The main potential factors that influence pregnancy (and live birth) rates in IVF have been suggested to be maternal age, duration of infertility or
, bFSH and number of oocytes, all reflecting ovarian function. Optimal woman’s age is 23–39 years at time of treatment.
There is no cure or treatment for testicular microlithiasis, however, patients may be monitored via ultrasound to make sure that other conditions do not develop. Emphasis on testicular examination is the recommended follow up for asymptomatic men incidentally identified with testicular microlithiasis. For men with risk factors for testicular germ cell tumor such as
however, individualized discussion with their urologists is necessary.
Folate is necessary for fertility in both men and women. It contributes to spermatogenesis. Therefore, it is necessary to receive sufficient amounts through the diet to avoid
. Also, polymorphisms in genes of enzymes involved in folate metabolism could be one reason for fertility complications in some women with unexplained infertility.
Vitamin E helps counter oxidative stress, which is associated with sperm DNA damage and reduced sperm motility. A hormone-antioxidant combination may improve sperm count and motility. Oral antioxidants given to males in couples undergoing in vitro fertilisation for male factor or unexplained
result in significantly higher live birth rate.
Usage of assisted reproductive technology including ovarian stimulation and in vitro fertilization have been associated with an increased overall risk of childhood cancer in the offspring, which may be caused by the same original disease or condition that caused the infertility or
in the mother or father.
Without technological intervention, a non-motile or abnormally-motile sperm is not going to fertilize. Therefore, the fraction of a sperm population that is motile is widely used as a measure of semen quality . Insufficient sperm motility is a common cause of
or infertility. Several measures are available to improve sperm quality.
is associated with preterm birth. Couples who have tried more than 1 year versus those who have tried less than 1 year before achieving a spontaneous conception have an adjusted odds ratio of 1.35 (95% confidence interval 1.22-1.50) of preterm birth. Pregnancies after IVF confers a greater risk of preterm birth than spontaneous conceptions after more than 1 year of trying, with an adjusted odds ratio of 1.55 (95% CI 1.30-1.85).
WNT4 is involved in a couple features of pregnancy as a downstream target of BMP2. For example, it regulates endometrial stromal cell proliferation, survival, and differentiation. These processes are all necessary for the development of an embryo. Ablation in female mice results in
, with defects in implantation and decidualization. For instance, there is a decrease in responsiveness to progesterone signaling. Furthermore, postnatal uterine differentiation is characterized by a reduction in gland numbers and the stratification of the luminal epithelium.
Cynthia (Cindy) Margaret Farquhar (born August 12, 1956) is the Postgraduate Professor of Obstetrics and Gynaecology in the Department of Obstetrics and Gynaecology at the University of Auckland. Within the Cochrane Collaboration, she is the Coordinating Editor of the Cochrane Menstrual Disorders and
Group and Co-Chair of the Cochrane Steering Group. Farquhar has over 200 published papers, with a focus on women's reproductive and sexual health.
The presence of anti-thyroid antibodies is associated with an increased risk of unexplained
(odds ratio 1.5 and 95% confidence interval 1.1–2.0), miscarriage (odds ratio 3.73, 95% confidence interval 1.8–7.6), recurrent miscarriage (odds ratio 2.3, 95% confidence interval 1.5–3.5), preterm birth (odds ratio 1.9, 95% confidence interval 1.1–3.5) and maternal Postpartum thyroiditis (odds ratio 11.5, 95% confidence interval 5.6–24).
A survey study has indicated that the LEEP procedure does not appear to affect fertility. On the other hand, a case-control study has found an association between surgical treatment of CIN lesions and risk of infertility or
, with an odds ratio of approximately 2. Scarring of the cervix is a theoretical mechanism of causing trouble conceiving. This scar tissue can be massaged or broken up in a number of ways, thus allowing the cervical opening to dilate back to normal size.
Increasing body weight is also thought to be linked to the development of polycystic ovary syndrome (PCOS). There are specific aspects associated with PCOS allowing an indication of diagnosis of the syndrome including hyperandrogenism (hirsutism), irregular periods, anovulation and
. Obesity in PCOS sufferers amplifies hormonal and metabolic decline, therefore damaging fertility and oocyte quality in women. PCOS can also have an effect if conception is successful through assisted reproductive technology (ART) in obese patients, leading to an increase in miscarriage rates.
There are many genes wherein mutation causes female infertility, as shown in table below. Also, there are additional conditions involving female infertility which are believed to be genetic but where no single gene has been found to be responsible, notably Mayer-Rokitansky-Küstner-Hauser Syndrome (MRKH). Finally, an unknown number of genetic mutations cause a state of
, which in addition to other factors such as environmental ones may manifest as frank infertility.
For women, intake of antioxidants (such as N-acetyl-cysteine, melatonin, vitamin A, vitamin C, vitamin E, folic acid, myo-inositol, zinc or selenium) has not been associated with a significantly increased live birth rate or clinical pregnancy rate in IVF according to Cochrane reviews. The review found that oral antioxidants given to men in couples with male factor or unexplained
may improve live birth rates, but more evidence is needed.
