Polycystic ovary syndrome PCOS is a heterogeneous disorder consisting of clinical or biochemical hyperandrogenism with ovulatory dysfunction ruling out secondary causes for the same. The reproductive issues with PCOS are manifold starting with anovulatory cycles leading to subfertility.
After having successfully passed the first trimester, they commonly encounter later pregnancy complications like gestational diabetes mellitus GDM , pregnancy-induced hypertension PIH , preeclampsia, preterm delivery, and birth of small for gestational age SGA infant. Effective tackling of metabolic and reproductive issues relating to pregnancy forms the cornerstone of management of PCOS. Normal pregnancy is characterized by induction of insulin resistance associated with compensatory hyperinsulinemia in second and third trimesters.
This insulin resistance of normal pregnancy is a physiologically advantageous adaptation designed to restrict maternal glucose uptake and to ensure shunting of nutrients to the growing fetus. It is probably mediated by increases in hormonal levels of estradiol, progesterone, prolactin, cortisol, human chorionic gonadotropin, placental growth hormone PGH , and human placental lactogen HPL. HPL is responsible for adaptive increase in insulin secretion necessary for pregnancy and for diversion of maternal carbohydrate metabolism to fat metabolism in the third trimester.
PGH seems to be a paracrine growth factor probably regulating the metabolic and growth needs of the fetus partially. Barbour, et al. In normal pregnancy, there is a decreased expression of the GLUT-4 transporter in maternal adipose tissue[ 7 ] but not in skeletal muscle.
Skeletal muscle is the main site of insulin-mediated glucose disposal in vivo. Hence, the mechanisms for insulin resistance in normal pregnancy lie in the skeletal muscle either in the insulin signaling pathways or in the abnormal GLUT-4 translocation. Hyperandrogenism and insulin resistance form the metabolic hallmark of PCOS women.
A significant section of lean PCOS women have baseline intrinsic insulin resistance. Those with superimposed obesity have additional insulin resistance contributed by the excess adipose tissue.
The baseline insulin resistance seems to be exacerbated with entry into pregnancy. There is an increased risk of pregnancy complications in PCOS women. In a population-based cohort study, women with PCOS were more often obese and more commonly used assisted reproductive technology than women without such a diagnosis.
Treatment with ovulation-inducing agents is associated with a higher incidence of spontaneous EPL compared with the prevalence in the normally ovulating, naturally conceiving population. The likelihood of miscarriage was increased and conception rate decreased as compared to those with normal LH in PCOS women.
Apparao, et al. High plasminogen activator inhibitor-1 PAI-1 activity has been found to be associated with recurrent pregnancy loss in women with unexplained recurrent miscarriages and has also been found to be significantly higher in women with PCOS independent of BMI. Glueck, et al. PCOS women are believed to be strongly associated with insulin resistance and compensatory hyperinsulinemia,[ 28 ] which has been shown to be independently contributed by obesity prevalent among PCOS women.
However, the exact mechanism for it remains elusive currently, although different factors for its effect have been proposed. Impaired glucose uptake caused by downregulation of the IGF-I receptor has been documented to result in blastocyst apoptosis. Implantation of embryo is affected by the endometrial receptivity which seems to be affected in PCOS. Glycodelin may be involved in early placental development through its modulatory effect on immune and trophoblast cells.
Increased risk of miscarriage was found in a meta-analysis investigating the association between obesity and miscarriage. Wang, et al. Some among these had obesity as a confounding factor and hence could have increased the actual risk. Urman, et al. Diamant, et al. Haakova, et al. Preeclampsia itself is a risk factor for preterm deliveries.
Meta-analysis by Boomsma, et al. Insulin resistance, both intrinsically and that due to superimposed obesity, forms the most important pathogenetic mechanism for PCOS complications. It therefore seems logical to treat PCOS complications with insulin sensitizers. Metformin is the commonly used insulin sensitizer. Most studies which showed the benefit of metformin in reducing EPL were either observational studies or non-randomized trials, unadjusted for major confounders and included small number of subjects [ Table 1 ].
There is still insufficient evidence for use of metformin during pregnancy. Palomb,a et al. They concluded that metformin has no effect on the miscarriage risk in PCOS women when administered before pregnancy.
Although the safety of metformin for fetus in pregnancy has been documented in many studies, its use in pregnancy persists to be a contentious issue. Currently, metformin has been recognized by FDA as a class B for use in pregnancy, which means that either animal-reproduction studies have not shown a fetal risk without corresponding controlled studies in women, or animal studies have shown an adverse effect not confirmed by controlled studies in women.
Characteristics of important studies assessing the effect of metformin on pregnancy complications in PCOS women.
The use of metformin for control of glucose intolerance in PCOS remains a controversial issue. In the recent Metformin in Gestational Diabetes MIG trial comparing metformin and insulin treatment in GDM, there was no significant difference in the composite fetal outcome between the metformin and insulin groups. Vanky, et al. Women in the metformin group gained less weight during pregnancy compared with those in the placebo group.
There was no difference in fetal birth weight between the groups. They found no evidence for use of metformin throughout all trimesters to reduce pregnancy complications in PCOS women.
In the circumstance of PCOS woman becoming pregnant while being on metformin therapy, it would be advisable to stop metformin once pregnancy is confirmed.
Further high-level evidences from large-scale well-powered, placebo-controlled randomized trials are required for formulation of recommendations for management of pregnancy of PCOS women. Women with PCOS are at increased risk of adverse pregnancy and birth outcomes and may need increased surveillance during pregnancy and parturition. There is no evidence for benefit of metformin in management of these pregnancy complications pending further well-powered placebo-controlled randomized trials analyzing it.

Pregnant with polycystic ovary. What causes PCOS?
Polycystic Ovary Syndrome (PCOS) | Your Fertility
The most successful way to treat PCOS is by living a healthy life. Polycystic ovary syndrome PCOS is the most common hormonal condition affecting women in their reproductive years. Around one in seven women have PCOS which can cause a range of symptoms such as; irregular periods menstruation , skin and hair changes and for some women, difficulties getting pregnant.
If the hormone levels associated with PCOS can be reduced or controlled, the ovaries can often function normally. The causes of PCOS are not fully understood. Genetics family inheritance , hormones that are increased during development in the uterus before birth, and lifestyle factors all play a role.
PCOS is called a syndrome which means it is characterised by a range of symptoms, which differ widely between individuals. They affect three main areas: reproductive, metabolic and psychological health.
If you have other conditions that can appear similar to PCOS, they need to be checked by your doctor and excluded before a PCOS diagnosis can be confirmed. PCOS is difficult to diagnose in women taking the contraceptive pill as this medication alters hormone levels. If an accurate diagnosis is needed, women need to stop taking the pill for three months beforehand and use a different method of contraception during this time. A blood test will measure the level of male type hormones androgens, also called testosterone and exclude other conditions.
A vaginal ultrasound takes a picture of the ovaries. If there are 20 or more follicles fluid filled sacs on either ovary, this indicates PCOS. While 30 percent of women with PCOS have no problem, around 70 percent have some difficulties getting pregnant.
For women who may have difficulties becoming pregnant, starting earlier in life, if possible, offers more time to try a range of fertility treatment options. Ricci-Jane and her partner were told they wouldn't have a baby without IVF. Ricci-Jane had PCOS, and a stressful new job and poor eating habits had taken their toll on her body. Your GP can refer you to a fertility specialist for specific treatments. There are a range of medications that can be very effective in helping women with PCOS to become pregnant.
If women are an older age or an unhealthy weight, this can affect their chances of a successful pregnancy. Read the PCOS fact sheet for more detailed information about treatment options and how you can improve your chances of having a baby.
The Association brings together women, their families and friends, and medical professionals interested in supporting the group and PCOS patients. This includes IVF, surrogacy and donor-conception. Polycystic ovary syndrome PCOS is the most common hormonal condition affecting women in their reproductive years What men and women can do to increase their chance of getting pregnant and having a healthy baby Share Back to Top.
Main points PCOS can be associated with a range of symptoms including irregular periods and difficulties getting pregnant.
Most women with PCOS can conceive, however it may take them a little longer to become pregnant. What is PCOS? PCOS is mainly due to a hormonal imbalance rather than a disease of the ovaries. What causes PCOS? What are the symptoms of PCOS? PCOS symptoms vary not only between individuals, they also vary at different stages of life. The number of symptoms women experience varies among individuals. How is PCOS diagnosed? If women have two of these three criteria, it is likely that they will be diagnosed with PCOS: If you have other conditions that can appear similar to PCOS, they need to be checked by your doctor and excluded before a PCOS diagnosis can be confirmed.
