Follicular growth and development inside the ovary of a human female is a complex process that involves the maturation of ovarian follicles, which contain the eggs (oocytes). Here's a step-by-step explanation of the process:

1. Primordial Follicles: A female is born with millions of primordial follicles in her ovaries. Each primordial follicle consists of an immature egg surrounded by a single layer of follicular cells.

2. Follicular Activation: Throughout a woman's life, a small number of...

The male reproductive system is responsible for the production and delivery of sperm. It consists of several organs, including the testes, epididymis, vas deferens, seminal vesicles, prostate gland, and penis.

1. Testes: The testes are two oval-shaped glands located in the scrotum (a sac-like structure outside the body). They are the primary male reproductive organs and produce sperm cells through a process called spermatogenesis. Testes also produce testosterone, the primary male sex hormone....

1. Ovaries: These are two small, oval-shaped organs located on either side of the uterus in the lower abdomen. They are responsible for producing and releasing eggs (ova) through a process called ovulation. The ovaries also produce the female sex hormones estrogen and progesterone.

2. Fallopian Tubes: Also known as uterine tubes, these are two slender tubes that extend from the ovaries to the uterus. They serve as a pathway for the eggs to travel from the ovaries to the uterus. Fertilization...

Seminiferous tubules are coiled structures where spermatogenesis occurs. These tubules house Sertoli cells supporting germ cell development and Leydig cells producing testosterone. Sperm cells mature within the seminiferous epithelium and move toward the central lumen. Hormones like FSH and testosterone regulate spermatogenesis. Fully matured sperm are released into the rete testis and progress through the male reproductive system for eventual ejaculation. These tubules generate sperm and...

The accessory reproductive organs of female are :

1. Bartholin's gland

- They are also called great vestibular glands. If these glands become blocked or infected, they can cause pain and swelling. Treatment includes warm compresses, antibiotics, or drainage if necessary.

2. Breasts

- The breasts are the largest accessory reproductive organs in female. Each breast contains of 15-20 lobes of lactiferous tubules which are embedded into fatty tissues. The first milk after parturition is colostrum.

The accessory reproductive organs of male are:

1. Seminal Vesicles

- These are 2 lobulated sacs. It is located between bladder and the rectum. They secrete thick alkaline fluid that mixes with sperm as they pass into ejaculatory ducts.

2. Prostate gland

- It is the largest accessory gland of male reproductive organ. It lies below the neck of urinary bladder. Its secretion mixes with secretion of seminal vesicles and bulbourethral gland to form seminal fluid.

3. Bulbourethral gland

- They are also...

Fertilization happens when a sperm cell combines with an egg cell, resulting in a zygote containing a full set of genetic material. This typically occurs in the fallopian tube post-ovulation. The zygote then goes through rapid cell divisions to become a blastocyst. Implantation, occurring roughly 6-10 days after fertilization, involves the blastocyst adhering to the uterine lining. This process allows for nutrient exchange between the mother and the growing embryo. Hormonal shifts support the...

The term "safe period" pertains to a particular stage within a woman's menstrual cycle, during which the chances of becoming pregnant are considered to be reduced. Generally, it entails refraining from sexual intercourse around the period of ovulation, which is when the egg is released from the ovary and can potentially be fertilized by sperm. This phase usually occurs around the middle of the menstrual cycle. Nevertheless, the effectiveness of the safe period technique is not guaranteed due...
