IVF/ICSI 38. Controlled ovarian stimulation: - By urinary or recombinant FSH and/or HMG. - Dose depends on age, BMI, presence of PCO and ovarian reserve. - Monitoring of folliculometry by USS and E2. Triggering of ovulation: - By urinary of recombinant HCG, 36 before oocyte retrieval. However, it could be the future for the treatment of multiple diseases, including infertility.

The vast majority of anovulation patients belong to the WHO2 group and demonstrate very heterogeneous symptoms ranging from anovulation, obesity, biochemical or clinical hyperandrogenism and insulin resistance.[14] Treatments[edit] Anovulation can potentially be reversed by lifestyle changes.[15] Lifestyle changes[edit] In women with polycystic ovary syndrome with anovulation, weight loss generally results in improved menstrual regularity, ovulation, and pregnancy rates.[16] In otherwise healthy women with anovulation, avulatory disorders may be favorably influenced by a healthy diet such as a higher consumption of monounsaturated fats rather than trans fats, vegetable rather than animal protein sources, high fat dairy, multivitamins, and iron from plants and supplements.[15] Ovulation induction[edit] The main alternatives for ovulation induction medications are: Antiestrogen, causing an inhibition of the negative feedback of estrogen on the pituitary gland, resulting in an increase in secretion of follicle-stimulating hormone. According to Ross, “anything that improves quality of health, like adequate sleep and nutrition,” should improve fertility. Overweight or obesity: This may reduce the chance of conceiving.

The pulsatile nature of GnRH is essential to normal gonadotropin release; a continuous stimulation inhibits their secretion. Laparoscopy for Cryptorchidism. (PDF, 1 MB) The Journal of Urology, 1980. Several days later, embryos -- or fertilized eggs -- get put back into your uterus with a device called an intrauterine insemination catheter. Damaged Sperm Ducts: Seven percent of infertile men cannot transport sperm from their testicles to out of their penis.  This pathway may be blocked by a number of conditions: · A genetic or developmental mistake may block or cause the absence of one or both tubes (which   transport the sperm from the testes to the penis). · Scarring from tuberculosis or some STDs may block the epididymis or tubes. · An elective or accidental vasectomy may interrupt tube continuity. Reproductive Biology. (PDF, 147 KB) The Scientist, 1996. The epididymis is a 3- to 4-cm long structure with a tubular length of 4-5 m. Affected individuals displayed more severe forms of infertility such as azoospermia and severe oligozoospermia.[27] Other causes[edit] Factors that can cause male as well as female infertility are: DNA damage DNA damage reduces fertility in female ovocytes, as caused by smoking,[28] other xenobiotic DNA damaging agents (such as radiation or chemotherapy)[29] or accumulation of the oxidative DNA damage 8-hydroxy-deoxyguanosine[30] DNA damage reduces fertility in male sperm, as caused by oxidative DNA damage,[31] smoking,[28] other xenobiotic DNA damaging agents (such as drugs or chemotherapy)[32] or other DNA damaging agents including reactive oxygen species, fever or high testicular temperature.[33] The damaged DNA related to infertility manifests itself by the increased susceptibility to denaturation inducible by heat or acid [34] or by the presence of double-strand breaks that can be detected by the TUNEL assay.[35] General factors Diabetes mellitus,[36][37] thyroid disorders,[38] undiagnosed and untreated coeliac disease,[39][40][41][42] adrenal disease[43] Hypothalamic-pituitary factors Hyperprolactinemia Hypopituitarism The presence of anti-thyroid antibodies is associated with an increased risk of unexplained subfertility with an odds ratio of 1. 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.
