Puberty is the hormonally mediated process of physical changes that occur during the transition of childhood to adulthood. Activation of the hypothalamic-pituitary-gonadal axis triggers the onset of puberty. Gonadotropin hormone-releasing hormone (GnRH) is the major regulator of the reproductive axis. GnRH stimulates the anterior pituitary gland to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn activate the gonads to produce sex steroids. Thelarche is stimulated by estrogen and is usually the first sign of puberty in girls. Adrenarche, although associated temporally with puberty, is mediated by the adrenal cortex and is unrelated to pubertal maturation. A growth spurt occurs mid-puberty. Menarche, usually occurring 2-3 years after thelarche, is considered the end of puberty. After menarche, only about 1-2 additional inches of height are accrued. Understanding what is considered the normal timeline of sexual development allows better recognition of precocious or delayed puberty, both of which may be associated with serious underlying health issues This review contains 4 tables, 5 figures, and 29 references. Keywords: puberty, pubertal development, hypothalamic-pituitary-gonadal axis, thelarche, menarche, normal sexual development

Through cellular biopsy of a developing embryo, genetic testing can be performed as part of the embryo selection phase of an in vitro fertilization (IVF) cycle. Preimplantation genetic screening (PGS) and preimplantation genetic diagnosis (PGD) allow embryos to be tested for genetic conditions on a chromosome and gene level, respectively, prior to implantation in the uterus and prior to pregnancy. Included in this review are indications for PGS and PGD, the biopsy and diagnostic methods that are most frequently utilized, advances in recent non-invasive technologies, and potential impacts that PGS/PGD and IVF may have on developing embryos.

Preterm premature rupture of membranes (PPROM) refers to rupture of the fetal membranes prior to 37-0/7 weeks’ gestation and prior to the onset of labor. PPROM complicates 2-4% of singleton pregnancies and 7-20% of twin pregnancies, and has been implicated in 30-40% of preterm births. Antepartum management involves confirming the diagnosis, excluding contraindications to expectant management (such as stillbirth, nonreassuring fetal testing, and intrauterine infection), and continued inpatient care with perinatology/NICU consultation, antenatal corticosteroids, broad-spectrum antibiotics (to prolong latency), and serial fetal surveillance. Delivery is indicated in the setting of nonreassuring fetal testing, intrauterine infection, excessive vaginal bleeding, preterm labor, and/or a gestational age of 34 weeks or beyond. Latency (time from rupture of membranes to delivery) depends on gestational age, severity of oligohydramnios, number of fetuses (shorter in twins), pregnancy complications (placental abruption, infection), fetal wellbeing, and use of broad-spectrum antibiotics. PPROM cannot be accurately predicted or prevented. Appropriate evidence-based management is essential to optimize outcome for both the mother and fetus in the setting of PPROM. This review contains 1 table, 2 figures and 57 references. Key words: chorioamnionitis, preterm birth, perinatal morbidity, twin pregnancies, preterm premature rupture of membranes (PPROM), fetal complications, maternal complications, labor and delivery, inpatient care, antepartum management

One in three women has had at least one urinary tract infection (UTI) treated with antibiotics by the age of 24 years, and half of all women experience a UTI in their lifetime with one in four developing recurrence. Recurrent UTI is defined by two or more symptomatic infections in the past 6 months or three or more symptomatic infections in the past 12 months where each UTI follows a complete resolution of the previous UTI. This review describes the risk factors, diagnosis, work-up and treatment, and prevention of recurrent UTIs. Prevention strategies can be divided into antimicrobial and nonantimicrobial strategies. Nonantimicrobial prevention with behavioral changes, cranberry products, or probiotics did not significantly reduce the occurrence of symptomatic UTIs. Compared with placebo, oral estrogens did not reduce UTIs. However, vaginal estrogens do play a role in prevention of recurrence, particularly in postmenopausal women. There are three main strategies for antibiotic prevention: (1) low-dose daily antimicrobial prophylaxis, (2) postcoital antimicrobial prophylaxis, and (3) patient-initiated antimicrobial treatment. All of these strategies decrease infections during prophylaxis period.The choice of regimen should be based on susceptibilities and antibiotic allergy.

The puerperium starts after the birth of a baby and continues until 6 to 8 weeks postpartum. Several recent interventions in management have been shown to improve outcomes. Delayed cord clamping, the practice of waiting for a period of time after a baby is born before clamping and cutting the umbilical cord, can increase hemoglobin levels, improve iron stores, and increase birth weight in newborns. Rooming in, the practice of mothers and newborns staying together, improves infant sleep and breast-feeding without affecting maternal sleep. Immediately after birth, significant physiologic and anatomic changes occur. Thromboembolic events are more common in the postpartum state than during pregnancy, but the majority of women do not require specific thromboprophylaxis but should be encouraged to walk after birth. Women who have not been previously immunized for influenza; tetanus, diphtheria, pertussis (Tdap); and rubella should be offered these immunizations. Women with uncomplicated pregnancies may engage in exercise within days after delivery. Pelvic floor physical therapy performed during pregnancy and postpartum may assist in maintaining or regaining muscle tone of the pelvic floor and may prevent or treat urinary incontinence. Perinatal depression affects one in seven women. Baby blues, which include mood swings, anxiety, tearfulness, and insomnia, should resolve by 2 weeks after delivery. Patients should be screened for depression using a standardized, validated tool and appropriate treatment initiated. All women should undergo a comprehensive postpartum visit within 6 weeks of delivery.

Symptoms related to fibroids can vary tremendously and depend on the number, size, and location of fibroids, as well as the patient’s hormonal status.

Polycystic ovary syndrome (PCOS) is a highly prevalent endocrine disorder in women of reproductive age. In this review, the pathophysiology and current diagnostic criteria for PCOS are reviewed. Treatment options for symptoms commonly associated with PCOS such as hirsutism, acne, and menstrual irregularity are reviewed. Combined hormonal contraceptives are the first line of therapy in women not attempting pregnancy. The metabolic complications commonly associated with PCOS are impaired glucose tolerance and dyslipidemia. A summary of the current guidelines on screening and prevention of these complications is presented. In addition, PCOS is associated with an increased risk of depressive symptoms and anxiety disorders for which patients should be monitored. This review contains 7 tables and 59 references.

Intrauterine fetal demise (IUFD) and stillbirth are interchangeable terms to describe a fetal death in the second half of pregnancy. IUFD is defined as the delivery of a fetus showing no signs of life as indicated by the absence of heart rate, breathing, umbilical cord pulsation, or voluntary muscle movements. A thorough evaluation of maternal history and risk factors, fetal evaluation involving autopsy and genetic evaluation, and placental pathology should be offered at the time of IUFD diagnosis. Significant counseling should be provided to patients regarding future pregnancies and the risk of recurrence as well as the need for increased antenatal testing and delivery planning in subsequent pregnancies.

Coronaviruses (CoVs) are a group of viral pathogens that infect mammals and birds. The presentation in humans is typically that of a mild upper respiratory tract infection, similar to the common cold. However, in recent years, dramatic attention has arisen for more lethal members of this viral family (e.g., severe acute respiratory syndrome [SARS-CoV], Middle East respiratory syndrome [MERS-CoV], and coronavirus disease 2019 [COVID-19]). The epidemiology, clinical presentation, diagnosis, and management of these viruses are discussed in this review. Importantly, new guideline tables from the Centers for Disease Control and Prevention, as well as the World Health Organization are provided at the conclusion of the review.
