficult. The ICSI process takes place following a cycle during which fertility drugs are administered to the female partner to aid in the production of multiple eggs.

Chronic conditions: These include AIDS or cancer. A typical adverse effect can be ovarian hyperstimulation. Causes Potential causes of male infertility are: The complete absence of sperm (azoospermia) Low sperm count (oligospermia) Abnormal sperm shape (teratozoospermia) Problems with sperm movement (asthenozoospermia) Sperm that is completely immobile (necrozoospermia); the sperm may be alive and not moving, or they may be dead Problems with sperm delivery, due to sexual dysfunction, an obstruction, previous vasectomy, or retrograde ejaculation Problems with erections or other sexual problems There are a variety of conditions that may lead to male infertility. However, hormones are not the main problem in 97% of infertile men. Ovulation disorders appear to be the most common cause of infertility in women. In most cases however, sperm function may not improve and therefore any attempts at pregnancy may require additional treatments or procedures performed by our clinic. Radiation therapy: If this is aimed near the reproductive organs, it can increase the risk of fertility problems. It causes a blood stasis that raises the temperature of the scrotum. 24 Other tests of ovarian reserve, such as the clomiphene (Clomid) challenge test, antral follicle count, and antimüllerian hormone level, are also generally performed to predict response to ovarian stimulation with exogenous gonadotropins and assisted reproductive technology. Peritubaric adhesions can be caused by endometriosis. In some cases, the cause of infertility or subfertility could not be suspected from the history taking and clinical examination.
