Study Notes

SEXUAL RESPONSE CYCLE

  • Sexual response cycle characterized by increased heart rate, muscle tension, and vasocongestion leading to heightened sensitivity and excitement. This is the excitement phase.
  • Positive psychological states enhance sexual pleasure, while stress or anxiety diminish arousal during the plateau phase.
  • Males typically experience more intense, shorter orgasms, while females can have multiple orgasms with varying intensity.
  • Hormones like oxytocin and prolactin promote relaxation and bonding, helping the body return to a baseline state during the resolution phase.
  • External factors like relationship dynamics and stress can negatively affect arousal and enjoyment in any phase of the cycle.

FERTILIZATION

  • Sperm preventing polyspermy is primarily done via the cortical reaction.
  • Fertilization enhances genetic diversity through random allele combination from two parents.
  • The zona pellucida acts as a barrier for sperm penetration during fertilization.

IMPLANTATION

  • The endometrium thickens and secretes nutrients and signaling molecules to prepare for implantation.
  • Inadequate progesterone may lead to embryo expulsion.
  • Presence of uterine abnormalities can negatively influence implantation.
  • Cytokines and growth factors promote communication between the growing embryo and endometrium, facilitating attachment and implantation.
  • The blastocyst stage allows embryo implantation into the uterine wall.
  • Invasion and remodeling of maternal tissue by the trophoblast occurs.
  • Maternal immune system response supports embryo implantation by suppressing activity to tolerate it.
  • Human Chorionic Gonadotropin (hCG) helps maintain progesterone production in early pregnancy and is an indicator of potential pregnancy.
  • A failed implantation can result in a chemical pregnancy.
  • Ectopic pregnancy can result from abnormal fallopian tubes.
  • Endometrial receptivity timing and success of embryo attachment are important factors in successful implantation.
  • Implantation is crucial for embryonic development because of the transfer of nutrients.
  • A proper maternal diet during implantation can enhance endometrial receptivity.

ESTIMATED DATE OF CONFINEMENT (EDC)

  • Naegele's rule is useful for calculating an estimated date of confinement using a woman's last menstrual period (LMP).

FUNDAL HEIGHT

  • A measurement of the size of the uterus at different stages of pregnancy can help doctors assess fetal growth.
  • Fundal height measurements in centimeters should accurately reflect fetal development during pregnancy.
  • McDonalds rule and Bartholomews rule are useful ways to understand normal fetal growth.

LABOR

  • Maternal anxiety and stress can affect labor progression.
  • Obesity during pregnancy increases the risk of complications during labor.
  • Staying mobile and changing positions during labor can improve progression.
  • Risk of post-term complications increase as pregnancy lengthens beyond 41 weeks.
  • Supportive partners can impact successful coping mechanisms and emotional support.
  • Braxton Hicks contractions are intermittent, irregular uterine contractions and are not true markers of labor.
  • Regular, consistent contractions are associated with the start of active labor.
