Study Notes
Reproductive System Overview
- Anatomy and physiology of male and female reproductive systems are critical for reproductive health education.
- Key areas of care include understanding reproductive health and sexuality for improved nursing practices.
Reproductive Development
- Gonads are differentiated as testis in XY chromosomes and ovaries in XX chromosomes.
- Primitive gonadal tissues appear at 5 weeks of intrauterine life, leading to sex differentiation.
- Presence of testosterone at 7-8 weeks develops male reproductive organs, while absence leads to female organ development.
Pubertal Development
- Secondary sexual characteristics emerge between ages 9-17, generally 9-12 for girls and 12-14 for boys.
- Androgen sources include adrenal cortex and gonads in both genders.
Tanner’s Sexual Development - Females
- Acceleration in linear growth, pelvis widening, breast development (thelarch), and pubic hair growth occur in succession.
- Menarche marks the onset of menstruation, followed by vaginal secretions and axillary hair growth.
Tanner’s Sexual Development - Males
- Male puberty features weight increase, testicular growth, development of facial, axillary, and pubic hair, voice changes, and penile growth.
- Height increase and initiation of spermatogenesis complete the male secondary sex characteristics.
Male Reproductive System
- External structures include the penis and scrotum.
- Internal structures are designed to support reproductive functions and processes.
Female Reproductive System
- External structures play roles in intercourse and protection.
- Internal structures include ovaries, fallopian tubes, uterus, cervix, and vagina.
Ovaries
- Size: approximately 4 cm x 2 cm, color: grayish-white.
- Functions as a sex gland, site of oogenesis, and producer of estrogen and progesterone.
- Three divisions: surface epithelium, cortex, and medulla.
Fallopian Tubes
- Length: 3-4 inches; consists of interstitial, isthmus, ampulla, and infundibulum parts.
- Functions as the site of fertilization and transport of ovum to the uterus.
Uterus Functions
- Main roles include implantation of fertilized ovum, nourishment of conception products, labor assistance, and menstruation.
- Structure divided into layers: perimetrium (outer), myometrium (middle), endometrium (inner).
Uterine Blood Supply
- Blood supply originates from descending aorta, with specific arteries including iliac, hypogastric, and uterine arteries.
Uterine Nerve Supply
- Comprised of afferent sensory nerves from T11 to T12 and efferent motor nerves from T5 to T10.
Cervical Anatomy
- Parts include Internal os (effaces), cervical canal (operculum), and external os (dilates).
Vagina
- Length ranges between 3-4 inches; functions include facilitating intercourse, menstruation, and childbirth.
- Maintains an acidic environment due to the presence of Doderlein bacillus.
Breast and Mammary Glands
- Mammary glands are crucial for lactation and encompass lobules, acini cells, and ducts for milk ejection, stimulated by oxytocin during suckling.
