Pregnant women and their partners often ask healthcare professionals whether sex is safe during pregnancy, and what consequences may result from sexual activity. Many clinicians can also be unsure of the answers to these type of questions, leading to both patient and clinician resorting to the internet for advice, which can be inaccurate and anxiety-inducing. Here, the authors provide clinicians with an insight into the information offered by ‘Dr Google’ so that they can reassure and advise their patients as necessary. Aimed at obstetricians and other physicians caring for pregnant women, this book reviews the implications of sex during pregnancy such as those complicated by medical conditions, those at risk of preterm birth and multiple pregnancies. Other chapters cover physiological changes during pregnancy that may affect sexual function and intimacy, as well as the differing guidelines provided by various global obstetric societies.
