Breech Presentation http://www.moondragon.org/obgyn/pregnancy/breech.html
C-Sections • Optimal rate: 10 – 15% • Rate in US: 25.2% • Both are safe in a normal pregnancy • Overall safety difficult to compare (since C-sections are most often done when there are complications
Some Lingering Consequences of C-sections • More post-delivery pain than a vaginal birth • Delayed nursing and bonding • Risk of respiratory problems, even if baby is not premature • Increased risk of adverse outcomes in subsequent pregnancies: placental problems, uterine rupture.
Lupus and Pregnancy • Disease flares and drugs may suppress fertility. • Problems with excessive blood clotting increase risk of miscarriage and premature birth. • It’s unclear whether pregnancy makes lupus worse or better.
Spinal Cord Injury and Sexuality and Pregnancy • Most women with spinal cord injury continue to be sexually active. • Women with spinal cord injuries can have healthy babies, and about half deliver vaginally. • Concerns during pregnancy include: autonomic dysreflexia, urinary tract infections, premature labor, abnormal presentation (i.e. breech), failure of labor to progress, and effects of drugs on the fetus
Common causes of Infertility in Women • Tubal Obstruction • Ovulatory disorders • Polycystic Ovary Disease • Endometriosis

Polycystic Ovary http://medicineworld.org/images/blogs/2-2007/polycystic-ovary-281680.jpg
Polycystic Ovary Disease • Characterized by irregular menstrual periods, and failure to ovulate. • Appears to be due high constant levels of LH • No LH surge, which is needed for ovulation, so the ova and follicles remain in the ovary. • High LH stimulates high levels of testosterone, leading to hirsutism. • Also characterized by obesity and insulin resistance
Endometriosis http://www.whathealth.com/endometriosis/images/endometriosis.jpg
Endometriosis • Characterized by appearance of endometrial tissue outside the uterus. • The misplaced endometrial tissue responds to reproductive hormones the same way the uterine lining does, and therefore there is thickening of tissues during the follicular phase, and bleeding during menstruation. • Women with endometriosis have fertility rates that are about 1/2 those without the disease. However, the mechanism by which this disorder causes infertility is unclear.
