Ovulation disorders can be due to: Premature ovarian failure: The ovaries stop working before the age of 40 years. These factors may interfere with embryo implantation and a woman’s ability to carry pregnancy to term.

Symptoms depend on what is causing the infertility. In fact, female age-related infertility is the most common cause of infertility today.

An ultrasound scan can detect an ectopic pregnancy. Of azoospermic patients with Klinefelter syndrome, 20% show the presence of residual foci of spermatogenesis. Fertility is not an issue for some patients affected by DES, and they remain undiagnosed until they have an abnormal Papanicolaou test result. Testicular histology typically reveals a decreased number of Leydig cells and decreased spermatogenesis. Infertility may be caused by blockage of the Fallopian tube due to malformations, infections such as chlamydia or scar tissue.

For those interested, we offer a free class entitled, “The Couple’s Guide to IVF”, that meets twice monthly and is open to the public. Conventional IVF vs ICSI (Intra Cytoplasmic Sperm Injection) for Patients Requiring Microsurgical Epididymal Sperm Aspiration (MESA). (PDF, 4 MB) Chapter from textbook, Frontiers in Endocrinology: Perspectives on Assisted Reproduction, 1994. For a man to be fertile, the testicles must produce enough healthy sperm to be ejaculated effectively into the woman's vagina. Patients are at increased risk of infertility, even if the testicle is brought down into the scrotum, as the testicle itself may be inherently abnormal. 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. However there is a minimal increased risk of de-novo chromosomal abnormalities in ICSI born babies [46,47] that necessitate counselling of the concerned couples.Infertility is the inability of a person, animal or plant to reproduce by natural means. Some methods may be used in concert with other methods. A doctor injects sperm directly into the egg in a dish and then places it into your uterus. Exposure to some chemicals: Some pesticides, herbicides, metals, such as lead, and solvents have been linked to fertility problems in both men and women. About half the women with hormonal imbalances do not produce enough follicles to ensure the development of an ovule, possibly due to poor hormonal secretions from the pituitary gland or the hypothalamus. 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. Several studies have demonstrated that an increase in BMI is correlated with a decrease in sperm concentration, a decrease in motility and an increase DNA damage in sperm. An obstruction can occur anywhere in the plumbing between the testicles and the penis. Sperm retrieval for azoospermia and intracytoplasmic sperm injection success rates – A personal overview.
