Smoking: Smoking significantly increases the risk of infertility in both men and women, and it may undermine the effects of fertility treatment. Tests and trials are available, but testing does not always reveal a specific cause. New Concepts in Operative Andrology: A Review. (PDF, 7 MB) International Journal of Andrology, 2000. Primary testicular causes of infertility Primary testicular problems may be chromosomal or nonchromosomal in nature.

This process bypasses the normal fertilization process, which may be compromised due to poor sperm function. Some causes are more common in some countries than others, such as pelvic inflammatory diseases (PID) and sexually transmitted infections (STI) in Africa [10]. Blood test: The lab will test for levels of testosterone and other hormones. Local commissioners and providers of healthcare have a responsibility to enable the guideline to be applied when individual professionals and people using services wish to use it. Most of the time, basic semen analysis is all that's needed to diagnose male infertility.

Anatomic causes of infertility include acquired and congenital problems. Patients who do not ovulate because of a fault in the pituitary gland may receive this drug as an injection. In this case, symptoms can also include: Skin changes, including more acne Changes in sex drive and desire Dark hair growth on the lips, chest, and chin Loss of hair or thinning hair Weight gain Other symptoms of disorders that may lead to infertility include: Milky white discharge from nipples unrelated to breastfeeding Pain during sex Many other things can be related to infertility in women, and their symptoms vary.

Endometriosis Endometriosis is a condition where small pieces of the womb lining (the endometrium) start growing in other places, such as the ovaries. Sperm were inserted into the oocyte (bar = 100 µm). (B) Marmoset blastocysts produced by ICSI. (bar = 100 µm). Passing very dark, old blood at the beginning of a period can also be a sign of endometriosis. However, varicoceles may lead to impaired testicular spermatogenesis and steroidogenesis, potentially due to an increased intratesticular temperature, reflux of toxic metabolites, and/or germ cell hypoxia as potential causes of these changes, and this appears to be progressive over time.

Problems with sexual intercourse These can include trouble keeping or maintaining an erection sufficient for sex (erectile dysfunction), premature ejaculation, painful intercourse, anatomical abnormalities such as having a urethral opening beneath the penis (hypospadias), or psychological or relationship problems that interfere with sex. The use of Epididymal and Testicular Sperm for ICSI. (PDF, 1 MB) From IX World Congress on In Vitro Fertilization and Alternated Assisted Reproduction, 1995. In many instances, sterility may be unexplained, but fertility treatments will be able to help. Other factors that can affect a woman's chances of conceiving include being overweight or underweight,[56] or her age as female fertility declines after the age of 30.[57] Sometimes it can be a combination of factors, and sometimes a clear cause is never established. If an endocrinopathy, such as hyperprolactinemia, is diagnosed, the underlying cause should be treated. Ovulation often can be detected by keeping a menstrual calendar or using an ovulation predictor kit. These problems with sperm can cause male infertility. The Disappearing Male. (PDF, 1 MB) From Towards Reproductive Certainty, 1999. Men who are underweight tend to have lower sperm concentrations than those who are at a normal BMI. However, in our modern era, women are delaying child birth until their thirties and forties, which has lead to the discovery of the adverse effect of advanced maternal age on egg function. What Forms of Male Infertility are there left to Cure? (PDF, 2 MB) Human Reproduction, 1995. In addition, antibodies are present in 35% of patients with CBAVD.
