Study Notes
Male Reproductive System Functions
- Produces and delivers sperm to the female reproductive system.
- Secretes male hormones, primarily testosterone, which regulate sexual development and reproduction.
Role of the Cervix
- Acts as a barrier between the vagina and the uterus, providing protection.
- Facilitates the passage of sperm into the uterus during ovulation.
- Plays a critical role during childbirth, dilating to allow the passage of the baby.
Beginning of Gestation
- Gestation begins with the implantation of a fertilized egg (blastocyst) into the uterine lining.
Duration of Pregnancy
- Human pregnancy typically lasts about 40 weeks, or approximately nine months, counted from the last menstrual period.
Labor in Childbirth
- Characterized by rhythmic contractions of the uterus, leading to cervical dilation and eventually the delivery of the baby.
- Includes stages: early labor, active labor, and the delivery of the placenta.
Two-Fold Cost of Sexual Reproduction
- Involves the energy expenditure in finding a mate and the risk of sexually transmitted infections.
- Includes the half dilution of an organism's genes in offspring, impacting genetic contribution.
Asexual Reproduction
- Process by which organisms create genetically similar or identical copies of themselves without any genetic contribution from another organism.
Forms of Reproduction
- Sexual reproduction, involving the combination of genetic material from two parents.
- Asexual reproduction, involving a single organism or cell creating offspring without fusion of gametes.
Biological Process of Reproduction
- The biological process by which new individual organisms are produced from their parent(s) is called reproduction.
Commonalities of Sexual and Asexual Reproduction
- Both are mechanisms through which organisms produce new individuals, ensuring species survival and continuation.
