  • Front
  • Back
Part of spermatozoa that contains genetic information
• The head contains the nucleus with genetic material,
Ovulation definition
Ovulation is the process in a female's menstrual cycle by which a mature ovarian follicle ruptures and discharges an ovum
About day 14
Surge of LH causes ovum to burst
Ruptured follicle transforms into corpus luteum
• Mixture of sperm and secretions of accessory sex glands
• Averages 3-5 mL per ejaculation
• Each mL containing about 100,000,000 sperm
• Sperm passes through the ejaculatory ducts and mixes with fluids from the seminal vesicles, the prostate, and the bulbourethral glands to form the semen.
hromosome is an organized building of DNA and protein that is found in cells. It is a single piece of coiled DNA containing many genes, basic unit of heredity
Secondary sex Characteristics
Develops secondary sex characteristics:

• Deeper voice
• Broader shoulders
• Narrower hips
• Mores body hair
• Protein anabolism
• Development of muscle strength (more muscle tissue)
Sex cells # of chromosomes
location and function of ovaries
• Paired glands weighing about 3 g each
• Resemble large almonds
• Located in region called ovarian fossa
• Attached to ovarian ligaments in pelvic cavity on each side of uterus
Seminal Vessicles
• Seminal vesicles produce a yellowish viscous fluid rich in fructose and other substances that makes up about 70% of human semen.
Spermatic cord
The spermatic cord is the name given to the cord-like structure in males formed by the ductus deferens and surrounding tissue that run from the abdomen down to each testicle. Contains arteries and nerves
what do testes produce?
Where is sperm stored?
Ovaries Ligaments
The ovarian ligament (also called the utero-ovarian ligament or proper ovarian ligament) is a fibrous ligament that connects the ovary to the lateral surface of the uter

suspensory ligament of the ovary, also infundibulopelvic ligament (commonly abbreviated IP ligament or simply IP), is a fold of peritoneum[1] that extends out from the ovary to the wall of the pelvis
Acrosome in sperm
• acrosome, which contains enzymes used for penetrating the female egg. It aids in penetration of the ovum.
• Menstruation ceases
• Normal ovarian function declines
• Follicles stop ripening
• No appreciable amounts of estrogen produced
• Uterus, oviducts, vagina, vulva become somewhat atrophied
• Vaginal mucosa becomes thinner, dryer, more sensitive
1. Sperm precursor cells; Spermatogonia
2. Meiosis produces primary spermatocyte
3. Forms four spermatids with 23 chromosomes
4. Spermatids mature into Spermatozoa

spermatogonia ----> spermatocytes ------> spermatids -----> sperm
• Oogonium becomes Primary Oocyte
• Meiosis
• First Polar Body (Discarded) + Secondary oocyte form
• Meiosis II
• Secondary Polar Body (Discarded afterward) + Ovum formed
