The radiation dose to the ovaries that generally causes permanent female infertility is 20.3 Gy at birth, 18.4 Gy at 10 years, 16.5 Gy at 20 years and 14.3 Gy at 30 years. [32] After total body irradiation , recovery of gonadal function occurs in 10−14% of cases, and the number of pregnancies observed after hematopoietic stem cell ...
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 partners. [29] [5] In 10–20% of cases, no cause is found. [5] The most common cause of female infertility are ovulation problems, usually manifested by scanty or absent menstrual ...
Approximately 20% of female infertility can be attributed to tubal causes. [1] Distal tubal obstruction (affecting the distal tubal opening (towards the ovary)) is typically associated with hydrosalpinx formation and often caused by Chlamydia trachomatis. [1] Pelvic adhesions may be associated with such an infection.
Women in which the presenting symptom is infertility often have diagnoses delayed beyond the average window of 25–29 years of age. [ 6 ] The gold standard for diagnosing endometriosis is a diagnostic laparoscopy , a minimally invasive procedure that involves a camera entering the abdominals through a small incision to examine the abdominal ...
Tubal factors cause 25-30% of infertility cases. [1] Tubal factor is one complication of chlamydia trachomatis infection in women. [2] Sexually transmitted chlamydia and genital mycoplasma infections are preventable causes of infertility and negative pregnancy outcomes. When the infections progress and ascend, they can result in TFI.
Several studies show this test to be more accurate than basal FSH testing for older women (< 44 years of age) in predicting IVF outcome. [17] This method of determining ovarian reserve is recommended by Dr. Sherman J. Silber, author and medical director of the Infertility Center of St. Louis.

20-30% percent of infertility cases are due to male infertility, 20–35% are due to female infertility, and 25-40% are due to combined problems. [13] In 10–20% of cases, no cause is found. [13] The most common cause of female infertility is ovulatory problems, which generally manifest themselves by sparse or absent menstrual periods. [60]
Chronic anovulation is a common cause of infertility. In addition to the alteration of menstrual periods and infertility, chronic anovulation can cause or exacerbate other long-term problems, such as hyperandrogenism or osteopenia. It plays a central role in the multiple imbalances and dysfunctions of polycystic ovary syndrome.
