Fertility awareness methods are used to discern when these changes occur by tracking changes in cervical mucus or basal body temperature. 8,26,27 As opposed to laparoscopy or hysteroscopy, hysterosalpingography is a minimally invasive procedure with potentially therapeutic effects and should be considered before more invasive methods of assessing tubal patency. 8 Couples with unexplained infertility may want to consider another year of intercourse before moving to more costly and invasive therapies, such as assisted reproductive technology. Done as part of an IVF treatment, ICSI involves injecting a single sperm into an egg.

4) In Vitro Fertilization (IVF): In vitro means “outside the body.” IVF is a process whereby eggs are collected and then fertilized by sperm outside the body, in an embryology laboratory. It has been suggested that infertility be classified as a form of disability.[22] Causes[edit] Immune infertility[edit] Antisperm antibodies (ASA) have been considered as infertility cause in around 10–30% of infertile couples.[23] In both men and women, ASA production are directed against surface antigens on sperm, which can interfere with sperm motility and transport through the female reproductive tract, inhibiting capacitation and acrosome reaction, impaired fertilization, influence on the implantation process, and impaired growth and development of the embryo. Afterward, the embryo transfer follows with a sterile special catheter into the cavum uteri.

Sperm are then collected, washed, and added to the eggs in the dish. Estrogen causes negative feedback on the pituitary gland, inhibiting LH and FSH release. Clark AM, Thornley B, Tomlinson L, Galletley C, Norman RJ.

IVF in action Intracytoplasmic sperm injection (ICSI): A single sperm is injected into an egg to achieve fertilization during an IVF procedure. Legal, cultural and religious inquiries have limited the available choices in some countries, such as the use of donor sperms or oocytes.

549 KB Effect of Age on Male Fertility. (PDF, 5 MB) Chapter from textbook, Seminars in Reproductive Endocrinology, 1991. Because of the action at the estrogen-receptor level within the hypothalamus, CC alleviates the negative feedback effect exerted by endogenous estrogens. [161, 162, 163] As a result, CC normalizes the GnRH release; therefore, the secretion of FSH and LH is capable of normalized follicular recruitment, selection, and development to reestablish the normal process of ovulation. [161, 164] The standard dose of CC is 50 mg PO qd for 5 days, starting on the menstrual cycle day 3-5 or after progestin-induced bleeding. The woman may be given a low dose of ovary stimulating hormones. They are then processed and introduced to eggs by different methods. Risk factors for the formation of antisperm antibodies in men include the breakdown of the blood‑testis barrier, trauma and surgery, orchitis, varicocele, infections, prostatitis, testicular cancer, failure of immunosuppression and unprotected receptive anal or oral sex with men.[23][24] Sexually transmitted infections[edit] Infections with the following sexually transmitted pathogens have a negative effect on fertility: Chlamydia trachomatis and Neisseria gonorrhoeae. This method takes several weeks and daily hormone injections are needed to ensure successful implantation. Epididymal and Testicular Spermatozoa and Intracytoplasmic Sperm Injection. (PDF, 7 MB) Assisted Reproduction Reviews, 1996. IUI treatment, where the sperm is transferred into the uterus via the cervix, is commonly used in cases of low sperm count or quality. 4) In Vitro Fertilization (IVF): In vitro means “outside the body.” IVF is a process whereby eggs are collected and then fertilized by sperm outside the body, in an embryology laboratory. A failure of GnRH neurons to migrate to the proper location in the hypothalamus has been implicated. Hysterosalpingogram (HSG) – This test is essential for evaluating fallopian tubal patency, uterine filling defects such as fibroids and polyps, and scarring of the uterine cavity (Asherman syndrome). About 25% of all infertility is caused by an ovulation disorder. When one year of sexual relationships without birth control measures has not lead to a pregnancy. After 3-6 hours, the sperm is added to the oocytes. Less common factors The following other factors may also be responsible for infertility in a smaller proportion of cases: • Genetic abnormalities within eggs, sperm or both • An abnormal uterine cavity, including the presence of fibroids or polyps • Immunological infertility, whereby either the male or female partner produces anti-bodies against sperm cells or implantation of an embryo • Abnormal cervical mucus which hinders the passage of sperm to the uterus and fallopian tubes Unexplained infertility Even when investigations have been extensive, some couples will have no reason with which to explain their infertility.
