Seminoma Discovered in Two Males Undergoing Successful Testicular Sperm Extraction for Intracytoplasmic Sperm Injection. (PDF, 807 KB) Human Reproduction, 1995. As a woman gets older, the number of her eggs decreases rapidly. The presence of open tubes is essential for natural conception, as sperm must traverse the tubes in order to reach and fertilize the ovulated egg. The evaluation of the azoospermic male: AUA best practice statement.

Polycystic ovarian syndrome (PCOS) is one of the most common disorders impacting ovulation. Erectile dysfunction or premature ejaculation: Medication, behavioral approaches, or both may help improve fertility. The ordered sequence of release is important for appropriate functioning.

Grading is as follows: Grade 0 – No movement Grade 1 – Sluggish movement Grade 2 – Slow movement in a poorly defined direction Grade 3 – Slow or curved forward movement Grade 4 – Fast movement straight forward  Patients with abnormal sperm motility should be evaluated for the following: Pyospermia Antisperm antibodies Varicocele Sperm ultrastructural abnormalities Partial ductal obstruction Sperm morphology The head, acrosome, mid piece, and tail of individual spermatozoa are analyzed with phase-contrast microscopy after fixation with Papanicolaou stain. The hypothalamus also produces thyrotropin-releasing hormone (TRH) and vasoactive intestinal peptide (VIP), both of which stimulate prolactin release from the anterior pituitary, and dopamine, which inhibits prolactin release. Blocked ovaries can start functioning again without a clear medical explanation. Bromocriptine and cabergoline are dopamine agonists used to suppress prolactin levels. Testosterone is converted to dihydrotestosterone (DHT) by the action of 5-alpha reductase, both locally and in the periphery, and to estrogen in the periphery.

Four alternatives are currently available to treat endometriosis: expectant therapy, surgical intervention, medical treatment, and combined therapy. Irregular ovulation can be due to many issues, including polycystic ovary syndrome (PCOS), obesity, being underweight, and thyroid issues.

Primary vs. secondary infertility[edit] Primary infertility is defined as the absence of a live birth for women who desire a child and have been in a union for at least 12 months, during which they have not used any contraceptives.[14] The World Health Organisation also adds that 'women whose pregnancy spontaneously miscarries, or whose pregnancy results in a still born child, without ever having had a live birth would present with primarily infertility'.[15] Secondary infertility is defined as the absence of a live birth for women who desire a child and have been in a union for at least 12 months since their last live birth, during which they did not use any contraceptives.[15] Thus the distinguishing feature is whether or not the couple have ever had a pregnancy which led to a live birth.

For unknown reasons, as women age, egg numbers decrease at a rapid rate. Recent Advances in Male Reproductive Surgery. (PDF, 10 MB) Chapter 13 from Annual Progress in Reproductive Medicine, 1993. Intracytoplasmic Sperm Injection. (PDF, 4 MB) Chapter 47 from textbook Current Therapy in Equine Reproduction, 2006. This measurement is called the antral follicle count and may correlate with fertility potential. 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. In those with azoospermia and a varicocele, sperm may appear after repair in up to one third, but most of these men return to an azoospermic state within a few months. In closed social groups, a degree of rejection (or a sense of being rejected by the couple) may cause considerable anxiety and disappointment. The rising number of obese individuals may be due in part to an energy-rich diet as well as insufficient physical exercise.  In addition to other potential health risks, obesity can have a significant impact on male and female fertility.
