Less than 50% motility may significantly affect the ability for sperm to fertilize the egg without therapy; and (4) morphology, or shape – there are three parts of the sperm that are analyzed for morphology: the head, midpeice, and tail. Hyperprolactinemia: If prolactin levels are high, and the woman is not pregnant or breastfeeding, it may affect ovulation and fertility. Recombination Between Palindromes P5 and P1 on the HUman Y Chromosome Causes Massive Deletions and Spermatogenic Failure. (PDF, 786 KB) The American Journal of Human Genetics, 2002. If he has two X chromosomes and one Y chromosome, as in Klinefelter's syndrome, the testicles will develop abnormally and there will be low testosterone and a low sperm count or no sperm.

For patients with a history of endometriosis, pelvic infections, or ectopic pregnancy, evaluation with hysteroscopy or laparoscopy is recommended. Some causes, such as hyperprolactinemia, are reversible with proper treatment. The sperm must provide the zygote with DNA, centrioles, and activation factor for the embryo to develop. Infertility rates have increased by 4% since the 1980s, mostly from problems with fecundity due to an increase in age.[72] Fertility problems affect one in seven couples in the UK. Painful or heavy periods Most women experience cramps with their periods. Consequently, the patient with PCOS becomes responsive to CC ovulation induction.

Only 5-10% of these couples eventually achieve a pregnancy within 5 years. Thus 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. (Trends in prevalence4). 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.

Predominantly anovulation is caused by hormonal imbalances such as Polycystic Ovarian Syndrome (PCOS) but ovarian scarring and premature menopause can also result in failure to ovulate. • Tubal disease, comprising anything from mild adhesions to complete blockage of the fallopian tubes, prevents fertilised eggs from travelling from the site of fertilisation to the uterus. Open-ended Vasectomy, Sperm Granuloma, and Postvasectomy Orchialgia. (PDF, 13 MB) Fertility and Sterility, 1979. Ultrasound can help us discover abnormalities with the uterus, fallopian tubes and/or ovaries. For this reason, it is less likely to adversely affect the endometrium and cervical mucus. In cases when the quality of sperm is very poor, or sperm is completely absent in the ejaculate (azoospermia), donor’s sperm can be used (if culturally acceptable). This should be followed by documentation of ovulation via serum progesterone.

The avascular nature of the septum is theorized to interfere with implantation and maintenance of the embryo. Factors contributing to the formation of antisperm antibodies in women are disturbance of normal immunoregulatory mechanisms, infection, violation of the integrity of the mucous membranes, rape and unprotected oral or anal sex. Mental stress: This may affect female ovulation and male sperm production and can lead to reduced sexual activity. It is usually not the natural state of a healthy adult, except notably among certain eusocial species (mostly haplodiploid insects). Sperm retrieval for azoospermia and intracytoplasmic sperm injection success rates – A personal overview. (PDF, 1 MB) Human Fertility, 2010. The laboratory evaluation begins with a semen analysis. Additional risk factors may include smoking, alcohol use, obesity, and older age; however, the data are hampered by a lack of pregnancy-related outcomes. Most problems are related to premature labor and pregnancy loss. This technique should be reserved for myomas with a diameter less than 6 cm. [123] Several cases have been reported of uterine rupture during pregnancy because the reconstruction of the uterus after laparoscopic myomectomy was not as good as a myomectomy performed using laparotomy. [124] Operative hysteroscopy: The removal of a submucous fibroid using hysteroscopy should be limited to small fibroids (≤3 cm) with minimal compromise of the myometrium. [81] This is important to decrease the risk of excessive bleeding and to decrease the risk of electrolyte imbalance, water intoxication, and pulmonary edema from excessive intravasation of Hyskon, glycine, or sorbitol used during the procedure. If a woman has an ovulation disorder, she may ovulate infrequently or not all. The success rate of IVF for live birth is 40% among women under 35 years of age. Oligospermia is the most frequent cause of male infertility. A small incision is made in the abdomen, and a thin, flexible microscope with a light at the end, called a laparoscope, is inserted through it. Effectiveness of the postcoital test: randomised controlled trial. Other conditions that affect the quality and quantity of sperm include: Primary testicular failure. 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).
