Study Notes
Male Reproductive System
- Ejaculatory duct transports lubricated sperm from the seminal vesicle.
- Prostate gland's primary function is fluid secretion, aiding in sperm transport.
- Sperm must enter the cervix to reach the uterus, accomplishing this within 90 minutes and aiming for the fallopian tubes in 5 minutes.
- Oligospermia is defined as a low sperm count, specifically fewer than 20 million sperm per mL.
Female Reproductive System
- Vestibule refers to the space inside the labia minora.
- Skene's gland lubricates the urethra.
- Bartholin's glands provide lubrication for the vaginal canal.
- Urethral meatus is the initial opening leading to the urinary bladder.
Uterine Positions and Conditions
- Non-pregnant retroflexed uterus can lead to rectocele, causing defecation difficulties and pain.
- Non-pregnant anteflexed uterus can lead to cystocele, which puts pressure on the urinary bladder.
- Uterus is positioned between the urinary bladder in front and the rectum behind.
Uterine Positions
- Anteverted position: Slightly leans forward, considered normal.
- Anteflexion position: Sharply leans forward.
- Retroverted position: Normal during pregnancy.
- Retroflexion position: Abnormal positioning of the uterus.
Placenta Conditions
- Placenta accreta occurs when the placenta attaches to the myometrium, complicating delivery. If separation does not occur post-delivery, hysterectomy may be necessary.
Myometrium and Contractions
- The thickest layer of the myometrium is found in the fundus, the upper segment of the uterus.
- Oxytocin is critical for stimulating rhythmic uterine contractions, aiding in childbirth.
Fallopian Tubes
- Fallopian tubes consist of three regions: narrowest at the interstitial, middle section (isthmus), and widest at the ampulla.
- Fimbriae have openings that help catch the egg released from the ovary.
- Ampulla is the common site of fertilization; interstitial is the most dangerous implantation site.
Medication Effects
- Bricanyl or Terbutaline function as smooth muscle relaxants and bronchodilators, useful during labor to manage contractions.
