Human Reproduction and Contraception

Endometrium is a delicate connective tissue sheath that surrounds nerve fibres with a fasciculus. Endometrium is also called Henle's sheath.

Menopause is the transition period in a woman's life when her ovaries stop producing eggs, her body produces less estrogen and progesterone, and menstruation becomes less frequent, eventually stopping altogether. It occurs between the ages of 45 and 55.

LH is produced by the pituitary gland.In women. It helps regulate the menstrual cycle and egg production i.e.ovulation. The level of LH in a woman's body varies with the phase of the menstrual cycle. It increases rapidly just before ovulation occurs, about midway through the cycle (day 14 of a 28-day cycle). This is called an LH surge.

The corpus luteum produces progesterone. Progesterone makes the lining of the uterus thick for implantation and is necessary to sustain a healthy pregnancy. The corpus luteum produces progesterone until the placenta begins to take over progesterone production around ten weeks gestation.

The first menstrual period is referred to as menarche. Each woman has her own individual cycle, usually lasting between 21 and 40 days. The beginning of each cycle is marked by the period. Usually lasting between 3 and 7 days.

Puberty is the time in life when a person becomes sexually mature. It is a physical change that usually happens between ages 10 and 14 for girls and ages 12 and 16 for boys. It is the time at which a growing boy or girl begins the process of sexual maturation.

Vasectomy (in males) and tubectomy (in females) are both surgical procedures designed as permanent methods of sterilization. Therefore, both are correct.

LH (luteinizing hormones) is necessary for final follicular growth and ovulation. So, this answer is right.

Aromatose is an enzyme of the cytochrome group, whose function is to mediate the aromatiztion of androgen, producing estrogens. So, this is correct answer.

During the proliferative phase, uterine glands appear long due to estrogen secretion by the ovaries, not androgen.

  When ovum is not fertilized then corpus luteum degenerates . It is called as corpus albicans or Corpus luteum of ovulation.

During initial follicular growth, the oocyte grows larger, granulosa cells increase in number and a zona pellucida or protein matrix, forms around the oocyte. The fluid filling the follicler continues to accumulate and the cellular surface of the follicle thins in preparation for ovulation. This process can be seen grossly and has been described as a blister on the ovarian surface.

Follicle-stimulating hormone (FSH) causes maturation of a cohort of early-stage ovarian follicles; one of these will ultimately become the dominant or Graafian follicle.

After delivery the myometrium contracts to expel the placenta and to minimise blood loss from  the body.

These glands are located beside the vaginal opening and produce a fluid secretion. It is one of the important parts among the main external structures of the female reproductive system.
