Men who are underweight tend to have lower sperm concentrations than those who are at a normal BMI. This was set up on 1 August 1991 following a detailed commission of enquiry led by Mary Warnock in the 1980s A similar model to the HFEA has been adopted by the rest of the countries in the European Union. A Modern View of Male Infertility. (PDF, 7 MB) From The Infertile Male: Advanced Assisted Reproductive Technology, 1994. These specimens benefit most from layering a washed pellet of sperm with nutrient media and allowing the motile fraction to swim up into the media before being separated. [109] After sperm preparation, the spermatozoa are enhanced in motility and become activated and ready to fertilize an oocyte. The final third may be due to a combination of both, other factors, or unknown causes. 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.

After injection of the sperm, the patient remains in the recumbent position for 10-15 minutes. Kallmann syndrome has been described in both familial (X-linked and autosomal) and sporadic forms, and its incidence is estimated as 1 case per 10,000-60,000 births. Many more couples, however, experience involuntary childlessness for at least one year: estimates range from 12% to 28%.[4] Male infertility is responsible for 20–30% of infertility cases, while 20–35% are due to female infertility, and 25–40% are due to combined problems in both parts.[2][5] In 10–20% of cases, no cause is found.[5] The most common cause of female infertility is ovulatory problems, which generally manifest themselves by sparse or absent menstrual periods.[6] Male infertility is most commonly due to deficiencies in the semen, and semen quality is used as a surrogate measure of male fecundity.[7] Women who are fertile experience a natural period of fertility before and during ovulation, and they are naturally infertile for the rest of the menstrual cycle. If a woman has an ovulation disorder, she may ovulate infrequently or not all. Low weight: Obesity is not the only way in which weight can impact fertility. These endometrial cells can extend as far as the outside of the fallopian tubes, the ovaries and the bladder.

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. This can make it difficult for the embryo to implant. In most cases however, sperm function may not improve and therefore any attempts at pregnancy may require additional treatments or procedures performed by our clinic. The severity usually depends on how near to the testicles the radiation was aimed. This abnormality is usually surgically corrected in infancy. Varicocele A varicocele is a swelling of the veins that drain the testicle, which can impact sperm quality.

Normal uterine implantation can therefore not occur. 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. However, there are side effects to using fertility drugs, such as ovarian hyperstimulation or the increased chance of developing ovarian tumors.  Surgical procedures: These surgeries correct abnormalities or blockages in the uterus and fallopian tubes. Erectile Disfunction (ED): Also known as impotence, this condition is common and affects 20 million American men.  ED is the result of a single, or more commonly a combination of multiple factors.  In the past, ED was thought to be the result of psychological problems, but new research indicates that 90 percent of cases are organic in nature.  However, most men who suffer from ED have a secondary psychological problem that can worsen the situation like performance anxiety, guilt, and low self-esteem.  Many of the common causes of impotence include:  diabetes, high blood pressure, heart and vascular disease, stress, hormone problems, pelvic surgery, trauma, venous leak, and the side effects of frequently prescribed medications (i.e. The Use of Epididymal Sperm in Assisted Reproduction.
