1. Male 
Reproductive 
System
1.1- Testes
Located in scrotum, maintain lower 
temperature for spermatogenesis
Contains seminiferous tubules for sperm 
production
Leydig cells produce testosterone
1.2- Accessory
 Ducts
Includes Rete Testis, Vasa e?erentia, 
Epididymis, Vas deferens
Transport sperms from testes to urethra
1.3- Glands
Seminal vesicles, Prostate, Bulbourethral 
glands contribute to seminal plasma
1.4- External 
Genitalia
Penis, responsible for insemination
2. Female 
Reproductive 
System
2.1- Ovaries
Produce ovum and hormones, located in 
lower abdomen
2.2- Oviducts Transport ovum from ovary to uterus
2.3- Uterus
Site of fetal development, undergoes 
menstrual cycle
2.4- External
 Genitalia
Includes vagina, labia, hymen, clitoris
2.5- Mammary 
Glands
Produce milk for o?spring
3. Gametogenesis
3.1- Spermatogenesis Formation of sperms in testes
3.2- Oogenesis Formation of ova in ovaries
4. Menstrual
 Cycle
4.1- Includes menstrual, 
follicular, luteal phases
4.2- shedding of the lining of your uterus.
4.3- Prepares uterus for pregnancy
5. Fertilization
5.1- Union of sperm and ovum to form 
zygote
5.2- Fertilization, union of a sperm 
nucleus, with an egg nucleus,to form the 
primary nucleus of an embryo. 
6. Embryonic 
Development
6.1- Formation and growth of embryo and 
fetus
6.2- Embryo development refers to the 
di?erent stages in the development of an 
embryo. 
7. Parturition and Lactation
7.1- Birth process and milk production for 
newborn
7.2- Removal  the foetus from the 
mother’s womb is known as parturition.
7.3- The process of making and secreting 
milk from the mammary glands to feed 
the infant is known as lactation
